Pseudohygrocybe except basidia and spores always monomorphic. Phylogenetic support There are too few species in our 4-gene backbone analyses to draw conclusions regarding subg. Pseudohygrocybe sections. The ITS-LSU analysis shows strong (91 % MLBS) support for a branch connecting subsects. Coccineae and Siccae, while subsect. Squamulosae appears as a separate clade. The grade in our Supermatrix analysis has a branch with low support (44 % MLBS) subtending learn more subsects. Coccineae and Siccae, while subsect. Squamulosae is basal (60 % MLBS). Our Hygrocybe LSU analysis (Online Resource 7) shows sect. Coccineae as a grade with strong support for subsect. Squamulosae (97 % MLBS). Subsections included There are currently three validly named subsections in sect. Coccineae, namely Coccineae, Siccae and Squamulosae. Comments Both Hygrocybe sects Coccineae and Puniceae were first validly published by Fayod (1889) in the same publication. Singer [(1949) 1951, p. 152] recognized that the type species of these
two sections, H. coccinea and H. punicea, belonged in the same section, and between the two competing names he selected Coccineae over Puniceae. Thus sect. Coccineae is the correct name for this group. Previously, Singer (1943) had erected sect. “Inopodes”, nom. invalid, which contained S3I-201 purchase aminophylline H. punicea (lacking a Latin description, Art. 36.1). Hygrocybe [subg.

Pileus brightly colored, lubricous or viscid at least when young. Lamellae broadly adnate or slightly sinuate, sometimes with a decurrent tooth. Basidiospores usually narrow (mean Q 1.5–2.4), often constricted; mean ratio of basidia to basidiospore length > 5. Pileipellis a persistent or ephemeral ixocutis or mixed ixocutis-ixotrichodermium with narrow hyphae (2–5 μm wide) embedded in gel over hyphae of moderate diameter (6–12 μm wide). Chains of ellipsoid to subglobose hyphal elements generally absent from the hypodermium. Phylogenetic support Our ITS-LSU analysis strongly supports subsect. Coccineae as a monophyletic clade comprising H. coccinea and H. punicea (100 % MLBS, Fig. 4). Our Supermatrix strongly supports subsect. Coccineae (H. coccinea, H. punicea and H. purpureofolia) if H.
