Type species – Didymocrea sadasivanii (T.K.R. Reddy) Kowalski, Mycologia 57(3): 405 (1965).
≡ Didymosphaeria sadasivanii T.K.R. Reddy, Mycologia 53(5): 471 (1962) [1961].
Notes – Didymocrea was introduced by Kowalski (1965) to accommodate D. sadasivanii which was previously known as Didymosphaeria sadasivanii. The sexual morph of Didymocrea is characterized in having brown to black ascomata, filiform pseudoparaphyses, uni-tunicate asci and two-celled brown ascospores (Kowalski 1965, Ariyawansa et al. 2014d). However, due to their unitunicate asci, Kowalski (1965) assigned this in Hypocreales. Subsequently, researchers concluded that it should be a true pleosporalean fungus with functionally unitunicate asci, and retained it in Pleosporales (Luttrell 1975, Aptroot 1995, Rossman et al. 1999, Kruys et al. 2006, Schoch et al. 2009a, Zhang et al. 2012b). According to the multi-gene phylogeny Ariyawansa et al. (2014d) accepted this genus in Didymosphaeriaceae. The asexual morph of Didymocrea was introduced by Jayasiri et al. (2019) and the morphology bears similarity to species in Canalisporium (Sordariomycetes). Only two species have been recorded in this genus, Didymocrea leucaenae, D. sadasivanii (Species Fungorum 2020).
