Hypocrea leucopus (as Podostroma leucopus) was previously considered to be a synonym of Hypocrea alutacea. Hypocrea leucopus typically occurs on the ground and Hypocrea alutacea on wood. Hypocrea leucopus has a Verticillium-like anamorph and Hypocrea alutacea a Trichoderma-like one, but these are generally not found in nature. Hypocrea alutacea is somewhat browner (golden yellow to a shade of brown versus pale yellow to golden brown). Hypocrea truncata (Podostroma truncatum) has a more truncate fruitbody with depressed apex (Castellano). Podostroma zeylandicum lacks a stem and has slightly warted spores (Castellano).Habitat
