Description

Conidiophores 37-50 μm long (x̄ = 42.2 µm, SD = 4.6, n = 20), 5-6.8 µm wide (x̄ = 5.9 µm, SD = 0.6, n = 20), macronematous, mononematous, solitary, erect, unbranched, 1-3 septate. Conidiogenous cells 10-12 μm long (x̄ =10.8 µm, SD =0.5, n = 20), 4-5 μm long (x̄ = 4.8 µm, SD = 2.4, n = 20), monoblastic, integrated, terminal, dark brown. Conidia 36-52 μm long (x̄ = 36.6 µm, SD = 12.7, n = 20), 8-10 μm wide (x̄ = 9.4 µm, SD = 2.5, n = 20), acrogenous, solitary, clavate to broadly fusiform, 5-6 septate, with a short and hyaline rostrate tip at apex, brown, smooth-walled.

Notes

Wu (2005) firstly described this specis from China. Species similar to S. conversum , that produce conidia with barrel- to ampoule-shaped layers and inverted rod to spindle-shaped conidia include S. australiense M.B. Ellis, S. clarki P.M. Kirk, S. hamatum M.B. Ellis, S. pedunculatum (Peck) M.B. Ellis, S. rubi M. B. Ellis and S. uapacae M.B. Ellis ( Wu and Zhuang 2008). The difference between S. conversum and all these species is that the conidial apex in S. conversum has cap-like and conical mucinous appendages ( Wu and Zhuang 2008).
