(Upsaliae): 327 (1838) ≡ Cuphophyllus fornicatus (Fr.) Lodge, Padamsee & Vizzini, comb. nov. Basidiomes tricholomatoid, broadly conical or paraboloid, usually umbonate; surface dry or slightly AZD1390 greasy, smooth, often radially fibrillose-silky near margin, sometimes minutely squamulose at center, gray, grayish brown or pallid with brown tint; lamellae narrowly or broadly attached, often sinuate, not decurrent, broad, white or pale gray, drying opaque; stipe surface dry, fibrillose or fibrillose-silky, often squamulose; stipe context stuffed; pileus margin, lamellar edge and stipe base sometimes bruising rusty red; basidiospores hyaline, smooth, thin-walled, broadly ellipsoid, or obovoid, rarely phaseoliform, mean Q 1.4–1.6, inamyloid, not metachromatic in cresyl blue, uninucleate; BLZ945 mouse basidia 4.8–6 times the length of the basidiospores; lamellar trama subregular or with a subregular mediostratum and interwoven lateral strata, hyphae 20–150 μm long, walls refractive, 0.6–0.8 μm thick in KOH; pileipellis hyphae interwoven near

center and more radially arranged near margin, lacking encrusting pigments, hyphae with a thick gelatinous coating but not an ixocutis; clamp connections abundant, large, medallion form. Lamellae not subdecurrent or decurrent as in other sections of RANTES Cuphophyllus. Phylogenetic support We show strong support for placing sects. Fornicati and Cuphophyllus together in a group that is sister to sect. Virginei (80 % MLBS; 1.0 BPP in the 4-gene backbone analysis, and 86 % MLBS in the Supermatrix analysis, Figs. 1 and 2). In our 4-gene backbone analysis, sect. Fornicati is one of four clades in a polytomy that has strong basal branch support (73 % MLBS, 100 % BPP). In contrast, the ITS analysis by Vizzini and Ercole (2012) [2011] shows Cuphophyllus as polyphyletic, with sects. Cuphophyllus and Fornicati as separate clades in a polytomy, while our ITS-LSU analysis (Fig. 22) shows sect. Fornicati as part of a moderately supported (55 % MLBS) monophyletic Cuphophyllus; none of these analyses, however, have significant backbone support.
