Acladium conspersum Link ex Pers.<br />

Symptoms on grain. Colonies are effuse, <strong>of</strong>ten very large, cottony and pale at first, later<br />

becoming velvety and fulvous or snuff-colored (Fig. 2).<br />

Morphology. Mycelium is mostly superficial. Conidiophores and hyphae have same<br />

thickness (6-9 μm), up to 350 μm long but usually shorter, and are subhyaline; cylindrical<br />

denticles are numerous especially on <strong>the</strong> upper part. Conidia are ellipsoidal, papillate at <strong>the</strong><br />

base, smooth, individually subhyaline or straw-colored, fulvous in mass, 15-20 (average 17)<br />

μm x 9-14 (average 12) μm (Fig. 3).<br />

Quick clue. Lemon-shaped conidia are present on <strong>the</strong> conidiophore.<br />

Importance. Acladium conspersum is very common on dead wood and bark <strong>of</strong> many different<br />

trees and shrubs in Canada, Europe including Great Britain, and USA. Occurrence <strong>of</strong> this<br />

fungus and also <strong>the</strong> method to kill <strong>the</strong> fungus adhering to <strong>the</strong> grains <strong>for</strong> its safe consumption<br />

has been reported on sorghum by Navi et al. (1997).<br />
