Description

Conidiophores 110-140 μm long (x̅ = 127.9 μm, SD =10, n = 20), 2.5-4.5 µm wide (x̅ = 2.9 μm, SD = 1.9, n = 20), macronematous, mononematous, single, unbranched, erect, straight or flexuous, septate, smooth, brown. Conidiogenous cells 12-13 μm long (x̅ = 12.4 μm, SD =0.34, n = 20), 3-4 µm wide (x̅ = 2.9 μm, SD = 0.4, n = 20), monoblastic, integrated, terminal, cylindrical, smooth, brown, percurrently proliferating. Conidia 12-17 μm long (x̅ = 14.1 μm, SD = 2.8, n = 20), 2-5 µm wide (x̅ = 3.4 μm, SD = 1.1, n = 20) holoblastic, solitary, acrogenous, dry, clavate, smooth, lower two cells brown, apical cell pale brown, 2-septate.

Notes

Delgado et al. (2007) originally described this species on the stems of dead liana in Cuba and later Ma (2012) discovered it on dead branches in China. It superficially resembles Hemicorynespora fusispora , but the latter has spindle to inverted rods and longer conidia (12-20 µm vs. 15-30 µm) and its conidiogenous cells are shorter than those of H. clavata (12.5-21 vs. 15-18 µm) ( Delgado et al. 2007).
