Lombard et al. (2016) erected Albifimbria to accomodate Myrothecium verrucaria (= Peziza verrucaria) and other three taxa that clustered distant to the Myrothecium s.str. clade in the phylogenetic analysis of cmdA, ITS, rpb2, tef1 and tub2 regions. Albifimbria species were isolated from soil, dead hardwood, leaf of Solanum tubersum and basidioma of a resupinate polypore (Lombard et al. 2016). The genus is characterized by sporodochial conidiomata or simple conidiophores. Simple conidiophores emerge directly from superficial hyphae and, are dolliform, reniform or allantoid, and hyaline with smooth-walls. Sporodochia are stromatic, superficial, cupulate to discoid, scattered to gregarious and oval to elongate or irregular in outline. A white fringe is surrounding the slimy masses of conidia, that are pale olivaceous green to dark green. Stroma are well-developed, hyaline and the cells forming a textura globulosa or textura angularis. Setae arise from the basal stroma between the conidiophores or from the white fringe. They are simple, unbranched, straight to circinate, septate and hyaline with thin and verrucose walls. Sporodochial conidiophores are macronematous, irregularly, penicillately or verticillately branched, hyaline and smooth-walled. Conidiogenous cells are phialidic, cylindrical to allantoid and hyaline with smooth walls. Conspicuous collarettes and periclinal thickenings are present. Conidia are aseptate, ellipsoidal to fusiform to limoniform to subglobose and hyaline. They have smooth walls and sometimes bearing funnel-shaped mucoid apical appendages. The sexual morph is undetermined (Lombard et al. 2016).
