Sebacina ocreata (Berk.) Oberw., Garnica & K. Riess, Mycological Progress 13 (3): 468. 2014. Fig. 10 = Thelephora ocreata Berk., Hooker’s Journal of Botany and Kew Garden Miscellany 8: 239 (1856). = Tremellodendron ocreatum (Berk) P. Roberts, Mycotaxon 89 (2): 434 (2004). Notes. Korean collections of Sebacina ocreata largely agree with the original description by Berkeley (1856), exhibiting fully resupinate basidiomata that are firmly attached to herbaceous plants. They form thick, wax-like patches covering the entire plant stem, with a smooth, dull, white (1 A 1) surface and a cartilaginous consistency. However, Korean specimens do not grow upright with acute tips. They also differ in micromorphology, having larger basidiospores (10.7–13.1 × 8.0–9.1 μm) compared to the original description (7–10 × 4–5.5 μm). In comparison with the specimen from Guyana (Henkel et al. 2004), the hymenium of the Korean collections does not turn dark grey when fresh. Distribution. ASIA, EUROPE, SOUTH AMERICA.
