Notes: Megalohypha was introduced based on two collections obtained from submerged wood in tropical forest streams in Panama and Thailand. Megalohypha is characterized by hyaline, translucent ascomata, with subtending, wide, brown, septate, stoloniferous hyphae, a peridium of large, thin-walled cells, a hamathecium of septate pseudoparaphyses, clavate, fissitunicate, 8-spored asci and 1-septate, brown, rough-walled ascospores, with longitudinal sulcate striations (Ferrer et al. 2007).
