Mycelium immersed or superficial, branched, septate, dark brown. Conidiomata pycnidial, stromatic, immersed or super- ficial, separate or aggregated, globose, dark brown, uni- or multilocular, often covered by aerial mycelium, formed su- perficially on twigs of pinus or corn straw in culture. Wall dark brown, thick-walled textura angularis, paler and thinner towards the conidiogenous region. Conidiophores absent. Conidiogenous cells holoblastic, determinate, discrete, cylin- drical, hyaline, smooth and thin-walled, formed from cells lining the inner pycnidial walls, 8 − 20 × 2.5 − 4 μm. Paraphyses hyaline, cylindrical, septate, not branched, ends rounded, up to 105 μm long, 3 − 4 μm wide. Conidia acrogenous, up to three-septate, ellipsoidal, hyaline when young, later becoming medianly one-septate, dark brown, thick-walled, frequently with rounded apices, sometimes trun- cate base, 28−35×15−17 μm and longitudinal striations.
