Sphaerostilbella penicillioides  

Anamorph: Gliocladium penicillioides Corda. Mycelium spreading over the hymenium and cap of host, at first white, floccose, becoming golden-yellow, flat and compact; hyphae infrequently branched, yellow, not changing color in 3% KOH. Conidiophores arising throughout the colony from the white, floccose mycelium, becoming scattered in tufts on the golden-yellow, compact mycelium; conidiophores long, erect, hyaline, each with a solitary, hyaline droplet at its tip.
Teleomorph: ascomata perithecia, (185-) 250-320 (-400) x (150-) 200-260 ( -340) µm,  pyriform, seated on the golden yellow mycelium, solitary or gregarious, golden-yellow, not changing colour in 3% KOH, becoming laterally pinched when dry. Peridium smooth, shining, ca 15 µm thick, composed of thin-wall epidermoid cells, becoming progressively more flattened toward the interior. Perithecial papillae obtuse, ( 40-) 60-90 ( -100) µm diam at the ostiolar opening, periphysate. Interascal tissue not present, at least at maturity. Asci (70-) 75-100 (-127) X 3-5 µm,cylindrical, fairly thick-walled but not fissitunicate, the base shortly tapering, the apices rounded with a small ring, 8-spored. Ascospores arranged uniseriately, (7-) 8-11 (-15) x 2-3 µm, fusiform-ellipsoidal to cylindric-ellipsoidal or clavate, slightly constricted at the median to supramedian septum, the apical cell marginally broader and shorter than the basal cell, hyaline, spinulose to warted, without an epispore, gelatinous sheath or appendages.
