The Aliquandostipitaceae are a family of aquatic fungi found growing on submerged wood, characterised by wide hyphae and dimorphic ascomata.
Characters (from Pang et al. 2002, as Jahnulales): Ascomata globose, with a stalk or sessile, immersed or superficial, ostiolate, papillate, coriaceous to subcarbonaceous, hyaline, pale brown. Peridium thick, comprising a few layers of relatively large cells. Hamathecium pseudoparaphyses, hyphal-like, filamentous, septate, unbranched between the asci, branching and anastomosing above the asci or septate, branched and persistent, dividing to form loose locules. Asci ovoid, saccate, clavate or cylindrical, thick-walled, bitunicate, persistent or deliquescing, with an apical apparatus. Ascospores ellipsoid-fusiform, apical cell slightly larger, hyaline to brown, slightly constricted at the septum, with or without a mucilaginous sheath.
