Notes on all genera of Omphalotaceae: Expanding the taxonomic spectrum in China and revisiting historical type specimens

Popis výsledku v původním jazyce

Since the 1990s, Gymnopus sensu lato has undergone significant taxonomic revisions, which have led to elucidative taxonomic and systematic studies in Omphalotaceae. These revisions are characterized by the introduction of five novel genera and the reallocation of specific taxa to existing genera, all aimed at rectifying their polyphyletic status. However, the persistent polyphyletic nature of Gymnopus is underscored by the distinct lineage within the basal clade formed by the reference sequences of G. contrarius, which stands apart from the primary Gymnopus clade. The classification of this ambiguous clade remains a mystery. The species&apos; original description was re-evaluated and refined based on the examination of the two related type specimens and further bolstered by continuous research on new samples from China. A century-old type specimen from the USA has enabled its sequence to be included in a comprehensive molecular phylogenetic analysis of Omphalotaceae. This investigation employed two markers, the internal transcribed spacer (ITS) and the nuclear large subunit (LSU), were used to explore phylogenetic relationships between genera. Through detailed morphological assessments against recognized genera, this clade was validated as a unique monotypic genus, leading to the proposal of Peckorumyces gen. nov. This new classification bridges existing morpho-phylogenetic gaps and addresses the longstanding polyphyletic issue of Gymnopus. To compare with this unusual &quot;Gymnopus&quot; species, 20 taxa within Omphalotaceae were studied, including 15 new species and five known species. Among these taxa, one genus and three species are new to China. In addition, nine new combinations were made based on phylogenetic analyses. This study is enriched with vivid colour photographs, line drawings of microscopic structures, detailed description of the new genus, and well-sampled phylogeny.
