Saprobic on submerged bamboo or dead wood. Sexual morph: Ascostromata solitary to gregarious, erumpent to superficial, visible as dull, black, dark at the basal region and orange brown at the apex, conical to lenticular, with a flattened base, uni- to bi-loculate, glabrous, coriaceous, ostiolate, with pore-like opening. Peridium thick-walled, of unequal thickness, poorly developed at the base, composed of several layers of dark, pseudoparenchymatous cells, with fungal tissue intermixed with the host cells. Pseudoparaphyses dense, trabeculate, filiform, hyaline, septate. Asci 8-spored, bitunicate, fissitunicate, clavate to cylindric-clavate, short pedicellate, apically rounded with well-developed ocular chamber. Ascospores uni- to bi-seriate, fusiform, hyaline, becoming brown when released from asci, septate, smooth-walled, with or without mucilaginous sheath (Liu et al. 2015). Asexual morph: Undetermined.
Notes: Flammeascoma was introduced to accommodate F. bambusae, which was collected from submerged bamboo (Liu et al. 2015). Flammeascoma is similar to familial type Anteaglonium Mugambi & Huhndorf in the shape of asci and ascospores (Mugambi and Huhndorf 2009, Liu et al. 2015). However, Flammeascoma is unique in producing reddish orange pigmentation at the apex of ascostromata, while Anteaglonium lacks this character and always sits on a thin darkened crust with or without sparse, dark brown, septate subiculum (Mugambi and Huhndorf 2009; Ariyawansa et al. 2015; Liu et al. 2015).
Flammeascoma appears to be polyphyletic as F. bambusae (type) clusters with Anteaglonium gordoniae Jayasiri et al. and F. lignicola Boonmee & K.D. Hyde clusters with our new genus Purpureofaciens, but without bootstrap support More species are expected to clarify whether Flammeascoma is polyphyletic.
