Holotype:
JAPAN.
Habitat:
Leaf litter, underside of leaf.
Host:
Spiders.
Description:
Host covered with dense weft of pink mycelia, showing a velvety appearance. In early stages the mycelia coming out of the joints in the legs and body eventually fully covered with layers of conidiophores. Conidiophores mononematous or (rarely) synnematous, 100–150 × 2–2.5 μm. Phialides borne on the conidiophore or on small side branches, 5–7 × 2–3 μm. Conidia purple-grey, variable in size and shape within individual specimens, 3.5–6 × 1–1.5 μm. Stroma arising from head of host, 50–2 mm, composed of a simple stipe and clavate fertile part, cream white. Mycelia covering the whole body of host. Perithecia immersed, elongated flask-shaped, 1000–1300 × 200–300 μm, with the ostioles. Asci filiform, hyaline, 570–800 × 4.5–5.5 μm. Ascospores filiform, hyaline, multi-septate, easily breaking into part-spores. Part-spores 3–4 ×1–1.5 μm, cylindrical with truncate ends.
Culture characteristics:
Colonies on PDA attaining a diam of 10 mm in 14 d. Colonies are floccose, white, changing to grayish-purple when conidial production starts.
