Colonies effuse, dark brown or black; mycelium immersed or sometimes partly superficial, irregularly branched, brown. Stroma sometimes developed but absent in most species. Setae and hyphopodia absent. Conidiophores macronematous, mononematous, erect, unbranched in most species but branched several times, particularly towards the base, in others, septate, pale to dark brown, smooth-walled, thick-walled but the wall somewhat unequal in thickness due to the method of proliferation, lacking a specialized foot cell. Conidiogenous cells monoblastic, inte- grated, terminal, usually percurrently proliferating (often many times) with the proliferation occurring from the distal septum of the penultimate cell of the conidiophore (or its successive proliferations). Conidia usually solitary, dry, acrogenous, rather variable in shape but mostly ellipsoid to clavate, pale to dark brown, the cells often unequally pigmented, 1-5 septate, smooth- walled or rarely slightly verrucose, each septum generally with a central pore, the base truncate and with a small portion of the conidiogenous cell adhering as a short frill in most species. Type species: Endophiagmiella pallescens B. Sutton. Number of species: Four species were accepted by Ellis (1976 : 143-145) but several have been recognized since and many taxa formerly placed in the genus Endophragmia Duvernoy & Maire are currently being transferred to it by Hughes (unpublished), so that the actual number of species in the genus is about 30. Most species are saprophytes but some appear specific to parti- cular Please note that these images are extracted from sca
