Notes

The poorly preserved type (COLENSO 440-217b) made it impossible to find any details necessary for an exact classification.

Omphalia colensoi (Berk.) Sacc. 1887

Description

Pileus thin, rather deeply umbilicate, sometimes almost funnel-shaped, glabrous, entirely covered with very fine radial wrinkles (when dry), margin incurved, 1-1.5 cm. across; gills pallid, rather narrow, slightly decurrent, thin and not distant; spores hyaline, subglobose, about 4 x 3 µ; stem 1-1.5 cm. long, slender, minutely scurfy, then becoming glabrous.

Distribution

Ngaawapurua, Northern Island, New Zealand.

Habitat

On the ground, amongst sand and scraps of wood, wet logs, &c.

Notes

The pileus appears to have been whitish when fresh, stem darker. Distinguished from Omphalia umbellifera by the thin, rather close gills. Type specimens examined.
