Porosphaerella cordanophora E. Müller & Samuels, Sydowia 35: 150. 1982.

 Description: Subiculum inconspicuous, superficial, composed of sparsely interwoven hyphae that penetrate deeply into host tissues. Ascomata superficial to partly immersed in subiculum, scattered, solitary to gregarious, broadly ovate to subglobose, 155-240 μm diam., with a papillate, periphysate ostiole. Peridial hyphae protruding from the sides and base of ascoma and intermixed with hyphae of the subiculum. Peridium 15-25 μm wide, composed of dark brown, thick-walled, polygonal to oblong cells. Asci 65-85 × 5-7 μm, cylindrical, basal, unitunicate, shortly stipitate, with an inconspicuous, non-amyloid apical ring, and maturing at different times. Paraphyses 1.5-2.5 μm wide, branched at upper part, gutullate. Ascosportes 10-14 × 4-5 μm, elliptical to elliptic-fusiform, 1-septate at middle, brown, with germ pores at both ends. Conidiophores and conidia of the anamorph found near the ascomata, but conidia not found attached with conidiophores. Conidia 9-12 × 5-6 μm, broadly elliptical to ovoid, dark brown, with a dark and thick septa in the middle, hilum at both ends, Conidiophores subulate, 4-6 μm wide, up to 180 μm long, erect, unbranched, pale to dark brown, with a basal swelling that produces rooting hyphae to anchor to the host and penetrate into the host tissues.
