Lichenomphalia velutina (Quél.) Redhead, Lutzoni, Moncalvo et Vilgalys.

Lichenized Basidiomycota (Basidiolichen).

     Thallus formed by globules of hyphae retaining an algae (Coccomyxa), granular in dry weather, a little gelatinous in wet weather, bright green. Omphaloid basidioma with a cap slightly depressed at the beginning then slightly funnel-shaped, 0.5-1.5 cm in diameter, more or less striated, grayish-brown to pale grayish, sometimes a little brownish, cuticle formed of hyphae encrusted by a "zebroide" gray-brown pigment. Decurrent, concolorous but paler gills. Stipe 1-2.5 cm high, concolor at the cap, finely pubescent (at least in its lower part). Basidia predominantly bisporic 17-28 x 4-7 µm. Spores broadly elliptical to pyriform, 7-10 x 4-6 µm. Clamp-connection absent in all hyphae. Rather rare species occurring on acidic and mossy soils.

N.B. Very variable and perhaps collective species, having given an impressive inextricable synonymy ...
