Morphological characteristics
Colony colour : Green after sporulation
Colony characteristics : Uniformly dispersed, not pustulate or in conflict,sharply delimited and more or less dense central disk within which most conidia form
Colony radius : 42-60mm
Colony on PDA :Colony radius after 72 hrs. at 250C was 42-60 mm, at 350C, 0.3-8.3 mm
Hyphae : White hyphae, sharply delimited and with a more or less dense central disk within which most conidia form.
Mycelia :Uniform mat like formation
Pigments : No pigment diffusing into the agar
Odour : Sweet (coconut) odor typically noticed
Microscopic characteristics
Conidiophore : Conidiophores branching typically unilateral although paired branches are common. Branches typically arising at 900 or less with respect to the branch above the point of branching. Paired branching systems common.
Phialides : (4.2-) 6.0-9.7 (-15.0)μm long, (L/W (1.1-) 1.8-3.5 (6.3), straight or sinous, sometimes hooked, whorls of 2-4, often cylindrical and narror neck.
Conidia : Conidia subglobose to ovoidal, smooth, L/W = (0.8-)1.0-1.3(-1.6), green colour
Chlamydospores : Chlamydospores abundant within 7 d, globose to subglobose, terminal or intercalary, (5.2-)8.5-12.0(-16.3) μm diam.
Stromata : Solitary to gregarious, adjacent stromata often fused, (0.5) 0.9-2.4 (-7.0) mm diameter
Ascospores : Dimorphic, hyaline, thick walled, finely spinulose, distal part globose to subglobose
General characteristics
Main cell wall composition : Glucans, glycoprotien, chitin
Type of reproduction : Asexual (Herman et al. 2004).
Growth rate : Green conidia typically appearing within 57-66 hrs. on PDA at 300C in darkness.
Economic importance : Biological control against plant pathogens
Optimum temp. for growth rate : 25 - 300C
Optimum pH : 4.00 (Kredics et al. 2003).
