Remarks (public):This is my description of the effuso-reflexed form of this species which has, usually, scutelliform fruit-bodies, and it is the one collection that I made in Malesia. The hyphal structure with arboriform skeletals places the species in the small alliance of Tr. perstrata (p. 133). There is no independent binding system.
A collection of scutelliform fruit-bodies, sent to me by Cunningham, namely Auckland, Otau, Hunua Range, leg. J.M. Dingley, May 1949, had exactly the same hyphal construction with slight differences. Thus, the stalks of the arboriform skeletals reached 300 x 2.5-4 µm in flesh and dissepiments and produced from the ends 2-4 binding processes up to700 µm long with their final lengths 100-300 µm tapering into filiform tips 1-1.5 µm wide. The species is said to cause a white rot.

Pileus -25 mm in radius, effuso-reflexed, minutely tomentose, becoming matt or nearly smooth, faintly zoned, pale yellowish fawn, then black from the base outwards; margin subacute. Tubes -2 mm long, fuscous brown; pores 100-140 µm wide, dissepiments 50-70 µm thick, subhexagonal, with a clear grey bloom. Flesh 1 mm thick at the base of the pileus, 0.3-0.5 mm in the resupinate part, rather corky, pliant, dull yellowish fawn, with a thin black crust below the tomentum.
On a small dead branch in the forest. Singapore, Mandai Rd., 13 Oct. 1929. Africa, Asia, Australasia.
Spores 8-11 x 3 µm, white, smooth, subcylindric, obtuse, thin-walled, with a few minute guttulae at each end, inamyloid. Basidia 12-16 x 7-8 µm, rather broad; sterigmata 4, 4 µm long. Cystidia and hyphal pegs none. Hyphae dimitic with arboriform skeletals and intercalary skeletal cells with binding processes, not encrusted, not dextrinoid, the tissue rather oily; skeletals arboriform, terminal, with a stalk 70250 x 2.5-3.5 µm ending distally with 1-5 branches 2-3 µm wide and tapering to subacute tips 1 µm wide, the branches up to 450 µm long (?more) with pale brownish walls -1 µm thick, much interwoven and difficult to separate; skeletal cells intercalary with one to several such binding processes; generative hyphae 1-2.5 µm wide, clamped, thin-walled; dissepiments similar, the skeletal stalks 1.5-2.5 µm wide, their branches 1-2 µm wide and often short. Surface of pileus with the tomentum composed of the loosely projecting binding processes -100 µm long, then subagglutinated at the base into the black crust 30-40 µm thick.
