Saprobic on decaying wood in terrestrial or submerged wood in freshwater habitats. Sexual morph: Ascomata solitary or clustered, immersed or erumpent to superficial, uniloculate, globose to subglobose, somewhat depressed, or ovoid, sometimes collapsed in age, apex blunt, black, coriaceous, ostiolate. Peridium soft, fleshy, often roughened by protruding cells or short hyphae, composed of pseudoparenchymatous cells, light to dark vinaceous brown externally, compressed, hyaline or vinaceous-tinged cells inwardly, pigmented encrust on the surface of outermost cells. Pseudoparaphyses numerous, cellular, flexuous, narrow, hyaline, septate, branched, anastomosing, persistent. Asci 8-spored, bitunicate, fissitunicate, cylindric-clavate, short pedicellate, apically thickened. Ascospores biseriate, elongate-obovoid or narrowly clavate, rounded at the apex, base tapering to a hyaline appendage, uaually slightly curved, brownish to dark brown, transeptate, smooth, thin-walled (Barr 1980; Boonmee et al. 2014). Asexual morph: Coelomycetous. asteromella-like (Barr 1980).
Notes: Rebentischia, typified by R. pomiformis, is characterized by darkly pigmented ascomata, elongate-obovoid ascospores with a base tapering to a hyaline appendage (Boonmee et al. 2014). Barr (1980) placed Rebentischia in Tubeufiaceae based on these characters, which was accepted by Rossman (1987), Lumbsch and Huhndorf (2010) and Boonmee et al. (2011). However, Boonmee et al. (2014) placed it in Pleosporales incertae sedis based on the darkened ascospores with a setiform basal appendage after re-examination of the holotype of R. pomiformis. The asexual morph is not known with certainty, but probably is asteromella-like fungi that grow near the base of ascomata (Barr 1980).
Type species: Rebentischia pomiformis P. Karst.
Other accepted species: Species Fungorum – search Rebentischia.
