Teleomorph in nature: Subiculum orange to deeporange, covering a part or entire surface of host hymenium; Perithecia yellowish brown, in KOH lilac to red, ellipsoid to longellipsoidal, 324-350 x 211-343 m. Asci cylindrical, 8-spored.  Ascospores hyaline, fusiform, always equally two-celled, (17.5-)19-20(-25.5) ~ (3-)4-5 m, verrucose with prominent warts, apiculate at both ends. 

Characteristics in cultures: Colonies on MA grow rapidly to reach 90 mm in diam. after 7 days at 25oC, floccose, white to pale yellow, reverse absent. Conidiogenous cells born at the apex or laterally as a well-developed verticil of 3-5 on the conidiophores. Conidia produced long chains from the apex of conidiogenous cells, hyaline 0-1septae, broadly ellipsoidal, thin-walled, smooth (8.0-)11.0-13.0(-14.5) X (5.0-)7.0-9.0 m.Chlamydospores produced in chains laterally on the substrate hyphae or apically at the apex of the branches, subglobose to ellipsoidal.
