INTRODUCTION

Cortinarius is the most species-rich mycorrhizal genusin the world occurring in a number of forestecosystems. Recent molecular analyses have shownthat Cortinarius is monophyletic, however they alsoshow that many of the traditional infrageneric groupssuch as Phlegmacium are not monophyletic (Peintneret al. 2004, Garnica et al. 2005). Nevertheless themajority of the species traditionally placed in subge-nus Telamonia do form a monophyletic groupreferred to here as Telamonia s. str. (Peintner et al.2004, Garnica et al. 2005, Harrower et al. 2011).

Telamonia is the most species rich and taxonomi-cally challenging group, and particularly the brown,medium to large species are not well known.Molecular methods have provided new tools for

understanding the diversity and relationships ofCortinarius species, consequently an increasing num-ber of studies on Cortinarius have been published inrecent years (e.g. Frøslev et al. 2007; Ortega et al.2008; Garnica et al. 2009; Suarez-Santiago et al. 2009;Niskanen et al. 2011a, 2012a). The studies byKytovuori et al. (2005a) and Niskanen et al. (2008,2009, 2011b, 2012b) in particular have examined thebrown Telamonia species.

This study focuses on Cortinarius bovinus Fr. andmorphologically similar species occurring in borealconiferous forests in rich forest soils. For severaldecades the name C. bovinus has been applied torather large, fleshy brown Telamonia species byseveral authors (Moser 1978, Soop 2004), but nogenerally accepted survey of C. bovinus and relatedspecies exists.

Section Bovini was described by Moser in 1975(Moser and Horak 1975). The section included thetype species C. bovinus and several South Americanspecies associated with Nothofagus and Eucalyptus. Ina treatment of European species Moser (1983)included C. bovinus, C. fuscoperonatus Kuhner andC. rusticus P. Karst. (syn. C. canabarba M.M. Moser) insection Bovini. Later Moser excluded C. rusticus fromthis section and described a new North Americanspecies, C. pseudobovinus in the Bovini (Moser et al.1995). The treatment of section Bovini by Moser(2001) also included C. sytnikii M.M. Moser fromEurope as well as species from the southern hemi-sphere. Bidaud et al. (2009) included C. ectypus J.Favre and C. subtigrinus Reumaux in the sectionBovini but listed the species under section Brunnei aswell. Furthermore, they present interpretations of theless known C. injucundus (Weinm.) Fr., C. nitrosusCooke, and C. pardinipes Romagn. In addition, thedark brown medium-sized and more or less stoutTelamonia species also have been included in sect.Sordescentes and Brunnei (Brandrud et al. 1989, 1992,1994, 1998; Melot 1990; Bidaud et al. 2002, 2009).These classification systems are presented here(SUPPLEMENTARY TABLE I).

In this study we examined the taxonomy, ecologyand distribution of C. bovinus and morphologicallysimilar, conifer-associated species as well as theirrelationships based on molecular data. We alsostudied available, relevant type specimens. This workis part of our larger ongoing study of the northtemperate and boreal Telamonia species.

MATERIALS AND METHODS

Material.—A total of about 200 collections were studied.Most collections were gathered by us from different parts ofFennoscandia and some from Estonia and central Europe(deposited in H and S). We also examined the herbariummaterial from O and the type specimens mentioned in thebeginning of Molecular analysis. Herbarium acronymsfollow Thiers http://sweetgum.nybg.org/ih/ (continuouslyupdated). For biogeographical provinces in Nordic coun-tries see Knudsen and Vesterholt (2008); for the othercountries provinces are used. Collectors are abbreviated bythe initials Tuula Niskanen (TN), Ilkka Kytovuori (IK), KareLiimatainen (KL) and Pirjo Kytovuori (PK).

Molecular analysis.—Several collections (n 5 3–21) of eachspecies from different geographical areas were sequenced(TABLE I). Also type material of Cortinarius subbrunneusBidaud, Carteret & Reumaux PC0098115 (PC) and C.fratellus Bidaud, Carteret & Reumaux PC0098114 (PC) werestudied. The sequencing of the type material of C. sytnikiiM.M. Moser was not successful. In addition, 19 speciesrepresenting different sections of Telamonia s. str. and/ormorphologically similar species of which no publishedmaterial existed were sequenced (TABLE I).

DNA was extracted from dried material (a piece oflamella) with the NucleoSpin plant kit (Macherey-Nagel,Duren, Germany). Primers ITS 1F and ITS 4 (White et al.1990, Gardes and Bruns 1993) were used to amplify ITSregions and specific primers cort6F and b7.1R (Frøslev et al.2005) for the rpb2 region. The same primer pairs were usedin direct sequencing. PCR amplification and sequencingfollowed Niskanen et al. (2009). Sequences were assembledand edited with Sequencher 4.1 (Gene Codes Corp., AnnArbor, Michigan). A total of 76 new ITS sequences and 46rbp2 sequences were produced (TABLE I) including 15sequences from type specimens. Rpb2 was chosen as asecond molecular marker because Frøslev et al. (2005)indicated that the use of rpb2 increases the resolution andnodal support for phylogenies in Cortinarius.

To determine the phylogenetic placement of the species,we included representatives of different sections of subge-nus Telamonia s. str. in our analysis. Using a BLAST query ofthe public databases (GenBank: http://www.ncbi.nlm.nih.gov/ and UNITE: http://unite.ut.ee/) we also selected allthe sequences similar (, 5 evolutionary events difference)to studied species for the analysis. In addition, morpholog-ically similar species to which we have compared the studiedspecies in this paper or have been classified in sect. Boviniby different authors (SUPPLEMENTARY TABLE I) were includedin the analysis. Two species from subgenus Phlegmaciumwere chosen as outgroup species, as in Niskanen et al.(2011a).

The combined ITS and rpb2 alignment of 142 sequenceswas produced with the program Muscle (Edgar 2004) underdefault settings. The part including ITS sequences wasmanually adjusted in BioEdit (www.mbio.ncsu.edu/BioEdit/bioedit.html). The alignment of rpb2 sequenceswas unambiguous, and no adjustments were made. Theoriginal alignment comprised 1356 nucleotides (includinggaps), and after the exclusion of areas with ambiguous

alignment (positions 443–467) 1331 positions were used foranalysis. Alignment is available at TreeBASE under S13118(http://www.treebase.org/treebase-web/home.html).

Bayesian inference (BI) was performed with MrBayes3.1.1 (Ronquist and Huelsenbeck 2003). The best substitu-tion model for the alignment was estimated by both theAkaike information criterion and the Bayesian informationcriterion with jModelTest 0.1.1 (Posada 2008). GTR modelincluding a gamma shape parameter and estimating theproportion of invariable sites was chosen for both align-ments. Two independent runs with four chains in each wereperformed for 4 000 000 generations with sampling every100th generation. All trees sampled before stationarity werediscarded with a 25% safety margin (burn-in of 10 000 trees[1 000 000 generations]). Sampled trees from both runswere combined in a 50% majority rule consensus phylogramwith posterior probabilities (PP). The analysis was run withcomputer clusters of the CSC, IT Centre for Science, Espoo,Finland.

Morphological studies.—Morphological descriptions arebased on material collected by the authors includingspecimens in all stages of development. Microscopiccharacteristics were observed from dried material mountedin Melzer’s reagent (MLZ). Measurements were made inMLZ with an ocular micrometer with 1003 oil-immersionlens. Basidiospores were measured from the veil or top ofthe stipe, 20 spores from one basidiocarp. The length andwidth were measured for each spore, and their length/width ratios (Q value) were calculated. The lamellar tramaand basidia also were examined, and the pileipellisstructure was studied from both radial freehand sectionsand scalps from the pileus center. The measurements of theelements of pileipellis were made from scalps.

RESULTS

Molecular analysis.—Based on our phylogeneticanalysis (FIG. 1) the studied species were placed insection Bovini (PP 0.91). Four of them, C. bovinus, C.bovinaster, C. bovinatus and C. oulankaensis, formed awell supported clade (PP 1.00) inside sect. Bovini.The section also includes C. aleuriodor, C. sp. (TF-01-034) and a clade comprising C. anisatus, C.neofurvolaesus and C. sordidemaculatus (PP 0.92).

All the species have smaller genetic intraspecificvariation (0–3 evolutionary events) as compared withthe interspecific variation (at least 20 evolutionaryevents) in the ITS regions, except C. fuscobovinus andC. fuscobovinaster. In the ITS region they differ by twobase changes. In the rpb2 region no differences existwithin each species and in general all the sisterspecies pairs differ by fewer than 10 evolutionaryevents. The rpb2 sequences of C. fuscobovinus and C.fuscobovinaster are identical. Intragenomic polymor-phisms were observed in 17–75% of the sampleswithin species. Polymorphisms were not observed intwo species, C. bovinatus and C. bovinaster, but these

Cortinarius sect. Bovini M.M. Moser, Beihefte zurNova Hedwigia 52:430 (1975) em. Liimat., Niska-nen & Kytov.Type species: Cortinarius bovinus Fr.Species medium to large. Basidiomes brown to dark

brown. Stipe often clavate to bulbose, rarely cylindri-cal. Context 6 brown, with age becoming dark brownat least at the base of the stipe. Universal veil white,brownish white or grayish white, in some speciesbecoming grayish brown with age. Mycelium whitish.Odor in most species indistinct or slightly raphanoid.Exsiccatae with dark brown to blackish brown pileusand pale grayish brown to grayish brown stipe. Spores6 amygdaloid to ellipsoid. In coniferous and decid-uous forests. Many of the species either calcicolous orcalciphilous.

Cortinarius disjungendus and some species of sect.Brunnei and Uracei resemble Bovini species, but they

all have blackish exsiccatae (both the stipe andpileus). In addition, the species in sect. Brunnei areoften entirely dark brown, have subglobose toellipsoid spores, and several species have stronglyencrusted lamellar trama hyphae. The species ofsection Uracei have metallic or greenish tints in freshbasidiomes, vinaceous or metallic tints in the blackexsiccatae, and spores that are fairly strongly verru-cose, amygdaloid, or are large (11–12 mm long) andobovoid-ellipsoid. Cortinarius suberi Soop and C.malachius (Fr.) Fr. have dark exsiccatae as well, butthe former has small spores (7.5–9 3 5–5.5 mm) and adistinctly innately fibrillose pileus. The latter has large(9.5–11 3 6–7 mm), weakly amygdaloid and finelyverrucose spores and in fresh condition it is so palethat it would not be confused with species in sect.Bovini.

Illustrations: Brandrud et al. (2012: pl. E20), Soop(2004: pl. 20).

Differential diagnosis: Cortinarius bovinus is charac-terized by a broadly clavate stipe, somewhat waxy-glossyand hygrophanous pileus (two concentric zones withreddish center, like Kuehneromyces mutabilis), universalveil becoming brownish gray, and darkening basi-diomes. The spores are weakly amygdaloid to ellipsoidand fairly strongly dextrinoid. The closely related C.bovinatus, C. oulankaensis and C. bovinaster have amore grayish brown pileus. In addition, C. bovinatushas amygdaloid and coarsely and sharply verrucosespores and C. oulankaensis and C. bovinaster have fairlydistant lamellae and relatively narrower spores. Corti-narius fuscobovinus and C. fuscobovinaster differ fromC. bovinus by having a slightly innately fibrillose pileus,pale brown to brown exsiccatae, and somewhat largerand less verrucose spores. Cortinarius anisochrous haspaler and grayer basidiomess when young, especially inthe context, smaller spores, and exsiccatae withbicolored pileus. Cortinarius impennoides Bidaud,Moenne-Locc. & Reumaux has somewhat paler, moregrayish or yellowish brown pileus, narrower spores,7.5–9 3 5–5.5(6) mm, and somewhat encrustedlamellar trama hyphae. Cortinarius subbalaustinus

Rob. Henry also can resemble C. bovinus, but theformer is usually more slender, has a vivid red-brownpileus, paler context, narrower spores, paler exsiccataeand is associated with Betula.

Cortinarius bovinus was described by Fries (1838) asa fleshy, robust species with a smooth and glossy,hygrophanous, cinnamon-brown pileus drying toyellowish brown. The lamellae were noted as thickand broad and the stipe having a grayish zone butwhite above. The fungus is rare in forests aroundUppsala, Sweden. In his later description Fries (1863)mentions that C. bovinus grows in coniferous forest.No published or unpublished illustrations of thisspecies by Fries exist. Our species fits well with Fries’sdecription: the fleshy shape, and the smooth andglossy, hygrophanous pileus with reddish brown tints.The other, closely related species usually have dullergrayish pileus. Our species also has been found inconiferous forest in the Uppsala area. Furthermore,C. bovinus ss. Soop (2004) and a sequence of C.bovinus (AY669691) published by Garnica et al.(2005) from Germany represent this species. Thephoto collection in Moser and Julich (1990) repre-sents another unknown species in this group, but thatspecies so far is known only from central Europe.Based on this we suggest that the name C. bovinusshould be used for the species presented here and wepropose a specimen-rich and representative collec-tion Kytovuori 04-038 as a neotype of the species. Inearlier literature the name C. bovinus has been usedfor several species, for example the material of C.bovinus in the ecological catalogues of Sweden andFinland (Hallingback and Aronsson 1998, Kytovuoriet al. 2005b) also includes other species of sectionBovini s. str.

Etymology: The name indicates the resemblance to C.bovinus.

Differential diagnosis: Cortinarius bovinaster is rec-ognized by the often small basidiomes, the brown tograyish brown pileus, distant lamellae, and thenarrowly ellipsoid to narrowly obovoid-ellipsoid,finely, densely and evenly verrucose spores. Thespecies seems to have a northern distribution. Theother six species included here are usually larger. Thesister species, C. oulankaensis, is usually stouter andthe spores are larger and coarsely verrucose. Cortinar-ius bovinatus and C. sordidemaculatus differ byamygdaloid spores and denser lamellae. In addition,the spores of C. bovinatus are relatively broader andthick-walled and those of C. sordidemaculatus distinct-ly smaller. Cortinarius bovinus is distinguished bymore reddish brown, waxy-glossy pileus, and thespores are relatively broader.

Ecology and distribution: In mesic coniferous forestswith Picea sometimes with Pinus, on calcareous soil. Itseems to favor well developed natural forests, most ofthe known occurrences are in nature reserves. Rare inboreal zone in northern Europe. The distribution isstrongly concentrated in the northern part of themiddle boreal zone and the southern part of thenorthern boreal zone (SUPPLEMENTARY FIG. 2). Fruit-ing from mid-August to mid-September.

Type: FINLAND. KOILLISMAA: Kuusamo com-mune, Oulanka National Park, between the Campingplace and E part of Puukkorinne, rich grass-herbPicea abies forest with some Pinus sylvestris, Betula andPopulus tremula, on calcareous ground, 27 Aug 2007,Kytovuori 07-877, H6001110 (H, holotype; S and NY,isotype). GenBank JX407321.

Etymology: The name refers to the resemblance to C.bovinus and the uniformly brown exsiccatae, which is oftenbrown unlike the almost blackish exsiccatae of C. bovinus.

NISKANEN ET AL.: CORTINARIUS SECTION BOVINI 989

Differential diagnosis: Typical for Cortinarius fusco-bovinus is innately fibrillose pileus, with persistentlyincurved margin, exsiccatae with uniformly palebrown to brown pileus, and fairly large, broadlyamygdaloid to ovoid spores. The sister species C.fuscobovinaster often has darker exsiccatae, narrowerspores and a more southern distribution. Cortinariusdisjungendus sometimes can be difficult to distuin-guish from C. fuscobovinus in the field, but C.disjungendus has almost blackish exsiccatae and thespores are obovoid. The related C. anisochrous hassmaller spores, the pileus is less innately fibrillose andin exsiccatae bicolored. Cortinarius bovinus, C.bovinatus and C. oulankaensis have darker exsiccataeand the pileus is less fibrillose.

Specimens studied: We included specimens sequenced(TABLE I) and specimens examined (SUPPLEMENTARY TABLE

Etymology: The name refers to affinity to C. fuscobovinus.

Differential diagnosis: Cortinarius fuscobovinaster is amedium-sized, grayish brown species with narrowlyellipsoid to narrowly lacrymoid, fairly large spores, anda southern distribution. The sister species, C. fuscobo-vinus, is most easily distinguished from C. fuscobovi-naster by the spores: The spores of C. fuscobovinus arebroader, 6.1–7.0 mm wide, whereas those of C.fuscobovinaster are 5.4–6.3 mm wide (Fig. 4). Also theshape is different, the spores of C. fuscobovinus arebroadly amygdaloid to ovoid (Fig 2). In addition, C.fuscobovinus has larger basidiomes, paler exsiccatae,and more northern distribution; it is concentrated inthe boreal zone while C. fuscobovinaster is mostfrequent in the hemiboreal zone. The ITS sequencesof the two species do not differ much, only two sites inthe ITS region are different. Nonetheless C. fuscobo-vinaster formed a monophyletic group in our phylo-genetic analysis, however C. fuscobovinus did not,instead it stayed as a basal group to C. fuscobovinaster,so that two distinct groups were not formed. Based onthe correlation of morphological and distributionaldifferences however, we conclude that C. fuscobovinusand C. fuscobovinaster represent two different species.

Cortinarius bovinaster and C. anisochrous can beconfused with C. fuscobovinaster. However, C. bovina-ster has a less fibrillose pileus and darker exsiccataeand C. anisochrous a less fibrillose pileus, palercontext, and somewhat smaller and broader spores.

DISCUSSION

Cortinarius bovinus and similar conifer-associatedspecies.—We studied the C. bovinus group andrecognized six additional conifer-associated speciesfrom northern Europe: C. anisochrous, C. bovinaster,C. bovinatus, C. fuscobovinus, C. fuscobovinaster andC. oulankaensis. The species are characterized bybrown to dark brown basidiomes and exsiccatae withdark brown to blackish brown pileus. The universalveil is white, brownish white or grayish white, in somespecies becoming grayish brown with age, and theodor is indistinct or slightly raphanoid. The sporesseemingly develop fairly slowly, so older basidiomesalways should be included in the exsiccatae. Thespores of young basidiocarps are often somewhatsmaller than those from older ones correlating withthe observation of Niskanen et al. (2011a) from sect.Armillati. The color of the exsiccatae is important foridentifying species. The basiodiomes, however,should be in fresh, good condition when driedbecause those dried in the field yield much lighterexsiccatae. The marginal cells of lamellae are some-what different among the species, but the intraspe-cific variation is fairly high making it difficult to usethem in identification.

Most of the species are rare and occur inhemiboreal boreal and oroboreal coniferous forestsand some species have mostly more northerndistribution. They are all calcicolous and could beused as indicators of valuable forest sites as can thePhlegmacium species (Vesterholt 1991, Hallingbackand Aronsson 1998).

Coverage of the studied species was poor in thepublic sequence databases, as it was for sectionsBrunnei and Armillati studied by Niskanen et al.(2009, 2011a), and only sequences of two species werefound. However, the sequence data can providevaluable information on the ecology and distributionof the species, especially in groups such as sect. Bovinithat include rare and morphologically difficultspecies. This is true particularly in the future whenlarger surveys from different parts on the world areaccomplished.

Species and section taxonomy.—Five of the sevenspecies we recognized fulfill the criteria of a morpho-genetic species (Niskanen et al. 2009). They havedistinctive morphological characters, and pairwiseintraspecific differences (0–3 evolutionary events) inthe ITS regions are smaller than interspecific ones (at

NISKANEN ET AL.: CORTINARIUS SECTION BOVINI 991

least 20 evolutionary events). The two remainingspecies, C. fuscobovinus and C. fuscobovinaster, havemorphological and distributional differences butdiffer only by two evolutionary events in the ITSregion. This is not a unique situation in Cortinariusand the fact that some morphological species haveidentical or almost identical ITS sequences has beenreported in several Cortinarius studies (Garnica 2003,Ammirati et al. 2007, Frøslev et al. 2007, Niskanenet al. 2011a). As stated by Niskanen et al. (2011a), it isimportant to realize that similar ITS sequences arenot necessarily in conflict with the idea of distincttaxa. We lack sufficient data to confirm that ITSregions can separate all Cortinarius species. Usingmore variable regions might resolve the problem.

Based on our phylogeny and morphological data,the studied species were placed in section Bovini. Thesection also includes C. anisatus, C. neofurvolaesus, C.sordidemaculatus, C. aleuriodor and C. sp. (TF-01-034).Our phylogeny also shows that historical groupings ofthe section Bovini are polyphyletic. For example,Cortinarius pseudobovinus belongs to sect. Boulder-enses (Niskanen et al. 2006) and C. ectypus to sect.Brunnei (Niskanen et al. 2009), others did not haveclose relatives in our dataset but were placed outsidesect. Bovini. The sequencing of the type material of C.sytnikii, a species placed in sect. Bovini by Moser(2001) was not successful. Cortinarius sytnikii hasbroadly ellipsoid to subglobose spores (6.5–8.5 3 4.9–5.9 mm). It does not resemble any of the speciescurrently placed in the section Bovini and most likelyhas its closest relatives somewhere else in subgenusTelamonia s. str.
