g., in Arnolds 1990), it was previously published by P. Hennings in Engler and Prantl (1889) (see Young and Mills 2002). Hygrophorus Fr., Fl. Scan.: 339 (1836) [1835]. Type species: Hygrophorus eburneus (Bull. : Fr.) Fr., Epicr. syst. mycol. (Upsaliae): 321 (1836) [1836–1838] ≡ Agaricus eburneus Bull., Herb. Fr. 3: tab. 118 (1780) : Fr. Characters are the same as in tribe Hygrophoreae. Phylogenetic support Support is same as for tribe Hygrophoreae. Subgenera included We recognize three subgenera: Hygrophorus emend., Colorati find more (Bataille) E. Larss., subg. nov. and Camarophyllus

Fr., emend. Comments Selleckchem Quisinostat species of Hygrophorus ss have a characteristic divergent lamellar trama (Fig. 19) which sets them apart from all other Hygrophoraceae (Young 1997; Hesler and Smith 1963, as Hygrophorus subg. Hygrophorus). The genus Hygrophorus was formally described by Fries in 1836. Later, in Epicrisis Sytematis Mycologici, Fries (1838) organized species into unranked, infrageneric ‘tribes’. Most of the species now classified as Hygrophorus s.s. (including the type species, H. eburneus) were from part of Fries’ Hygrophorus tribe Limacium and the remainder are from

part of AG-881 Fries’ Clitocybe tribe Camarophyllus. Fries designated these tribes as Hygrophorus subgenera in 1849, they were treated as subgenera by Karsten (1876), but treated as genera by Kummer (1871) and Karsten (1879). An overview of the major classifications from Fries (1821) to Bon (1990) is given by Candusso (1997).

As the micro-morphological characters are similar in most Hygrophorus species the current classifications are still based on basidiocarp color, color changes, and the presence or absence of a universal glutinous veil and specific odors (Hesler and Smith 1963, Singer 1986, Arnolds 1990, Candusso 1997; Kovalenko 2012). Fig. 19 Subf. Hygrophoroideae, tribe Hygrophoreae, Hygrophorus hypothejus var. aureus lamellar cross section (DR-2146, DJL02DR43, Dominican Republic). Scale bar = 20 μm In Epicrisis Fries (1838) recognized twenty species in the tribe Limacium. Fries (1874) introduced five groupings below tribes based on pileus color; Albi l. albolutescentes for the white to yellow species; Rubentes for IKBKE the red to reddish species, Fulventes l. flavi for the brown to tan or bright yellow species; Olivaceoumbrini for the olivaceous species; Fuscocinerei l. lividi for the gray to blackish species. Bataille (1910) similarly did not designate ranks below subgenus in Hygrophorus, and he used part of Fries’ classification. Many of Fries’ and Battaille’s names have subsequently been combined by other authors at designated ranks. Important modifications by Bataille (1910) were use of type species and addition of morphological characters besides pileus color. Bataille also inserted unranked names between subgen. Hygrophorus and species groups, Albi (from Fries), later renamed sect. Hygrophorus by Singer as it contains the type species (Art. 22.1), and Colorati.
