Classification: Xylariales, Xylariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi

Saprobic on bark of woody plants. Sexual morph: Stromata superficial, erumpent, pulvinate or discoid, reddish-brown, subglobose, soft-textured, with pseudoparenchymatous cells, with black ostiole. Ascomata perithecial, dark brown to black, immersed, globose, ostiole periphysate. Peridium comprising rows of cells, externally brown, internally hyaline. Paraphyses hypha-like, septate. Asci 8-spored, unitunicate, clavate, or fusoid, short pedicellate, with a shallow, J-, apical ring. Ascospores 1-3-seriate, hyaline or brown, filiform, aseptate or 1–3 septate, cylindrical or falcate. Asexual morph: Coelomycetous. Mycelium hyphae to yellow-brown, septate, branched. Conidiophores long, cylindrical, stiffly upright, septate, verticillate and whorled or not. Conidiogenous cells holoblastic, proliferating sympodially, hyaline, thin-walled. Conidia elongate falcate or filiform (adapted from Maharachchikumbura et al. 2016b).

Notes: Jaklitsch & Voglmayr (2012) showed that Melogrammataceae clustered in Xylariales rather than Diaporthales based on analysis of ITS and LSU sequence data. Maharachchikumbura et al. (2015, 2016b) confirmed the placement of Melogramma in Melogrammataceae in Xylariales based on the analyses of combined LSU, SSU, tef1 and rpb2 sequence data. However, Senanayake et al. (2015) showed it should be placed in Amphisphaeriales. Hongsanan et al. (2017) confirmed the status in Amphisphaeriales based on phylogenetic and MCC trees.

Type genus: Melogramma Fr.
