Soc. linn. Lyon 18: 179 (1949). Etymology: picea – Latin name for the host plant genus, Picea (spruce). Pileus white, viscid when moist; lamellae decurrent, distant, white, sometimes with a weak yellowish
or incarnate tint; stipe white, subviscid when moist, apex dry floccose-fibrillose; no specific odor; ectomycorrhizal with CUDC-907 Picea. Phylogenetic support Sect. Piceae is a moderately supported (78 % MPBS) monophyletic group in the analysis presented by Larsson (2010; unpublished data). find more species included Type species H. piceae. This is currently monotypic, but the analysis presented by Larsson (2010; unpublished data) suggests this is a complex of several taxa. Comments Hygrophorus piceae was placed by
most authors in Sect. Hygrophorus together with other white and pale species, by Hesler and Smith (1963) in subsect. Camarophylli and series Cilengitide concentration Clitocyboides, by Candusso (1997) in subsect. Pallidini [invalid], and by Kovalenko (2012) in subsect. Hygrophorus. It was not treated by Singer (1986) or Arnolds (1990). Hygrophorus , subgen. Colorati (Bataille) E. Larss., stat. nov. MycoBank MB804109.

Limacium [unranked] Colorati Bataille, Mém. Soc. Émul. Doubs, sér. 8 4: 158 (1910) [1909]. Hygrophorus, subgen. Colorati emended here by Larsson to exclude sect. Discoidei. Basidiomes glutinous from a universal veil or dry to subviscid, with or without a partial veil sometimes forming an annulus; pileus usually colored, at least in the center or white to lightly pigmented. Phylogenetic support Our LSU analysis shows subg. Colorati as a paraphyletic grade with 72 % MLBS support for the branch separating it from sect. Chrysodontes (subg. Camarophylli). Our Supermatrix analysis also shows subg. Colorati as a grade, but with sect. Chrysodontes within it; there is no significant support for these branches. Our ITS-LSU analysis also shows a polyphyletic subg. Colorati. Our ITS analysis (Online Resource 9) shows subg. Colorati as a paraphyletic grade, but sect. Aurei is polyphyletic. In the analysis presented by Larsson (2010, unpublished), subg. Colorati is a monophyletic group lacking significant support, but the inner clade comprising subsects. Olivaceoumbrini, Pudorini and Tephroleuci has 71 % MPBS. Sections included Sects Aurei (Bataille) E. Larss., stat. nov., Olivaceoumbrini, and Pudorini. Comments Bataille (1910) created five unranked groups within Colorati, of which one name was from Fries (1874) (i.e.
