Basionym:— Hygrocybe ovinoides Lodge, S.A. Cantrell & T.J. Baroni, Mycological View in CoL Research, 108(11): 1312 (2004)

Type:— PUERTO RICO. Río Grande: Caribbean National Forest, Caimitillo trail, upper part, 730 m, 18º18’17”N, 65º47’20”W, 11 June 1997, on clay soil, T. J. Baroni ( CFMR-PR 4547 , holotype) GoogleMaps .

Comments:—This taxon was first accommodated in Hygrocybe subgen. Pseudohygrocybe Bon sect. Neohygrocybe Herink ( Cantrell & Lodge 2004) . However, most species arranged under sect. Neohygrocybe by Cantrell & Lodge (2004) were recombined to genus Neohygrocybe after molecular analyses ( Lodge et al. 2013). Resembling the European taxon Neohygrocybe ovina (Bull.) Herink (1958 [1959]: 72), this species lacks an odour, or red to brown staining reactions and has a characteristic whitish band in the pileus margin ( Cantrell & Lodge 2004). The dark dull colours of the basidiomata, which is entirely greyish, the radially fibrillose pileus which is somewhat dry to moist, but not viscid, sinuate lamellae, fibrillose-silky stipe and the microscopic features, such as the ellipsoid basidiospores, basidia with modest clamp connections at the base (not the toruloid or medallion type), regular lamellar trama, presence of pseudocystidia emerging from the trama, presence of fuscous pigments in the pileipellis hyphae and presence of clamp connections throughout the basidiomata are sufficient to accommodate it under Neohygrocybe ( Cantrell & Lodge 2004, Lodge et al. 2013). This taxon, due to the lack of staining reactions, would be better placed in sect. Tristes (Bataille) Lodge & Padamsee ( Lodge et al. 2013).
