Fig. 20 Under this name four collections can be found at Kew: the material labelled (COLENSO b 70) belongs to an undescribed species of Gymnopilus which grows mainly on rotten wood of Leptospermum. The other three collections (COLENSO b 51, b 210, b 311) represent Gymnopilus crociphyllus (Cooke and Massee) Pegler. Spores oval, with distinct smooth plage, otherwise warted, rust-brown, 5-6 X 3.5-4 µ.

Gregarious or caespitose ; pileus convex, then plane, obtuse, often irregular, even, glabrous, surface not becoming broken up, dry, minutely silky under a lens when young, golden-tawny, but becoming pale and yellowish when old, 4-8 cm. across; flesh pallid, thickish at the disc, thinning out towards the margin; gills adnate and subdecurrent when young, often separating from the stem when old, 4-6 mm. broad, crowded, white, then yellow, stained and spotted with brown when old; spores elliptical, obliquely apiculate, 8 x 4-5 µ; stem 5-8 cm. long, up to 1 cm. thick, firm, equal, silky, then fibrillosely-striate, yellowish, base with white down, sometimes rooting, imperfectly hollow; veil flocculose, white, but very fugacious and scarcely evident.
