Development of a typical pseudoparaphysate centrum in Didymosphaeria sadasivanii Ramachandra‐Reddy indicates that this ascomycete is properly placed in the Pleosporaceae despite the fact that forcible discharge of ascospores from bitunicate asci has not been demonstrated. The relatively thin‐walled asci releasing ascospores within the ascocarp in D. sadasivanii , as in Cochliobolus spp., probably were derived by reduction from the bitunicate type. Ascocarps matured on malt agar slants but developed more rapidly and normally on autoclaved alfalfa stems inoculated in medicine bottles and transferred to moist filter paper in large petri dishes when covered by mycelium.
