Summary:

Fruiting body: clavate [club-shaped], sometimes fused, branched or lobed, the upper part fertile and the lower part sterile, "fertile along all or most of stipe" [sic]; total height (0.5)2.5-4.5(8)cm, delineation between fertile and sterile parts sometimes evident, upper part golden yellow to a shade of brown, surface bald, sometimes wrinkled, perithecial elevations not evident or surface slightly bumpy, openings of ostioles visible as small dots against a pale yellow background
Stem: where sterile, white to beige, velvety or not; adjacent stems often appearing fused, with fissures demarcating individual stems
Microscopic: part-spores colorless, finely verrucose, dimorphic: a) distal part-spores (2.2)2.7-3.7(4.5) x (2.2)2.5-3.5(4.5) microns, round to nearly round, b) proximal part-spores (2.2)3.0-4.0(6.0) x (1.5)2.2-2.7(3.7) microns, nearly round to conic; asci [8-spored], (45)65-90(113) x (2.2)2.5-4.5(5.4) microns, cylindric, with slightly thickened apex
Habitat / Range
typically gregarious, single or sometimes fused, on barked but typically wet, rotten wood, and on wood chips
Similar Species
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).
