Hygrocybe umbilicata, a new waxcap of Hygrophoraceae, is formally described from Bangladesh based on morphological data and molecular evidence of the nuclear ribosomal internal transcribed spacer (ITS) region. This species represents the first record of the genus Hygrocybe for this country. It can be easily recognized by its brilliantly scarlet red...

... ITS dataset includes 41 fungal sequences of tribe Hygrocybeae, and the resulting alignment is 756 nucleotide sites (gaps included), of which 402 are parsimony informative characters. Both ML and BI analyses produced the same topologies, thus only the ML tree is provided in Fig. 1 etymology:-The epithet "umbilicata" (Lat.) refers to the umbilicate ...

... on ITS sequence analyses, H. umbilicata nests in a highly supported clade (90% ML BS, 0.96 PP); it is grouped together with H. cantharellus, H. lepida, H. turunda, H. caespitosa, H. melleofusca, H. sparifolia, and H. papillata (Fig. 1). All of those species are the members of subg. Pseudohygrocybe, sect. Coccineae, subsect. Squamulosae, and are morphologically characterized by their often brightly colored basidiomata ranging from yellow, orange, red, gray or brown with a dry to subviscid pileus that is sometimes hairy or squamulose, and a stipe that is always dry (Arnolds 1990(Arnolds , 1995Bon 1990;Lodge et al. 2014). However, H. umbilicata is nominally clustered with H. sparifolia, H. griseobrunnea, H. caespitosa and H. melleofusca with moderate support (61% ML BS), but they are distinguished from the new species in having ellipsoid to ellipsoid oblong basidiospores, absence of cheilocystidia and generally duller colors (Cantrell and Lodge 2004;Wang et al. 2013;. Furthermore, the Chinese species H. griseobrunnea and H. sparifolia both have trichoderm pileipellis ( Wang et al. 2013;; H. melleofusca, originally described from Puerto Rico, has honey yellow to medium yellow brown with perforated pileus (Lodge & Pegler 1990). Hygrocybe caespitosa, a species originally described from the south eastern USA, has a clay to cinnamon-brown pileus and a yellowish to bright yellow context (Lodge and Pegler 1990;Cantrell and Lodge ...

... The newly generated nrITS and nrLSU sequences, along with the sequences from BLASTn search results and the sequences of Hygrocybe produced from previous studies on Hygrocybe (Hosen et al. 2016;Vizzini et al. 2015;Lodge et al. 2014), were retrieved and were considered for phylogenetic analyses. An LSU sequence-based phylogenetic analysis was conducted for the placement of the new species within Hygrocybe s.s. ...
Hygrocybe indica sp. nov. is described based on specimens collected from Kerala State, India. Morphology-based methods and phylogenetic analyses of sequences of the internal transcribed spacer (nrITS) and nuclear large subunit (nrLSU) of the ribosomal RNA gene were employed to confirm the novelty of this species. The phylogenetic relationship inferred from independent nrLSU and nrITS sequence data matrices confirmed the difference of this new species from other species of Hygrocybe for which DNA sequences are available. The phylogenetic analyses clearly assigned H. indica to the subgenus Hygrocybe. A comprehensive description, photographs of the basidiocarps and the microstructures, and comparisons with morphologically similar and phylogenetically related species and phylograms to depict the placement of the new species are provided.
