Slopeiomyces

Slopeiomyces cylindrosporus (D. Hornby, Slope, Gutter. & Sivan.) Klaubauf, Lebrun & Crous, Stud. Mycol. 79: 103. 2014. (Type species).

Ascomata perithecial, superficial, globose, black, solitary to gregarious, 290–565 μm diam with a cylindrical, black neck, up to 242 μm long, 48–116 μm wide at base. Ascomatal wall up to 54 μm thick. Paraphyses unbranched, septate, hyaline. Asci 8-spored, unitunicate, clavate, straight to curved, 65–135 × 9–16 μm, with a refractive apical ring. Ascospores cylindrical, fusoid, to sigmoid, 3–8-septate, slightly curved, hyaline, 37–69 × 3.2–5.6 μm. Asexual state phialophora-like. Conidiogenous cells phialidic, subcylindrical to ampulliform, straight or curved, 6.3–19.6 × 2.4–4.2 μm, hyaline, with a flared collarette. Conidia ellipsoidal, fusiform, cylindrical to lunate, straight to curved, aseptate, hyaline, 2.9–6.3 × 0.7–2 μm (Description from Hornby et al., 1977).
