Morphological characteristics
Colony colour : Cool white fluorescent light producing more or less intense yellow pigment
Colony characteristics : Colonies uniformly flat and velvety
Colony radius : 40 - 75mm
Colony on PDA :Colony radius on PDA within one week was 40-75mm at the optimum temperature of 200C. No growth on PDA after 64 hrs. at 300C or 350C.
Hyphae : Hyphae in the form of a uniform lawn over the colony
Mycelia :Aerial mycelium comprising short hyphae in the form of a uniform lawn over the colony.
Pigments : Intense yellow pigment
Odour : No distinct odor detected
Microscopic characteristics
Conidiophore : Arising from the surface of the agar or from aerial hyphae, 50-100 μm long, smooth, typically branched along the length in a verticillate fashion.
Phialides : Divergent from point of attachment to the conidiophore, straight, tapering slightly from base to tip, 9-15 μm long, 2.5-3.9 μm wide in the middle, 2.5-3.0 μm wide at the base; periclinal thickening visible at the tip.
Conidia : Green, typically clavate to ellipsoidal or subglobose, often with a truncate or slightly protuberant base, 3.5-5 χ 2.5-3 μm, L/W 1.4-1.8, smooth, held in drops of pale green to colorless, watery liquid.
Chlamydospores : Chlamydospore produced abundantly, globose to subglobose.
Stromata : Solitary to gregarious, 1-5 mm diam circular to elliptic in outline, centrally but broadly attached, at first yellow but becoming slightly rufous with age
Ascospores : Green, more or less monomorphic and subglobose, thick walled, warted, distal part (2.5-)3.5-4.0 χ (3.0-)3.3-3.7(-4.07) μm, proximal part (2.8-)3.0-4.0(-5.0) χ (2.2-)2.7-3.7(-4.0) μm.
General characteristics
Main cell wall composition : Glucans, glycoprotien, chitin
Type of reproduction : Asexual (Herman et al. 2004).
Growth rate : Colony radius on PDA and malt extract agar (MEA) within one week 40-75 mm at the optimum temperature of 200C
Economic importance : Biological control against plant pathogens
Optimum temp. for growth rate : 200C
Optimum pH : 4.00 (Kredics et al. 2003).
