Habitat:
Buried in the ground.
Host:
Larva of Oxynopterus sp. (Coleoptera).
Description:
Stromata two to several, simple, cylindrical to clavate, branched, up to 3.5 cm long, 3-5 mm wide. Rhizoids flexuous, arising from the region between head and thorax of Coleoptera larva buried ca 6-7 cm deep under the ground. Upper part of the stromata fertile, yellow to greyish green, 2.5 cm long, 3-5 mm wide. Perithecia immersed, oblique in arrangement with slightly protuberant ostioles, flask-shaped, 600-700 × 210-290 μm. Asci cylindrical, 8-spored, up to 420 μm long, 5-6 μm wide, apical cap prominent, 3-4 × 4 μm. Ascospores filiform, with septa but do not dissociate into part-spores, 224-420 × 1-1.5 μm. Asexual morph not seen in nature.
Culture characteristics:
Colonies on PDA attaining a diam of 15 mm in 21 d, dense white mycelium, fluffy, entire edge, white turning to leaf green in the centre of colonies due to production of conidia. Sporulation starts at 21 d after inoculation. Conidiophores terminating in branches, with 2–3 phialides per branch, forming a palisade-like layer. Phialides cylindrical with semi-papillate apices, 5–9 × 1.5–3 μm. Conidia smooth-walled, leaf green, cylindrical with rounded apices, 4–7 × 2–3 μm.
