Hypocrella luteola Hywel-Jones & Mongkols.

Specimens were found on the underside of dicotyledonous leaves of forest plants. Hosts are Hemiptera (scale insects). Stromata discoid to stud-shaped, up to 3 mm in diam., up to 2.5 mm high, pale yellow; conidiomatal ostioles sunken, dark yellow. When fresh it is covered by a copious mass of extruded, pale yellow conidia; pycnidia embedded in the stroma, laterally oval 300-400 μm high, 200-350 μm diam.; paraphyses present, linear, filiform, up to 300 μm long, up to 2 μm wide; conidiogenous cells phialidic up to 25 μm long, 1.5-2 μm wide; conidia fusoid, with acute ends 10-12.5 μm long, 2-2.5 μm wide. Conidia will germinate within 24 h on PDA. Colonies are slow-growing, attaining a diam. of 8 mm and producing conidia after ca. 4 wk on PDA at 20°C. Colonies dense by weft of yellowish mycelium, spore mass yellow spreading over the stroma, yellow crystals scattered in PDA with old cultures. Collections in Thailand have been from Doi Inthanon National Park in the far north until Khao Pu – Khao Ya National Park in the south. Collections have been made throughout the year.
