Description

Sexual morph: Ascomata on host surface 280–500 μm in diam., in vertical section 410–480 μm high, 680–980 μm in diam., solitary, immersed to erumpent, black, carbonaceous, conical or subglobose, with a central ostiole or papilla, clypeate. Peridium up to 55 μm wide, composed of brown cells of textura epidermoidea and inner layers with cells of textura angularis. Clypeus composed of host cells interspersed with darkened fungal tissue. Hamathecium comprising 1–1.5 μm wide, numerous, anastomosing, branched, septate, trabeculate pseudoparaphyses, embedded in a gelatinous matrix. Asci 140–275 × 23–30 μm, 8-spored, bitunicate, fissitunicate, cylindric-clavate, pedicellate, with an apical apparatus consisting of a large distinctive ocular chamber and prominent ring. Ascospores 46–62 × 16–24 μm ( = 51.9 × 17.9 μm, n = 20), uniseriate or biseriate, hyaline to brown, broad fusiform or ellipsoidal, 2-celled and almost equally, strongly constricted at the central septum, with hyaline apical germ pores, smooth-walled, lacking a mucilaginous sheath. Asexual morph: Undetermined.

 

 

Culture conditions: Colonies growing well on PDA and MEA, and attaining 13 mm diam. on PDA within 21 days at 25ºC under natural light, velvety, circular, milky white and central darker or pale brown, reverse brown, with a margin of translucent, milky white to hyaline mycelia.
