Saprobic, endophytic or pathogenic on leaves, seeds and soil. Sexual morph: Stromata present or absent. Ascomata perithecial. Asci 8-spored, cylindrical, oblong, clavate, with a J+, funnel-shaped, apical ring. Ascospores biseriate or uniseriate, hyaline to pale brown, fusoid, ellipsoid or oblong. Asexual morph: Coelomycetous. Conidiomata if present, sporodochial. Conidiophores solitary or aggregated, mono- or biverticillate. Conidiogenous cells solitary or in whorls, polyblastic, sympodial, denticulate, cylindrical often ampulliform, lageniform with elongated necks and minute annellides from percurrent proliferations, hyaline to pale brown. Conidia hyaline, lunate, oblong, fusiform or cylindrical, straight or curved, flattened at base. Chlamydospores if present, brown (adapted from Hernández-Restrepo et al. 2016b). 

Notes: Microdochiaceae was introduced by Hernández-Restrepo et al. (2016b) to accommodate the genera Microdochium, Idriella and Selenodriella based on LSU sequence data. In the phylogenetic analysis, the type of Microdochium (= Monographella) formed a distinct clade in Xylariales. Species belonging to Microdochiaceae are characterized by monographella-like sexual morphs and asexual morphs with polyblastic, sympodial or annellidic conidiogenous cells, and hyaline conidia without appendages (Hernández-Restrepo et al. 2016b). Combined multi-gene and divergence estimates have revealed that the family diverged around 79 MYA (Hyde et al. 2017a).

Type species: Microdochium Syd. & P. Syd.

Other accepted species: Species Fungorum – search Microdochiaceae.
