Scopaphoma corioli

Scopaphoma corioli Dearn. & House, N.Y. St. Mus. Bull. 266: 83 (1925)

Facesoffungi number: FoF 07734

 

Fungicolous on Polyporus sp. (Polyporaceae). Sexual morph: undetermined. Asexual morph: Conidiomata 220–280 µm diam., 200–300 µm high, brown to dark brown, pycnidial, solitary to gregarious or confluent, immersed to semi-immersed, papillate ostioles visible in surface view, globose to subglobose, unilocular, glabrous, thick-walled. Ostiole circular, papillate, centrally located. Conidiomatal wall 20–50 µm wide, composed of thick-walled, brown to hyaline cells of textura angularis. Conidiophores formed form the innermost cells of conidiomata, hyaline, branched, septate, smooth-walled. Conidiogenous cells 10–20 × 1–3 µm, hyaline, subcylindrical to lageniform, integrated, indeterminate, smooth-walled, Conidia composed of a 2-celled, hyaline, ellipsoidal to subcylindrical, straight or slightly curved conidium body 4–14 × 1–2 µm ( = 8 × 1.3 µm; n = 30), apical cell attenuating to flexuous, filiform, tubular, unbranched appendage 5–19 μm long ( = 11 μm) towards apex, basal cell bearing an unbranched, tubular appendage 1–3 μm long ( = 2 μm), separated from the conidium body by a septum.

 

Material examined: Canada, Ontario, Waterloo, Columbia & Erbsville Rd, on Polyporus sp. (Polyporaceae), May 1981, F. DiCosmo (DAOM 215577).
