Holotype:
THAILAND, Narathiwat Province, Hala Bala Wildlife Sanctuaryk, 23 Aug. 2011, A. Khonsanit, holotype BBH 31089, ex-type living culture BCC 49409.
Habitat:
Underside of dicotyledonous leaves.
Host:
Whitefly nymphs (Hemiptera).
Description:
Sexual morph: stroma flattened pulvinate, white, 3-6 × 1-1.5 mm; tubercles arising from a thin pulvinate base, separated from one another and located at the margin of the stroma when conidiomata are present in the center. Tubercles cylindrical, 500-600 μm in height, 350-480 μm diam. Perithecia develop singly in a tubercle, flask-shaped, 300-550 μm in height, 250-300 μm diam. Asci cylindrical, 152-280 × 610 μm, with a cap approx. 4 μm thick. Ascospores disarticulating into part-spores inside the ascus which are narrowly cylindrical, slightly tapering towards the ends, 11-16 × 1.5-2.5 μm. Asexual morph: stroma white in fresh specimens, flattened pulvinate, very thin, surrounded by a hyaline hypothallus, 0.2-0.5 μm thick, 1-4 μm diam. Conidioma appearing as shallow depressions in the center of the stroma, forming a ring, 140-200 × 150-180 μm, globose, with yellowish white conidial masses. Conidiogenous cells cylindrical, up to 22 μm long, 1-2 μm wide. Conidia fusoid, tapering slightly toward the ends, 8-12 × 1.5-3 μm. No paraphyses observed.
Culture characteristics:
Colonies on PDA approx. 1 cm diam after 4 wk. The stromatic colonies were white, forming compact stromata. The cream-colored conidial masses produced a scattered covering over the surface of the stromatic colonies after 4 wk.
