Article: Desjardin, D.E.; Horak, E. (1997). Marasmius and Gloiocephala in the South Pacific Region: Papua New Guinea, New Caledonia, and New Zealand taxa. Bibliotheca Mycologica 168: 152 p.
Description: Pi1eus 3-5 mm diam, hemispherical to convex with a central, low, obtuse papilla (often only wart-like), weakly plicate; surface dull, dry, minutely pruinose; off white to pale grey, turning pale reddish brown with KOH; dried pilei appearing like plastic. Texture membranaceous; context very thin, white.-Lamellae adnexed, distant (7-9) with no lamellulae or with a few scattered lamellulae, subventricose, off-white; edges fimbriate, concolorous.- Stipe 12-28 x 0.3-0.5 mm, central, equal, cylindrical, wiry, tough, conspicuously pruinose overall, insititious; apex white, black elsewhere. Odor and taste not distinctive.
Basidiospores 8-11 x 4-5 µm, broadly subfusoid, smooth, thin-walled, hyaline, inamyloid.- Basidia 30-36 x 6-7 µm, subclavate to subcylindrical, 4-spored, clamped.- Cheilogloeocystidia abundant, 45-70 x 6-11 µm, tibiiform, capitulum 7-10 µm diam., thin-walled, hyaline, with reddish brown plasmatic pigment in KOH.- Pleurogloeocystidia absent. - Pileipellis a hymeniform layer of subcylindrical to clavate cells, 20-60 x 4-12 µm, thin-walled, hyaline, with orange resinous contents; capitate pileo-gloeocystidia absent.- Tissues inamyloid, non-gelatinous.- Caulocystidia of 2 types: a) caulogloeocystidia 30-70 x 8-10 µm, tibiiform to fusoid-capitate, thin-walled to thick-walled, capitulum 5-7 µm diam.; walls hyaline, with brown plasmatic pigment; b) scattered caulosetae, 50-60 x 8-10 µm, fusoid to lanceolate, acute, thick-walled (up to 1 µm diam); walls hyaline at stipe apex, brown elsewhere.- Clamp connections present.
Habitat: Habit, habitat and distribution.- Solitary, on rotting twigs of Nothofagus fusca (Fagaceae), not on leaves. New Zealand.
Notes: Gloiocephala nothofagi displays a number of unusual features, including a pileipellis composed of subcylindrical gloeocystidioid cells of varying lengths but lacking projecting capitate gloeocystidia, and caulocystidia of two types, viz. capitate gloeocystidia like those in the hymenium, plus setae. This combination of characters is unique in Gloiocephala. The pigmented pileus would suggest placement in sect. Gloiocephala, subsect. Religiosae.
Macroscopically, G. nothofagi is reminescent of G. caucasica (Sing.) Singer, but the latter species differs in forming thick-walled, broadly clavate to sphaeropedunculate pileipellis cells, and ventricose-mucronate hymenial cystidia (fide Singer, 1937).
