Mycelium immersed or superficial, branched, septate, dark brown. Conidiomata pycnidial, stromatic, superficial, sepa- rate, globose, dark brown, unilocular, often covered by aerial mycelium, formed superficially on twigs of pinus or corn straw in culture.

Conidiogenous cells holoblastic, deter- minate, discrete, cylindrical, hyaline, smooth and thin-walled, formed from cells lining the inner pycnidial walls, 7 − 15 × 2 − 5 μm. Paraphyses hyaline, cylindrical, septate, occasionally branched, ends rounded, up to 70 μm long, 3 μm wide. Conidia acrogenous, aseptate, ellipsoid to ovoid, hyaline when young, later becoming medianly one-septate, dark brown, thick-walled, rounded apices, frequently truncate base, 22−26×14−17 μm and longitudinal striations.
