Phanerochaete viticola (Schum.:Fr.) Parmasto, Eesti NSV Tead. Akad. Toim. 16: 389. 1967.

Basionym: Thelephora viticola Schum.:Fr., Schrift. Naturforsch. Gesellsch. (Leipzig) 1: 107. 1822.

 Description: Basidiocarp forming a small patch, ca. 2 × 0.8 mm, ± adnate, reticulate-membranaceous, 200-350 µm thick in section. Hymenial surface Ochraceous-Orange, blackened in KOH, Ochraceous-Buffin at young parts, smooth, not cracked; margin white, thinning, filamentose-fibrillose, encrusted margin cordons extending for several centimetres. Hyphal system monomitic; hyphae simple-septate. Subiculum bi-layered. Basal layer with compact texture, up to ca. 20 μm thick; hyphae horizontal, colorless, ± agglutinated. Medullary layer constituting main part of subiculum, with rather and loosely interwoven, colorless, distinct, fairly straight, 2-4 μm diam., with 0.4-0.7 μm thick walls, covered with scattered crystals, which dissolve in KOH, anastomoses rather frequent. Cystidia variably abundant, projecting for more than half their lengths, not encrusted, cylindrical with narrow bases, with homogeneous contents, 50-100 × 6.5-9 μm, with 0.5-1 μm thick walls. Basidia clavate, with long-stalked bases, slightly constricted in middle, often guttulate, 35-40 × 8-9 μm, 4-sterigmate. Basidioles terminal or pleural. Basidiospores broadly ellipsoid, adaxially flat-tened, smooth, thin-walled, usually with one large oil-drop, 8.5-9.5 × 6 μm, IKI-, CB-.

 Note: The placement of this species in Phanerochaete is questionable for the following reasons: (1) the basidia are guttulate, with stalked bases; (2) the basidiospores are large, each having one prominent oil-drop; (3) a basal layer is present; (4) the hyphae of the me-dullary layer are narrow and mainly vertical.
