Sporothrix ganodermatis Jing Z. Sun, Xing Z. Liu & K.D. Hyde, Asian Journal of Mycology 2(1): 152 (2019)

MycoBank number: MB827518

Facesoffungi number: FOF 06028

 

Fungicolous, growing on the fruiting body of Ganoderma lucidum. Asexual morph: Hyphomycetous. Conidiomata synnematous, scattered, dark brown to blackish. Synnemata, 700–1150 × 15–45 μm (x̅ = 1000 × 25 μm, n = 10), determinate, erect, straight, composed of tightly adpressed filaments, forming a firm subcylindrical, dark brown stipe, broadly rounded at base, with a tight capitulum, with apically divergent conidiophores. Conidiophores 2–3 μm (x̅ = 2.5 μm, n = 10) wide, individually filiform, unbranched, pluriseptate, dark brown below and pale brown to hyaline above, smooth. Conidiogenous cells mono- to polyblastic, sympodial, integrated, terminal, hyaline, and smooth-walled, 6–8 × 2–3 μm (x̅ = 7 × 2.5 μm, n = 30). Conidia acrogenous, hyaline, simple, aseptate, smooth, clavate to fusiform, 6–7.5 × 1.5–2.5 μm (x̅ = 7.2 × 2.1 μm, n = 30). Sexual morph: Ascomata 100–120 μm diam., formed on host fruiting body, with bases black or dark-brown, globose. Ascomatal necks smooth, dark, straight or slightly curved, tapering at apex. Asci evanescent. Ascospores hyline, simple, aseptate, smooth, cylindrical, clavate, mostly curved, 3.5–7 × 1.2–1.5 μm (x̅ = 4.2 × 1.3 μm, n = 30). (Description from Sun et al. 2019)
