Appressoria alternata vel unilateralis, recta vel curvula, antrorsa, subantrorsa vel retrorsa, 13-27 µm longa; cellulae basilares cylindraceae vel cuneatae, 4-16 µm longae; cellulae apicales ovatae, globosae, truncatae vel leniter lobatae, 8-13 x 6-9 µm. Phialides appressoriis intermixtae, oppositae, alternatae vel unilateralis, ampulliformes, 13-22 x 4-9 µm. Setae myceliales dispersae, simplices, rectae, ad apicem acutae, obtusae vel 2-5 dentatae, ad 400µm longae. Perithecia dispersa, ad 160µm diam.; ascosporae obovoideae, 4-septatae, leniter constrictus ad septatae, 37-44 x 13-16 µm.

Colonies hypophyllous, thin, up to 4mm in diam., confluent. Hyphae crooked, branching alternate to opposite at acute to wide angles, loosely to closely reticulate, cells 13-33 x 4-9 µm.
