Description: Pileus 2-10 mm diam., pink fading yellowish, hemispherical with a shallow central umbilicus, indistinctly striate, subfibrillose. Gills adnate to slightly decurrent, moderately distant. Stipe 5-10 x 1-2 mm, ochraceous to yellow, central to excentric, straight or curved, smooth to minutely floccose. Spores globose, 6-8 µm diam., amyloid, thin walled. Hymenophoral trama and tissue of pileus pseudo-amyloid, Cheilo- and pleurocystidia ornamented (Fig. 43).
Habitat: On standing dead wood, occasionally on fallen wood, Otari, ig.5.1947, Stevenson; Pinehaven, 21.6.1947, H. Druce; Otari, 11.5.1949, Stevenson (Typus); Woodside, Dunedin, 23.5-1953, Stevenson.

Description: Pileus very thin and delicate, hemispherical, obtuse, at length more or less umbilicate, deeply and distantly striate, glabrous, or flocculosely pruinose or mealy, 4-7 mm. across; colour very variable, blackish, bluish, brown, or grey; gills adnate, with a slight decurrent tooth, broad, somewhat ovate, pallid; spores globose, hyaline, smooth, 9-10 µ, diameter; cystidia obtusely fusiform, 50-60 X 8-10 µ, ; stem about 1 cm. long, very slender, glabrous or minutely scurfy, paler than the pileus, incurved, minutely fistulose.
Habitat: On bark of living trees, among moss and lichens.
Distribution: Dannevirke, New Zealand. Australia, Europe, United States.
Notes: Closely allied to Mycena hiemalis, but readily distinguished by the globose spores, the presence of cystidia in the broad ovate gills, and the densely gregarious habit.

Notes: Probably introduced into New Zealand, growing mainly on lawns around houses and in parks. This species, however, is closely related to an undescribed native fungus.
