Description: | Ascomata 300-400 μm wide, 200-260 μm high, subglobose, with a flattened base, immersed, subepidermal, with a slightly erumpent central papillate ostiole, clypeate. Clypeus 180-300 μm long, 45-80 μm wide, black. Peridium 10-20 μm wide, composed of more or less flattened, pale brown pseudoparenchymatous cells forming a textura angularis. Paraphyses up to 1.5 μm wide, hyaline, filiform, unbranched, sparsely septate, deliquescent. Asci 90-120 × 9.5-12.5 μm, cylindrical to broadly cylindrical, unitunicate, thin-walled, 8-spored, short-stalked, with an indistinct nonamyloid apical ring. Ascospores 17-22 × 5.5-8 μm, fusiform, straight, hyaline, smooth, uniseriate to overlapping biseriate inside ascus. | |||

Note: | No species of Physalospora has been reported on Smilax. This species is separable from the closely related P. kalmiae and P. vitis-idaeae by the fusiform ascospores without gelatinous sheath. The ascospores in these two species are obovoid and have a thick gelatinous sheath (Arx & Müller, 1954; Barr, 1970; Scheuer, 1988). | |||
