Saprobic on leaves and stems of various plants in terrestrial habitats. Sexual morph: Ascostromata black, forming at the base of the cypress leaves, superficial on host tissue, solitary to gregarious, erumpent, coriaceous, globose, hyaline. Peridium thick-walled, composed of single layers of brown cells, arranged in a textura angularis. Hamathecium comprising septate, branched, hyphae-like, anastomosting, cellular pseudoparaphyses. Asci 8-spored, bitunicate, fissitunicate, subcylindrical to clavate, with an ocular chamber. Ascospores 2-seriate, ellipsoid to fusoid, dark brown, 3–4-septate, constricted at septa, smooth-walled, with mucilaginous sheath. Asexual morph: Hyphomycetous. Mycelium dark brown, spreading, enclosed in mucus, swollen, ellipsoid, or hyphae forming cellular clumps with endoconidia. Conidia hyaline to brown, thin- to thick-walled, 0–3-septate (Crous et al. 2018a).
Notes – Neocelosporiaceae was introduced by Crous (2018a) to accommodate Neocelosporium, Celosporium and Muellerites. These genera share some characters in both sexual and asexual morphs, and in host-specificity. Neocelosporium has hyaline conidia that primarily arise on the surface of hyphae. Celosporium is characterized by dematiaceous hyphae forming clumps with numerous hyaline to brown endoconidia. Muellerites has been reported only by its sexual morph. Crous (2018a) placed this family in the new order Neocelosporiales based on phylogeny. However, they did not include Zalariaceae in their analyses. In our phylogenetic tree, Neocelosporiaceae formed a clade within Dothideales and basal to the clades of Dothideaceae and Saccotheciaceae. Thus, this family is included as a family in Dothideales.
Type genus: Neocelosporium Crous.
Other accepted species: Species Fungorum – search Neocelosporiaceae.
