However, no convincing arguments have yet provided significant evidence for this congeneric placement. In this study, we analyze material from Exsudoporus species and closely related taxa to assess taxonomic and phylogenetic boundaries between these genera and to clarify species delimitation within Exsudoporus. Outcomes from a multilocus phylogenetic analysis (ITS, nrLSU, tef1-α and rpb2) clearly resolve Exsudoporus as a monophyletic, homogenous and independent genus that is sister to Butyriboletus. An accurate morphological description, comprehensive sampling, type studies, line drawings and a historical overview on the nomenclatural issues of the type species E. permagnificus are provided. Furthermore, this species is documented for the first time from Israel in association with Quercus ca...

We have therefore established comprehensible and reliable species concepts based on statistical evaluation of morphological and ecological characters. We examined many collections from different geographical regions and different developmental stages within collections. Quantitative micromorphological characters (basidiospores, pileipellis end cells) were measured in statistically relevant numbers. The same material was used to generate 24 rDNA-LSU sequences, and the results of phylogenetic analyses clearly confirmed our species concepts : spore size and ornamentation, length of the pileipellis end cells and ' pruinatus-hyphae' are most valuable characters for the delimitation of species in this complex. Molecular data demonstrated that the X. chrysenteron complex is a monophyletic group. All the examined species (X. chrysenteron, X. cisalpinus, X. pruinatus, X. ripariellus, X. dryophilus, X. fennicus, X. porosporus, and X. rubellus) represent independent lineages. The faintly striate spores, a key character characterising species of section Striatulispori, probably evolved independently. In addition, the 'pruinatus-hyphae ' have multiple origins, and truncate spore apices are derived at least twice. Xerocomus cisalpinus sp. nov. is characterised by striate spores, the presence of 'pruinatus-hyphae ' and a pileipellis strongly reminiscent of X. chrysenteron. For reasons of discussion, microscopical data are presented on Boletellus episcopalis for the first time. Xerocomus fennicus (Boletellus) comb. nov. is proposed. We provide descriptions to all included taxa. Our results once more demonstrate that reliably identified and characterised voucher collections are the basic requirement for meaningful phylogenetic studies. * We dedicate this paper to Reinhold Po¨der on the occasion of his 55th birthday.

A fresh look at xerocomoid fungi

Detection of species within the Xerocomus subtomentosus complex in Europe using rDNA–ITS sequences

However, the phenotypic plasticity of these features has resulted in considerable confusion over the delimitation of taxa. In this study, we examined collections attributed to the X. subtomentosus complex in Europe using morphological and rDNA-ITS sequence data. In total, 45 European collections from a wide range of geographical areas and ecological conditions were included in the study. In spite of detecting considerable genetic variation, even within individual basidiomes of X. subtomentosus, molecular data, spore size, flesh colour, and the colour of the basal mycelium allow for the recognition of four distinct taxa: two correspond to X. subtomentosus (13 collections) and X. ferrugineus (20); one X. chrysonemus sp. nov. (10), to date only found in the UK, is described as new; and the existence of another taxon (two; Italy and UK) is noted but left undescribed owing to lack of material. Eight collections from North America were also included in the study, from which two taxa with a close affinity to X. ferrugineus were recognised.

Two of these corresponded to the established taxa X. subtomentosus and X. ferrugineus, and a new taxon, X. chrysonemus, was described. The fourth taxon was noted but left undescribed owing to lack of material. Here, we describe this taxon as X. silwoodensis sp. nov. X. silwoodensis is a rare but widespread taxon known from single sites in Italy and Spain, and three in the UK. The features of X. silwoodensis basidiomes are very similar to other members of the complex but the pileus colours tend to show richer red-brown tones and the stipe often radicates deeply into the substrate. The taxon also exhibits a strong preference for associating with Populus species, whereas the other taxa are associated with either Quercus (X. chrysonemus) or generalists on broadleaved hosts (X. subtomentosus) or conifers and broadleaved trees (X. ferrugineus). Microscopically, the spore characteristics of X. silwoodensis are similar to the recently described X. chrysonemus, but differ significantly from both X. subtomentosus and X. ferrugineus. X. silwoodensis is probably overlooked due to the resemblance to other taxa within the complex. The present study on the identification and description of X. silwoodensis should reduce the confusion associated with the identification of taxa within this species complex and lead to a more accurate assessment of the geographic distribution and conservation needs of the taxa.

A comprehensive nomenclatural study including dates of valid publication, etymology and original ... more A comprehensive nomenclatural study including dates of valid publication, etymology and original spellings of the names Boletus "emilei", Boletus "crokipodius" and Boletus "le-galiae" led us to correct them in accordance with the current Melbourne Code. Consequently, any current name based on these incorrect basionyms also has to be corrected. The original epithet emilei has been corrected by many authors, but never to its correct spelling emileorum according to the data of the protologue. As for the epithet crokipodium, all authors consulted have corrected it to crocipodium without any explanation, and its correct etymology has never been conveniently explained after its original publication by Letellier. We also provide good evidence on the correct date of publication of this name, always misdated in the literature. The epithet le-galiae (with a hyphen), unanimously corrected to legaliae has been very recently resurrected, but according to our nomenclatural study the correct spelling is legaliae. The valid publication and taxonomic status of the current combinations Leccinellum crocipodium, Baorangia emileorum, and Rubroboletus legaliae have also been studied. Finally, all the previous typifications of the three names have been revisited and we conclude that those of Boletus crocipodius and Boletus emileorum have not been effective and, therefore, a new typification is carried out here.
