CORTINARIUS, Fr.

_Key to the Subgenera._

I. =Phlegmacium=. Partial veil cobwebby. Pileus equally fleshy, viscid; stem firm, dry. p. 177.

II. =Myxacium=. Universal veil glutinous, hence the pileus and scarcely bulbous stem are viscid. Pileus rather thin; gills adnate or decurrent.

p. 183.

III. =Inoloma=. Pileus equally fleshy, dry, at first scaly, fibrillose or innately silky, not hygrophanous. Veil simple. Stem fleshy, subbulbous. p. 185.

188.

V. =Telamonia=. Pileus hygrophanous, at first glabrous or with whitish superficial fibrils. Flesh entirely thin or the margin abruptly so, splitting. Universal veil peronate, or forming a ring low down on the stem, apex somewhat cortinate, hence the veil is double. p. 191.

VI. =Hydrocybe=. Pileus glabrous or covered with superficial white fibrils, not viscid but moist when growing, losing the deep colour and becoming pale when dry, flesh very thin, splitting, disc rarely thicker.

Stem rather rigid, not peronate; veil thin, fibrillose, rarely collapsing and forming an irregular zone round the stem. p. 196.
