Mycena corticola sensu Massee 1899 [1898]

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.

Mycena corticola sensu Massee 1899 [1898]

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.

Distribution

Dannevirke, New Zealand. Australia, Europe, United States.

Habitat

On bark of living trees, among moss and lichens.

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.

Mycena roseoflava G. Stev. 1964

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.
