Pileus convex, then expanded, broadly and obtusely umbonate often somewhat irregular, glutinous, radiately rugose or wrinkled, but not distinctly and uniformly striate, brownish-olive, ochraceous-brown, sometimes with a greenish tinge; rarely altogether whitish, 3-10 cm. broad; flesh thin, soft, elastic, white; gills adnexed, narrowed behind, often with a minute decurrent tooth, at length separating more or less from the stem, ventricose, distant, rather thick, white ; spores elliptical, 14-15 X 8-9 µ; stem 8-17 cm. long above ground, up to 1 cm. thick at the base, from where it becomes gradually thinner upwards, glabrous, but at length more or less longitudinally striate or grooved, the greyish-pallid cartilaginous cuticle often twisted, base fusiformly rooting, descending vertically, often as long as the above-ground portion of the stem.

New Zealand. Australia, Tasmania, South Africa, Europe, United States.

In woods, &c., among grass; also in open places.

Readily distinguished by the viscid, radially rugulose pileus, and the long, tapering, polished stem, ending in an equally long, tapering, rooting base. Collybia longipes Bull., a species not yet met with in New Zealand, closely resembles the present species in general habit and appearance, but differs in having the pileus and stem very minutely but distinctly velvety.
