Holotype:
PAPUA NEW GUINEA, Keravat, 23 Mar. 1980, ex-type living culture CBS 610.80.
Habitat:
Underside of dicotyledonous leaves.
Host:
Spiders (Araneae; Theridiidae).
Description:
Spider hosts covered by light yellow to pale yellow mycelium. Sexual morph: Stromata stipitate, solitary or multiple. Stipes cylindrical, arising from the dorsal region of the host, white to pale yellow, 3-5 mm long, 0.5-1 mm broad. Fertile heads produce at the terminal of stipes, disc-shaped, upper surface slightly convex, 1-3 × 1-2 mm. Perithecia completely immersed, narrowly ovoid, 500-750 × 200-300 μm, ostioles strong orange yellow. Asci cylindrical, 8-spored, 350-450 μm long, 5-7 μm broad, with cap 3-5 μm thick. Ascospores hyaline, filiform, whole ascospores, 400-460 × 1-1.5 μm. Asexual morph: Synnemata multiple, cylindrical, occasionally acuminate apex, white, up to 8 mm long, 50-200 μm broad. Conidiogenous cells phialidic, scattered along with the synnemata. Phialides solitary, globose to subglobose, arising from the mycelium, 4-6 × 4-6 μm, with distinct necks, 0.5-1.5 × 0.5-1 μm. Conidia hyaline, fusoid or fusiform-elliptical, 2-10 × 1-2.5 μm.
Culture characteristics:
Colonies on PDA attaining a diam of 7–10 mm in 21 d, cottony with high mycelium density, white, moderate purplish-red to dark purplish-pink pigment diffusing in the medium, reverse moderate red. Sporulation observed after 30 d with absence of synnemata. Phialides arising from aerial hyphae, solitary, mostly globose to subglobose, occasionally cylindrical, 4–5 × 2–5 μm, distinct necks, 0.5–2 × 0.5–1 μm. Conidia hyaline, fusoid, fusiform-elliptical, cylindrical, 2–11 × 1–3 μm.
