Taxonomy and phylogeny of European Gymnopus subsection Levipedes (Basidiomycota, Omphalotaceae)
نویسندگان
چکیده
The systematic integrity of European Gymnopus subsect. Levipedes is verified based on anatomic-morphological characters with support from DNA sequences of ITS and translation elongation factor 1-alpha genes. Seven species (G. alpinus, G. aquosus, G. dryophilus - including var. lanipes, G. erythropus, G. fagiphilus, G. hybridus, and G. ocior) belonging to this subsection are included. We clarify the concepts of G. dryophilus and G. ocior, which were occasionally confused in older literature. Due to unavailability of previously selected neotype of G. dryophilus the substitute neotype specimen is selected. Gymnopus dryophilus var. lanipes is confirmed as a variety; no important differences from nominotypical variability were detected. All discriminative characters used for identification of these species are discussed in detail. An identification key is also provided.

متن کاملThe sequestrate genus Rhodactina ( Basidiomycota , Boletales ) in northern Thailand
The sequestrate Rhodactina was originally proposed as a monotypic genus to accommodate R. himalayensis and was suggested be a member of the Gautieriaceae because of similarities in spore ornamentation. Our results, based on atp6 sequences, however, place Rhodactina in the Boletaceae. In addition to the type species, a new species, R. incarnata, from northern Thailand is described and illustrate...
متن کاملPhylogeny of the Pluteaceae (Agaricales, Basidiomycota): taxonomy and character evolution.
The phylogeny of the genera traditionally classified in the family Pluteaceae (Agaricales, Basidiomycota) was investigated using molecular data from nuclear ribosomal genes (nSSU, ITS, nLSU) and consequences for taxonomy and character evolution were evaluated. The genus Volvariella is polyphyletic, as most of its representatives fall outside the Pluteoid clade and shows affinities to some hygro...

The genus Astragalus L. (Fabaceae) is reviewed from both phyloenetic and taxonomic points of view. As the largest genus of flowering plants it has attracted many researchers, but much work remains to be done. A short taxonomic history with special focus on infrageneric classification of the genus, a list of phylogenetic studies including the applied markers and sampling strategies as well a...
متن کاملMolecular phylogeny and taxonomy of species of Cousinia section Stenocephalae (Asteraceae) in NE of Iran
In this study, the phylogeny and morphological variation of 6 species of the genus Cousinia sect. Stenocephalae, i.e., C. hypopolia, C. decipiens, C. esfandiarii, C. renominata, C. stahliana and C. daryoushiana, distributed in NE regions of Iran, were investigated. ITS, ETS and rpl32-trnL (UAG) sequences for 12 species (17 specimens) were generated. Phylogenetic interspecies relationships were ...
