Description:THELEPHORA DIAMESA Ricker - FIG. 32 Thelephora diamesa Ricker in Philipp. J. Sci. I (SuPPI. 4): 284. 1906.
Type: Lamao, Province of Bataan, Luzon, Philippine Islands, coll. Merrill (No. 3510), Oct. 1903 (BPI).
Sporophores 4-7 cm high, 2-4 cm wide, tubular or funnel shaped, tapering into a hollow central stipe, up to 2.5 cm in length. Upper surface glabrous and of a lemon yellow colour when fresh, becoming cream coloured in the herbarium; margin lobed. Hymenial surface smooth, glabrous and orange-yellow when fresh becoming tawny-yellow on drying. Hyphal structure monomitic, consisting of branched hyaline, generative hyphae, 5-10 µm in diam., which have thin but distinct walls, and lack clamp-connexions at the septa. There is no distinct cuticle, although the hyphae which are loosely and irregularly arranged throughout the trama become more densely compacted and horizontally orientated near the surface of the fructification and just above the hymenium. However, these zones are not clearly defined. Hymenium thickening, reaching 156 µm in width, but this thickening does not result in a definite layering. Cystidia and gloeocystidia absent. Basidia 33.8-39 x 7.5 µm, clavate, with pale yellowish-brown granular contents and bearing 4-sterigmata. (Corner in a note with the type material states that the basidia have 4-5 sterigmata.) Spores 7-9.5 x 5-8 µm, hyaline, varying from broadly elliptical to ovate. (Ricker erroneously described them as "globose, hyaline, 2.5-3 µm, in diam." but Corner in a note with the specimen indicated that he found the spores to be 7-8.5 x 6-7.5 µm)
HABITAT: on damp soil in forests during the rainy season.
Thelephora diamesa belongs in the genus Craterellus Pers. sensu stricto and was transferred to that genus by Patouillard as Craterellus diamesus (Ricker) Pat. in Ann. Cryptog. exot. 1: 18. 1928. Corner (1957), however, is of the opinion that this fungus should be regarded as a synonym of C. aureus Berk. & Curt.
It should be noted that Patouillard (1928) described a collection of C. diamesus from Annam and indicated that it occurred in tufts of 6-12 sporophores, and reached a height of 5-10 cm.
