Contributions to the revision of the genus Entoloma (Basidiomycota, Agaricales) in Europe: six new species from subgenus Cyanula and typification of E. incarnatofuscescens.

In anticipation of a phylogenetically revised monograph of Entoloma in Europe, six new species of subgenus Cyanula are described here. Entoloma cistocruentatum is associated with Cistus in Spain, E. dislocatum occurs in montane regions in Catalonia (Spain) and Tuscany (Italy), E. indikon is known from Denmark and three species are mainly distributed in the Nordic countries in Europe: E. calceus, E. perchalybeum and E. praecipuum. Entoloma incarnatofuscescens, from the /Rusticoides clade is neotypified. A fully amended description is given based on molecular evidence, which includes the recently described E. violaceoparkensis and E. klofacianum which became later synonyms.

Phylogeny, taxonomy, and character evolution in Entoloma subgenus Nolanea.

Nolanea is a well-known and long-established subgenus of the genus Entoloma traditionally defined mainly by the mycenoid basidiocarps of the included species. Until now, revisions of this subgenus including molecular data exist only on a regional scale. In this study, the phylogeny of species of Nolanea is analysed based on multi-gene DNA sequences including data of specimens from all continents. New primers are designed for the mitochondrial small subunit and RPB2. The performance of the DNA loci in reconstructing the phylogeny in subg. Nolanea is evaluated. An ancestral state reconstruction is used to infer the character state evolution as well as the importance and reliability of morphological characters used to define subclades below subgeneric rank. Based on the results, seven sections are recognised in Nolanea: the sections Holoconiota, Infularia, Mammosa, Nolanea, Papillata, Staurospora, and the newly described sect. Elegantissima. A large phylogeny based on the fungal barcode rDNA ITS with numerous type sequences is used to evaluate current species concepts. Several names are revealed to be synonyms of older names. Four species new to science are described, namely E. altaicum, E. argillaceum, E. cornicolor, and E. incognitum. Lectotypes, epitypes or neotypes are designated for E. cetratum, E. clandestinum, E. conferendum, E. cuspidiferum, E. hebes, E. minutum, E. nitens, and E. rhodocylix. The re-evaluation of the limits of subg. Nolanea leads to an altered concept excluding species with distinct, lageniform cheilocystidia. The section Ameides is placed in subg. Leptonia. For several species formerly accommodated in Nolanea, but excluded now, viz., E. lepiotoides, E. rhombisporum, E. subelegans, and E. velenovskyi the taxonomic position remains unclear, because of the yet unresolved phylogeny of the whole genus Entoloma.

Phylogenetic and chemical studies in the potential psychotropic species complex of Psilocybe atrobrunnea with taxonomic and nomenclatural notes.

Five Psilocybe species with unresolved systematic position (P. atrobrunnea, P. laetissima, P. medullosa, P. pelliculosa, and P. silvatica) were investigated using four molecular markers (EF1-α, ITS, LSU, and IGS). Phylogenetic analysis revealed that with the exception of P. laetissima, which is now rightfully classified in the genus Leratiomyces, all investigated species belong to Psilocybe sect. Psilocybe. For the first time, psychotropic compounds psilocin and psilocybin were detected in P. medullosa using gas chromatography-mass spectrometry. On the contrary, neither psilocin, nor psilocybin was detected in P. atrobrunnea and negative results were also obtained from mycelia grown in vitro on tryptamine/tryptophan-amended media. These results strongly suggest that biosynthesis of these alkaloids was lost in P. atrobrunnea. With the exception of minor differences detected in EF1-α marker, all sequences of American and European collections of P. atrobrunnea were identical. On the other hand, a thorough nomenclatural study revealed that the name P. atrobrunnea must be considered dubious; the oldest available candidate name, P. fuscofulva, was therefore adopted. The molecular data suggests that morphologically identical American P. silvatica and European P. medullosa likely represent distinct species; epitypes of both taxa were therefore designated.

Entoloma subgenus Leptonia in boreal-temperate Eurasia: towards a phylogenetic species concept.

This study reveals the concordance, or lack thereof, between morphological and phylogenetic species concepts within Entoloma subg. Leptonia in boreal-temperate Eurasia, combining a critical morphological examination with a multigene phylogeny based on nrITS, nrLSU and mtSSU sequences. A total of 16 taxa was investigated. Emended concepts of subg. Leptonia and sect. Leptonia as well as the new sect. Dichroi are presented. Two species (Entoloma percoelestinum and E. sublaevisporum) and one variety (E. tjallingiorum var. laricinum) are described as new to science. On the basis of the morphological and phylogenetical evidence E. alnetorum is reduced to a variety of E. tjallingiorum, and E. venustum is considered a variety of E. callichroum. Accordingly, the new combinations E. tjallingiorum var. alnetorum and E. callichroum var. venustum are proposed. Entoloma lepidissimum var. pauciangulatum is now treated as a synonym of E. chytrophilum. Neotypes for E. dichroum, E. euchroum and E. lampropus are designated.

Multi-gene phylogenetic analyses reveal species limits, phylogeographic patterns, and evolutionary histories of key morphological traits in Entoloma (Agaricales, Basidiomycota).

Species from Entoloma subg. Entoloma are commonly recorded from both the Northern and Southern Hemispheres and, according to literature, most of them have at least Nearctic-Palearctic distributions. However, these records are based on morphological analysis, and studies relating morphology, molecular data and geographical distribution have not been reported. In this study, we used phylogenetic species recognition criteria through gene genealogical concordance (based on nuclear ITS, LSU, rpb2 and mitochondrial SSU) to answer specific questions considering species limits in Entoloma subg. Entoloma and their geographic distribution in Europe, North America and Australasia. The studied morphotaxa belong to sect. Entoloma, namely species like the notorious poisonous E. sinuatum (E. lividum auct.), E. prunuloides (type-species of sect. Entoloma), E. nitidum and the red-listed E. bloxamii. With a few exceptions, our results reveal strong phylogeographical partitions that were previously not known. For example, no collection from Australasia proved to be conspecific with the Northern Hemisphere specimens. Almost all North American collections represent distinct and sister taxa to the European ones. And even within Europe, new lineages were uncovered for the red-listed E. bloxamii, which were previously unknown due to a broad morphological species concept. Our results clearly demonstrate the power of the phylogenetic species concept to reveal evolutionary units, to redefine the morphological limits of the species addressed and to provide insights into the evolutionary history of key morphological characters for Entoloma systematics. New taxa are described, and new combinations are made, including E. fumosobrunneum, E. pseudoprunuloides, E. ochreoprunuloides and E. caesiolamellatum. Epitypes are selected for E. prunuloides and E. bloxamii. In addition, complete descriptions are given of some other taxa used in this study for which modern descriptions are lacking, viz. E. subsinuatum, E. whiteae, E. flavifolium, E. luridum, E. bloxamii, E. madidum, E. corneri, E. callidermum and E. coeruleoviride.

Molecular phylogeny and spore evolution of Entolomataceae.

The phylogeny of the Entolomataceae was reconstructed using three loci (RPB2, LSU and mtSSU) and, in conjunction with spore morphology (using SEM and TEM), was used to address four main systematic issues: 1) the monophyly of the Entolomataceae; 2) inter-generic relationships within the Entolomataceae; 3) genus delimitation of Entolomataceae; and 4) spore evolution in the Entolomataceae. Results confirm that the Entolomataceae (Entoloma, Rhodocybe, Clitopilus, Richoniella and Rhodogaster) is monophyletic and that the combination of pinkish spore prints and spores having bumps and/or ridges formed by an epicorium is a synapomorphy for the family. The Entolomataceae is made up of two sister clades: one with Clitopilus nested within Rhodocybe and another with Richoniella and Rhodogaster nested within Entoloma. Entoloma is best retained as one genus. The smaller genera within Entoloma s.l. are either polyphyletic or make other genera paraphyletic. Spores of the clitopiloid type are derived from rhodocyboid spores. The ancestral spore type of the Entolomataceae was either rhodocyboid or entolomatoid. Taxonomic and nomenclatural changes are made including merging Rhodocybe into Clitopilus and transferring relevant species into Clitopilus and Entoloma.

A phylogenetic study of Boletus section Boletus in Europe.

A phylogenetic study of the species in Boletus sect. Boletus was undertaken using the molecular markers ITS1-5.8S-ITS2 and GAPDH. Four well-supported lineages, one comprising Boletus edulis s.l., the others referring to B. aereus, B. reticulatus and B. pinophilus have been distinguished. The ML and MP trees of ITS showed remarkably low resolution within the B. edulis clade, and confirmed earlier published results, despite the use of samples from a wider geographical area and different hosts. The results of GAPDH demonstrate clearly that this low resolution must be ascribed to a low genetic variability with the B. edulis clade, and make clear that morphological and ecological characters have been overestimated within this species complex. Boletus edulis is therefore defined as a variable species with a wide morphological, ecological and geographic range, and includes several specific and subspecific taxa described in the literature (e.g. B. betulicola, B. persoonii, B. quercicola and B. venturii). Three other European species (B. aereus, B. pinophilus and B. reticulatus) are well delimited species based on morphology and our genetic data.

Evolution and host specificity in the ectomycorrhizal genus Leccinum.

• Species of the ectomycorrhizal genus Leccinum are generally considered to be host specialists. We determined the phylogenetic relationships between species of Leccinum from Europe and North America based on second internal transcribed spacer (ITS2) and glyceraldehyde 3-phosphate dehydrogenase (Gapdh). • We plotted host associations onto the phylogenies using maximum likelihood and parsimony approaches. • Resolution of the phylogeny was greater with Gapdh vs ITS2, plus the Gapdh and ITS phylogenies were highly incongruent. In Leccinum the coding region of Gapdh evolved clocklike, allowing the application of a molecular clock for the reconstruction of host specificity. Almost all species of Leccinum are highly host tree specific, except Leccinum aurantiacum, which associates with a broad range of host trees. Maximum likelihood reconstructions of the ancestral host associations show that this taxon evolved from a specialist. • Our results indicate episodes of rapid speciation coinciding with or immediately following host switches. We propose a model where host niche contraction through geographic isolation and host niche expansion through ecologically equivalent hosts drive cycles of speciation. The role of host race formation and incipient speciation is discussed.
