Holotype:
THAILAND, Chanthaburi Province, Khao Yai National Park, 17 Dec. 2014, A. Bootkot, A. Khonsanit, W. Noisripoom, D. Thanakitpipattana, B. Sakolrak, holotype BBH 40785, extype living culture BCC 80047.
Habitat:
Undersides of Durian leaves.
Host:
Scale insects (Hemiptera).
Description:
Stromata pulvinate, greyish yellow, up to 2-3 mm diam. 
Indeterminate synnemata in numbers of 2-30, formed on stromata, up to 800 μm long, 100-120 μm wide. 
Entire phialides (hirsutella-like) emerging laterally of synnemata, subulate, 12-20, basal part 7-15 × 3-4 μm; attenuated helical neck 5-8 × 1.5 μm. 
Conidia hyaline, fusoid, 10-12 × 3-4 μm, aseptate. Colour change of stromata and synnemata in 3% KOH not observed.
Culture characteristics:
Colonies on PDA attaining a diam of 0.5 cm diam in 2 wk at 25 °C, aerial mycelium greyish orange forming a compact, somewhat stromatic felt. Conidial masses vivid yellow, covering stromatic colonies at 2 weeks. Phialides (hirsutella-like) formed laterally by hyphae, appearing yellowish because of cell content, entire phialides 12–20 × 3–4 μm, hyaline, helical necks present, up to 10 μm long. Conidia fusoid to cylindrical, hyaline, aseptate, smooth-walled, 8–15 × 3–4 μm.
