Index Fungorum number: IF556626; Facesoffungi number: FoF 06237
Etymology: — The specific epithet refers to the host ( Vespula , Hymenoptera ).
Holotype: — GACP2017079
Sexual morph: — Host 1.5–2 × 0.5–1 cm, brown. Stromata 3–7 cm long, 0.3–1 mm diam., single or double, stipitate, unbranched or branched into 2 fertile heads, arising from the head and thorax of insect. Stipe 2–6.5 cm long, 0.3–0.5 mm diam., yellow, fibrous, cylindrical, often flexuous, with a fertile apex. Fertile head 0.5–1 cm long, 0.5–1 mm diam., single, cylindrical or elliptical, pale yellow. Ascomata 520–720 × 200–380 μm (= 596 × 260 µm, n = 30), immersed, pale to yellowish, elongated flask-shaped. Asci 320–570 × 5.3–7.5 μm (= 454 × 5.8 µm, n = 60), narrow cylindrical, apex thickened, hyaline; apical cap 6.2–7.9 × 3.4–5.4 μm (= 7.0 × 4.0 µm, n = 60), hyaline. Ascospores almost as long as asci, filiform, hyaline, easily breaking into part-spores. Secondary ascospores 7.5–11.5 × 1.5–3 μm (= 9.1 × 2.1 µm, n = 90), fusiform, hyaline, smooth. Asexual morph: — undetermined.
Culture characteristics:— on PDA reaching 5 cm diam. after 6 weeks at 25 °C, superficial cottony, white, reverse yellow; after 10 weeks at 25 °C, reaching 6 mm diam., no conidia observed.
