Paratrimmatostroma kunmingensis

Paratrimmatostroma kunmingensis Jayasiri, Phookamsak, D.J. Bhat & K.D. Hyde [as 'kunmingensis'], in Phookamsak et al., Fungal Diversity: 10.1007/s13225-019-00421-w, [44] (2019) Index Fungorum number: 556152            Facesoffungi number: 04961


Sexual morph: Undetermined. Asexual morph:  Hyphomycetous. Sporodochia effuse or confluent, visible as black powdery, superficial mass on host substrate, flattened, light brown, with a membranous base, composed of pseudoparenchymatous cells of textura angularis. Mycelium immersed, composed of septate, pale brown, branched hyphae. Conidiophores (6–)15–30(–50) × 2–4 µm (x̄ = 19.2 × 3.2 µm, n = 20), macronematous or semi-macronematous, mononematous, prostrate, or erect, usually short, oblong to cylindrical, straight or flexuous, arising as lateral branches from creeping hyphae, septate, branched or unbranched, slightly constricted at the septa so as to give a monilioid appearance, pale brown, smooth-walled. Conidiogenous cells 3–10(–15) × 2–4.5 µlm (x̄ = 7.1 × 3.1 µm, n = 30), holoblastic, mono- to polyblastic, integrated, terminal, brown, smooth-walled. Conidia solitary, acropleurogenous, dark brown, paler at the apical cell, branched, straight or flexuous, variable in shape, helicoid [(8–)10–20(–27) × (6–)10–20 µm (x̄ = 16.8 × 13.7 µm, n = 40)], cylindrical to sigmoid, or reniform [(8.5–)15–50 × 6–8(–10) µm (x̄ = 29.7 × 7.7 µm, n = 50)], solitary, tapering near apex and base, rounded at tip, multi-septate, 6–13-septate at maturity, constricted at the septa, smooth and thick-walled.
