“…R. pseudogriseus has wider pileus (5.5-9 cm), context white, changing brown when injured, has shorter stipe (6-7 × 1-1.5 cm) and slightly narrower basidia (23-29 × 8-10 µm), and pileipellis thick than R. huanggangensis (Zeng et al 2016). R. sinogriseus has grayish-brown to brown pileus, always cracked into small squamules on grayish to whitish background, has shorter and narrower stipe (6-8 × 1.1-1.5 cm), and pileipellis thinner than R. huanggangensis (Liu et al 2020). R. zhangfeii has wider pileus (5-10 cm), dark purple when young, context gray-white, changing brown to blackish brown when injured (Zeng et al 2016).…”

A new species of the genus Retiboletus, Retiboletus huanggangensis, collected from Huanggang mountain, Wuyishan Nature Reserve, Yanshan County, Shangrao City, Jiangxi Province, China, is described based on morphological and phylogenetic analysis, nuclear ribosomal large subunit (nrLSU), the translation elongation factor1-α gene (TEF1-α) and the RNA polymerase II second largest subunit gene (RPB2) were used for phylogenetic analysis. Retiboletus huanggangensis is morphologically characterized by its white to grayish black to black pileus, white to pale yellow to black stipe, white to pale yellowish white hymenophore, white to grayish white or pale yellow context, prominently and coarsely reticulate over the upper 3/4 or overall, changing orange yellow to rusty yellow when its pileus injured. For phylogenetic analysis, the specimens from Huanggang mountain, grouped together with Retiboletus fuscus, but they have some morphological differences, Retiboletus fuscus has slightly narrower basidia, and pileipellis much narrower. Descriptions and hand drawings of the new species and comparisons with similar species are shown below.

“…Binder & Bresinsky and R. ater Hai Y. Liu, Yan C. Li & Tolgor Bau. However, R. ater can be easily differentiated by its context unchanging when injured(Liu et al 2020). Retiboletus huanggangensis has slightly longer basidospores than R. ater (8-10.5 × 3-4.5 µm), and slightly wider basidia (26-38 × 6-10 µm).…”

Delimiting species in Basidiomycota: a review

Species delimitation is one of the most fundamental processes in biology. Biodiversity undertakings, for instance, require explicit species concepts and criteria for species delimitation in order to be relevant and translatable. However, a perfect species concept does not exist for Fungi. Here, we review the species concepts commonly used in Basidiomycota, the second largest phylum of Fungi that contains some of the best known species of mushrooms, rusts, smuts, and jelly fungi. In general, best practice is to delimitate species, publish new taxa, and conduct taxonomic revisions based on as many independent lines of evidence as possible, that is, by applying a so-called unifying (or integrative) conceptual framework. However, the types of data used vary considerably from group to group. For this reason we discuss the different classes of Basidiomycota, and for each provide: (i) a general introduction with difficulties faced in species recognition, (ii) species concepts and methods for species delimitation, and (iii) community recommendations and conclusions.

Gyroporus species with cyanescent oxidation reactions were investigated, based on morphology and phylogenetic analysis of DNA sequences from the nuclear ribosomal large subunit (nrLSU), the nuclear ribosomal internal transcribed spacer (ITS) and the mitochondrial adenosine triphosphate ATP synthase subunit 6 (atp6). Three species, including two new species, namely G. alpinus and G. flavocyanescens and one previously-described species, namely G. brunneofloccosus, are revealed from China. Collections formerly reported from China as “G. cyanescens” are either G. alpinus or G. flavocyanescens. The new species are documented and illustrated in detail, while the concept of G. brunneofloccosus is refined with additional recently-collected materials. Additionally, the cyanescent species G. pseudomicrosporus, previously described from China, is shown to be a member of the genus Gyrodon, based on re-examination of the type specimen. A key to the cyanescent Gyroporus species from China is provided.
