 Saprobic, sexual morph: Ascomata 300-600 /um diam., conical, immersed, with an erumpent ostiole. Hamathecium consisting of branched, septate pseudoparaphyses, sparsely anastomosing above the asci, filaments c. 2 um wide. Ascospores fusiform (l-3-septate (17-)24-28(-33) x 6-10 um, with a median constriction, not constricted at the additional septa, middle cells equal, broader but shorter than end cells, ends pointed, surrounded by a 3-5 um thick gelatinous sheath. Senescent ascospores pale brownish and ornamented with small warts. Asexual morph: Undetermined.

Comments:
NOTES: This species appears to be rare and known only from Brunei and this can be attributed to the fact that this host is rarely examined for fungi. It was not isolated by Hyde (1989) and there is no molecular data to support its placement in Lophiostoma. Originally referred to Massarina by Hyde (1989) it was subsequently transferred to Lophiostoma along with many other Massarina species (Hyde et al. 2002).
