Description:Cymatoderma elegans Jungh. Pl. X. figs. 2-4; Pl. XI. figs. 1-4; Pl. XII. fig. 1.
Cladoderris scrupulosa Lloyd "Synopsis of the genus Cladoderris" p. 8 in Mycological Writings 4, 1913.
Sporophores up to 13 cm from stalk to margin, and 14 cm in width, coriaceous, dimidiate, fiabellate and pseudoinfundibuliform, with short lateral or long pseudocentral stipe; adjacent fruitbodies frequently becoming confluent. Pileus often completely covered by a thick felt-like tomentum which obscures the underlying radiating knife-edged ridges on the surface of the sporophore, although their presence is frequently indicated by striking rugosity. The tomentum in herbarium material varies in colour from fawn, often with brown or ochraceous tones to tawnybrown or snuff-brown in ancient collections. Hymenial surface varying from beige, ochraceous-beige or pinkish-brown to ochraceous-brown (rarely dark purplish-brown in very old material), and ornamented with rather prominent, branched, radiating folds which bear scanty or densely crowded warts or spines. The hymenial folds tend to be united behind into "main branches" which radiate from the stem. Stipe up to 5 cm long, 0-8 cm wide, covered by a thick fawn or brown felt-like tomentum. In dimidiate or flabellate sporophores the stipe is short or rudimentary, but it tends to be well developed in fruitbodies which are pseudoinfundibuliform. Flesh pallid wood colour. Hyphal structure dimitic; generative byphae of two kinds (1) thin-walled, twisted and ribbon-like, 2-4 :m in diam., (2) thickwalled and up to 6 :m in diam.; skeletal hyphae, 3-5(-8) :m in diam., tapering to narrow obtuse, often thin-walled apices [for further details of hyphal morphology see generic description]. There is a distinct cuticular layer, 26-30 :m in thickness, formed of much branched coralloid hyphae 2-5-3 :m in diam., which appear to be modified generative hyphae. It is from this zone that the hairs forming the surface tomentum of the pileus arise. These are thick-walled, except towards the apices which may be thin-walled, and 3-5 :m in diam., [for additional information see generic description]. Hymenium thickening, reaching 310 :m. Cystidia present as apically encrusted metuloids, 17.5-47 x 7.5-10 :m, varying in shape from clavate or lanceolate to obpyriform. Gloeocystidia often abundant, although tending to collapse in old collections, as long, thin-walled, undulating bodies with somewhat swollen bases. Basidia clavate, usually 4-spored but sometimes 2-spored, 39-50 x 5-6 :m. Spores (6-)6.5-9 x (3.5-)4-5 :m, hyaline, broadly elliptical to elliptical.
Habitat: on dead stumps, trunks, fallen branches, etc. It has been collected on Erythrophloeum fordii (Heim & Malençon 1928), Mocranga denticulata, Phoenix reclinata and Cacao.
Distribution: tropical Africa and Asia, but not known in South America.
