Hymenophore pileate, annual, coriaceous, appearing first as scattered orbicular colonies 2-10 mm diameter, when sessile-umbonate with free margins, merging to form linear areas to 8 x 3 cm. Pilei either conchiform-umbonate when solitary and imbricated, or narrowly effused-reflexed, 1-3 cm wide, 1-6 cm long; pileus surface tan, chestnut, or umber, tomentose, abhymenial hairs sometimes arranged in concentric bands of different shades of brown, imbricate and silky, or with depressed or raised parallel concentric ridges and frequently radiately grooved or plicate; hymenial surface at first bay, fulvous, smoky brown, chestnut, or cinnamon, becoming darker when old, tardily creviced either in radiate series, or areolately; margin thinning out, fibrillose, crenate, at first pallid grey, becoming darker, finally concolorous, free. Context tan or ferruginous, 0.3-0.8 mm thick, of parallel hyphae radiately arranged; skeletal hyphae 4-5 µm diameter, walls 1 µm thick, yellow brown; generative hyphae 3-4 µm diameter, walls 0.2 µm thick, hyaline, with clamp connections. Pseudosetae filiform with slightly inflated apices, in sterile plants a few showing false septa, walls brown, thin and encrusted with fine crystals, in fertile specimens walls thickened to 2 µm, seldom septate, encrusted. Hymenial layer when fertile a close palisade of basidia, paraphyses, and scattered pseudosetae, when sterile appearing as a loose palisade of pseudosetae. Basidia subclavate, 24-30 x 7-8 µm, bearing 4 spores; sterigmata erect, slender, to 6 µm long. Paraphyses subclavate, 16-22 x 5-6 µm. Spores elliptical, or elliptic-obovate, 7-9 x 4-4.5 µm, walls smooth, hyaline, 0.1 µm thick.

DISTRIBUTION: South Africa, Australia, New Zealand.

HABITAT: Bark or decorticated wood of dead fallen trunks and stems.

Collections match the type of Stereum schomburgkii in Kew herbarium, ex "Port Denison, Queensland". Talbot (1954, a, p. 316) found this to agree with the type of Thelephora (Stereum) fulva in the herbarium of Paris National Museum, ex "Cap-de-Bonne-Esperance, Drege, 9441". Colour of the surface is at first cinereous, tan, or hazel; later, when pseudosetae replace the basidia, it becomes much darker. D. monomitica resembles D. fulva in macrofeatures, differing mainly in form and colour of the pilei. It differs appreciably in microfeatures; for in D. fulva the hyphal system is dimitic, clamp connections are present in generative hyphae, pseudosetae are of different shape, appreciably thicker in the walls, usually verruculose, and spores are of different shape and slightly larger. As was pointed out by Talbot, the hymenium develops at an early stage, to be replaced by pseudosetae as plants age. In fertile plants the hymenium is composed of a dense palisade of basidia and paraphyses through which scattered pseudosetae project, most forming a dense palisade in the subhymenium. Later the hymenium disappears, when the palisade of pseudosetae takes its place, plants then becoming darker on the hymenial surface.

TYPE LOCALITY: Cape of Good Hope, Africa.
