Description

Facesoffungi number: FoF 10474

Sexual morph (Fig. 1 ): Host: a bat moth larva ( Lepidoptera , Hepialidae ), 3.5-4.8 cm long, greyish to light yellow. Stromata: 4-6 cm long, 0.3-0.5 cm wide, arising from the head of host, clavate, solitary. Stipe: cylindrical, greyish to light yellow, fleshy, glabrous, enlarging abruptly at fertile portion. Fertile head: 1.5-2.1 cm long, 0.4-0.6 cm wide, grey white to dark grey, different from the stipe, without sterile tip. Ascomata: 320-580 × 110-230 μm (442 × 186 μm, n = 30), flask-shaped, immersed. Asci: 140-230 × 5-7 μm (183 × 6 μm, n = 30), narrowly cylindrical, 8-spored, hyaline, with a thick apical cap. Apical cap: 5-7 μm (6 μm, n = 30). Ascospores as long as asci, hyaline, filiform, smooth, irregularly breaking into secondary spores. Secondary spores: 2-9 × 1-2 μm (5.5 × 1.5 μm, n = 30), cylindrical, hyaline, irregular length.

Asexual morph (Fig. 2 ): Colonies on Czapek agar: attaining a diameter of 2-3 cm within 14 d at 25°C, dense, flat, velvety, white. α-phialides: 13-24 × 1-2 μm (18 × 1.5 μm, n = 30), hyaline, Hirsutella -like smooth, solitary, mostly arising from aerial hyphae, slender, with a short neck. β-phalides: 28-45 × 1-2 μm (36 × 1.5 μm, n = 30), hyaline, smooth, slender, Acremonium -like, mostly solitary. α-conidia: 3-5 × 1-3 μm (4.5 μm, n = 30), subglobose, one-celled, smooth, hyaline. β-conidia: 6-10 × 1-3 μm (8 × 2 μm, n = 30), fusiform, with both ends sharp, one-celled, smooth.

Host: On larvae of a bat moth ( Lepidoptera , Hepialidae ) living in soil.

Etymology

Referring to the shape of the stroma.

Distribution

Thus far only known from China.
