Holotype:
THAILAND, Chiang Mai Province, Ban Huathung community forest, 5 Oct. 2012, K. Tasanathai, A. Khonsanit, W. Noisripoom, P. Srikitikulchai, R. Promharn, holotype BBH 32918, ex-type living culture BCC 56802.
Habitat:
Underside of a dicotyledonous leaf.
Host:
On Araneida.
Description:
Spiders totally covered by the white to cream mycelial mat. A single 
synnema or synnemata in pairs cream to light brown, often darker than the mycelia covering the host, narrowing toward the apex and terminating in a swollen sterile tip with acute apex. 
Conidiophores arising laterally from the outer layer of synnemata, crowded, 23–83 × 4–7.5 µm, mostly verrucose, occasionally slightly roughed for very short conidiophores, abruptly narrowing to a slender apex and forming a globose to subglobose vesicle. Vesicles 6–8 µm in diam, each bearing a number of metulae. Metulae obovoid to broadly obovoid, 7–10 × 4.5–6 µm. 
Phialides borne on metulae, narrowly obovoid, 7–10 × 2–3 µm bearing fusiform to broadly fusiform conidia, 3.5–6 × 1.5–2.5 µm. 
Conidial heads spherical, 31–37 µm in diam. 
Perithecia mostly appearing in pairs, ovoid, superficial with a loose covering of white to cream mycelia, reddish yellow, up to 1,000 µm in length, 320–350 µm in width. Asci 600–700 × 7–8 µm. Ascospores often disarticulating into part-spores. Part-spores fusiform, 12–15 × 2–3 µm. Granulomanus-like asexual morph absent.
Culture characteristics:
Colonies on PDA slow-growing, attaining a diam of 1 cm in 20 days at 25 °C, white, velvety; reverse cream, becoming light brown with age toward center.
