Description: Baeospora clastotricha Stevenson (29 D) Fig. 3 = Cystoderma clastotrichum (Stevenson) comb. nov. (Basionym: B. clastotricha Stevenson, Kew Bull. 19: 56, 1964).
This is undoubtedly a member of the genus Cystoderma which is represented in New Zealand by more than four species, according to our present knowledge. Cuticle consists of an epithelium formed by oval or roundish cells, with clamp, connections. Spores oval, hyaline, smooth, amyloid, 3.5-4.5 X 2.5-3 µ. Cystidia none.

Description: Pileus 1-3.5 cm. diam., ochraceous yellow, darker at centre, intensely velvety, plano-convex with down-rolled margin; flesh yellow. Gills adnate, creamy-white, thin, crowded. Stipe 3-7 x 0.2-0.4 cm., ochraceous yellow, paler and silky striate above, more or less clothed with cottony fibrils below, occasionally peronate, hollow, tough. Spores 5 x 3 µm, amyloid, thin-walled; print white. Hymenophoral trama and hyphae of tissues non-amyloid. Basidia with amyloid granulation. Cuticle of globe cells, 15-20 µm diam., with ochraceous yellow pigment, some becoming amyloid, covered by abundant hair-like chains fragmenting into cylindric cells, 3-4 µm broad and 4-8 µm long, some becoming amyloid, containing ochraceous yellow pigment (Fig. 34). Strong unpleasant smell.
Habitat: On fallen wood or rooting' in litter in Nothofagus forest, Keith George Park, 15.6.1949 (Type); & 25-5-1952; Lowry Bay, 6.7.1949, Fringed Hill, Nelson, 3.6.1956; all Stevenson.
Notes: Although the peronate collections appeared different from the smooth-stemmed ones macroscopically, some were intermediate in this respect; all agreed in microscopic characters and thus are treated as one species.

Description: Densely tufted ; pileus deeply umbilicate, often somewhat umbonate but the umbo sunk in the central depression, thin, even, glabrous, white, disc tinged brown, 1-1.5 cm. broad; gills adnato-decurrent, distant, rather broad, white ; spores subglobose, 4-5 µ diameter; stem 1-1.5 cm. long, slender, glabrous, white, hollow.
Habitat: Densely caespitose, on decaying logs.
Distribution: New Zealand. Cuba.
Notes: Distinguished by the much-crowded habit, and the white pileus having the centre depressed and tinged brown.

Notes: Omphalia ? anthiceps Berkeley and Curtis (8, 16) Fig. 2 = Cystoderma clastotrichum (Stevenson) Horak
The microscopical as well as macroscopical characters of the collection (COLENSO b 1023) correspond in all details with this common New Zealand species of Cystoderma, which was originally described as Baeospora clastotricha Stevenson (see there).
