Tilachlidium Preuss, Linnaea 24: 126 (1851)
Hypocreomycetidae, Hypocreales, Tilachlidiaceae, Tilachlidium
Saprobic on dead fungi or hyperparasitic on living entomogenous fungi. Sexual morph: Undetermined. Asexual morph: Conidiophores synnematous. Synnemata simple or branched, cylindrical, tapering towards the apex, containing of bundles of parallel, longitudinally arranged, usually closely comp- acted hyphae. Conidiogenous cells phialidic, scattered, subulate, gradually tapering to an acute apex, hyaline, terminating hyphal cells of the synnema, or as lateral cells of the hyphae, arrange singly or in groups. Conidia hyaline, ellipsoidal to oblong, aseptate, smooth, covered by a mucoid sheath, aggregating into large sphaerical or irregular masses (adapted from Lombard et al. 2015, Maharachchikumbura et al. 2016).
Type species: Tilachlidium brachiatum (Batsch) Petch, in Ellis, Trans. Norfolk Norw. Nat. Soc. 15: 198 (1941)
Notes: Tilachlidium pinnatum was synonymised under T. brachiatum by Lombard et al. (2015). There are no records
for the sexual morphs of Tilachlidium. Species of Tilachlidium are saprobic growing on dried fungi or entomogenous on lepidopterous insects (Mains 1951). Sequence data are available only for the type species, T. brachiatum, in GenBank.
