Description:Poria epimiltina (Berk. & Br.) Bres. Fig. 110 Studi Trent. 2(7):75. 1926. Polyporus epvmiltinus Berk. and Br., Linnean Soc. Bot. Jour. 14:54. 1875 (K; BPI). Poria borbonica Pat., Jour. de Bot. (Morot) 4:198. 1890 (FH; BPI; NY; S). P. subargentea Speg., Revista Argen. Hist. Nat. 1:104. 1891 (isotype-BPI). P. sublilacina Ell. & Macbr., n. nudem, in C. L. Smith, Central Amer. Fungi 135. 1896 (lectotype-IA). P. cinereicolor Murr., Mycologia 12:87. 1920 (NY; BPI; FH; K; SYRF).
Occasionally perennial, becoming widely effused, up to 4 mm thick, adnate, without distinctive odor or taste; margin pale bluish gray, farinose, narrow to wide; pore surface pinkish gray or glaucous pale gray, dull, the tubes somewhat corky to rigid and brittle when dry, up to 4 mm long in each indistinct layer, pores subangular, very variable in size, from 4 to 12 per mm, edges somewhat thickened, entire; context pinkish, firm, thin, continuing unchanged into the trama.
Tissue pale golden brown in KOH; hyphal system uncertain, probably dimitic, the context so thin and the hyphae so closely interwoven that the specific characters of the hyphae are uncertain, apparently of skeletal hyphae which are rarely branched, thick-walled to solid, nonseptate, 1.5-3 µm in diameter; cross walls of generative hyphae not found, presumed to be nodose-septate; trama continuous with the context and the hyphae similar; hymenium 7-16 µm thick; cystidia none; basidia subcyclindrical to clavate, 7-14 x 4.5-5 µm; spores hyaline, smooth, IKI -, ellipsoid to ovoid, 4-4.5 x 2-2.5 µm.
On angiosperms in the states bordering on the Gulf of Mexico and evidently distributed throughout the tropical areas of the world; associated with a white rot and the substratum stained intense red. The type of Poria epimiltina is sterile but its identity seems certain. P. dussii Pat. from Guadeloupe is this in part, and consists of P. epimiltina overrun with a sterile white mycelium. Unfortunately P. dussii has been selected as the type for the genus Porogramme Pat. P. vincta is externally similar but differs in having cystidia and simple-septate hyphae.
