Subgenus Inocephalus

Habit mycenoid, inocybeoid, more rarely tricholomatoid. Pileus fibrillous, squamulose, velvety or granulose; pileipellis usually trichoderm-like, sometimes a rather regular hymeniderm or calliderm. Usually with intracellular, more rarely with additional incrusting pigment; clamp-connections usually present.

Fruitbodies with grey or brown colour; with tibiiform to ampullaceous cheilocystidia.

Species: E. carbonicola Noordel.; E. lilacinoroseum Bon & Guinberteau

WIth cuboid or stellate spores. Pileus smooth or fibrillose to squamulose, usually with intracellular pigment, more rarely incrusting

Species: E. conferendum(Britz) Noordel. mit var. pusillum (Velen.) Noordel. und var. ,i>incrustatum (Largent & Thiers) Noordel. & Hauskn.; E. rhombisporum (Kühn. & Bours.) Horak; E. prismatospermum (Romagn.) Horak; E. percuboideum Noordel. & Hausknecht; E. galericolor Courtecuisse

Section Phlebophora Noordel.

Pileus strongly wrinkled or veined, reminiscent of a Pluteus species. Cheilocystidia usually present; pileipellis a transitions between a cutis and a trichoderm of broad hyphae with intracelular pigment; in addition also incrusting pigment present in deeper layers of pileipellis.

Species: E. kitsii Noordel.

Section Erophila (Romagn.) Noordel.

Habit inocybeoid or almost tricholomatoid with a finely fibrillose to squamulose, not hygrophanous pileus. Without or with scattered, inconspicuous, cylindrical to clavate cheilocystidia; with intracellular pigment. Often occurring in spring.

Species: E. plebejum (Kalchbr.) Noordel.; E. opacum (Velen) Noordel.; E. plebeioides (Schulz.) Noordel.; E. resutum (Fr.) Quél.; E. vezzaneense Noordel. & Hauskn.

Section Calliderma (Romagn.) Noordel.

Habit triholomatoid or inocybeoid; pileus velvety to granulose; pileipellis a trichoderm or calliderm of short, clavate to rounded elements with intracellular pigment; often without clamp-connections.

Section Pallideradicata Noordel. & Hauskn.

Pileus finely fibrillose to squamulose; pileipellis a trichoderm of broad elements with intracellular pigment; stipe often rooting.

Section Hispiduli Noordel.

Habit inocybeoid with strongly fibrillose to squamulose pileus; pigment intracellular and often also incrusting. Formerly these species were classified in sect. Leptonia. But, with the discovery of E. sanvitalense I feel that they are better placed in the current subgenus on account of the habit and the type of pigmentation.

Species: E. hispidulum (M. Lange) Noordel.; E. sanvitalense Noordel. & Hauskn.
