Description:Phellinus contiguus (Fr.) Pat. Figure 24 Essai Taxon. (1900) 97; Cunningham (1965) 210 (as Fuscoporia); Thind and Rattan, Indian Phytopath. 24 (1971) 290; Rattan, Biblioth. mycol. 60 (1977) 18; Ryvarden and Johansen (1980) 153; Jahn, Biblioth. mycol. 81 (1981) 68; Gilbertson and Ryvarden (1987) 556; Butler and Wood, Trans. Br. mycol. Soc. 90 (1988) 75-83; Butler, Trans. Br. mycol. Soc. 91 (1988) 677.
Resupinate, widely effused, closely adnate; margin velutinate, thin, determinate or vague, light greyish brown to fulvous. Tubes -0.5 mm long, persistently short, dull ferruginous; pores 200-400 µm wide, dissepiments 40-120 µm thick' and often incomplete or laciniate through growth from a vertical surface, angular, dull brownish drab. Flesh 150-300 µm thick, subfloccose, without a crust, fulvous ochraceous.
On a dead sloping sapling in the forest. Singapore, Jurong, 9 April 1933, Sing. F.N. 28220. Cosmopolitan, warm temperate and tropical.
Spores 5-7 x 2.5-3 µm, white, ellipsoid subcylindric, with thin smooth walls, aguttate or with several guttulae. Basidia 10-13 x 5-6 µm ; sterigmata 4, 3 µm long. Cystidioles present. Setae 40-100 x 7-11 µm conical, straight, acute or rarely obtuse, with thick brown walls and more or less linear aseptate lumen, hymenial or subhymenial; long setae -140 x 12 µm, arising from the flesh and embedded in the dissepiments, obtuse. Hyphae d5, without clamps; skeletals 2-3 µm wide, with smooth walls -1 µm thick, simple, obtuse, copious; generative hyphae 1.5-2.5 µm wide; hyphae in the flesh loosely interwoven, in the dissepiments longitudinal and slightly agglutinated but the dissepiments not carbonaceous.
This description of the Singapore collection agrees with the accounts given by other authors except for the persistently short tubes. They are said to reach 15 mm long and to become indistinctly stratose. Thus the fruit-body is evidently perennial and that from Singapore, though widely effused, may have been only in its first season. The spores may be slightly narrow for others give them as 3-3.5 µm wide. The immersed setae are those formed in the pore-field and not strictly extrahymenial setae. The development of the fruit-body under different conditions of culture is described by Butler and Wood.
