Pseudohygrocybe (Table 3). Phylogenetic support Subg. Hygrocybe is strongly supported as
a monophyletic clade in two of Poziotinib chemical structure our analyses without inclusion of H. helobia (100 % MLBS in the Supermatrix, 100 % MLBS and BPP in the 4-gene backbone analyses, Fig. 1 and Online selleckchem Resource 6), but only weakly supported by analyses of ITS-LSU (53 % MLBS, Fig. 4), and LSU (54 % & 32 % MLBS, Fig. 3 and Online Resource 7). Previous analyses using fewer species found strong support for a monophyletic subg. Hygrocybe (100 % MLBS in the multigene analysis by Matheny et al. 2006; 95 % MPBS in the LSU analysis p38 MAPK signaling by Moncalvo et al. 2002; 96 % support in the analysis of mostly ITS data by Seitzman et al. 2011). Support for a monophyletic subg. Hygrocybe using ITS sequences alone is not significant for the two spp. in Babos et al. (2011), our 24 spp. (37 % MLBS, Online Resource 8) but high for the 18 spp. in Dentinger et al. (unpublished data, 83 % MLBS). Sections included Type section Hygrocybe; includes existing sections Chlorophanae and Microsporae, and new sections Pseudofirmae and Velosae. Comments Our various phylogenetic analyses, as detailed below, reveal six clades or segments Depsipeptide supplier of grades of which
four are concordant with currently named sections and subsections. These are sect. Hygrocybe with subections Hygrocybe and Macrosporae R. Haller Aar. ex Bon, sect. Chlorophanae (Herink) Arnolds ex Candusso, and sect.
Microsporae Boertm. In addition, we describe two new sections to accommodate monophyletic clades that comprise most of the species with dimorphic spores and basidia, which were previously assigned to sect. Firmae. The position of H. helobia is unstable among analyses, but it also belongs in subg. Hygrocybe. Hygrocybe [subgen. Hygrocybe ] sect. Hygrocybe. [autonym] (1889). Type species: Hygrocybe conica (Schaeff.) P. Kumm., Führ. Pilzk. (Zwickau): 111 (1871) ≡ Hygrophorus conicus (Schaeff.) Fr., Epicr. syst. mycol. (Upsaliae): 331 (1838) [1836–1838], ≡ Agaricus conicus Schaeff., Fung. Bavar. Palat. 4: 2 (1877). Pileus conical or conico-campanulate; lamellae free or narrowly attached; lamellar trama hyphae parallel, some 200 μm in length, with tapered ends and oblique septa. Phylogenetic support Sect. Hygrocybe support varies from high in our 4-gene backbone analysis (97 % MLBS and 100 % BPP; Fig. 1 and Online Resource 6), ITS-LSU analyses (93 % MLBS and 87 % MPBS including H. noninquinans (a replacement name for H. konradii var.
