Remarks (internal):Distinguished from other white-spored aspergilli by its (usually) biseriate, globose heads. Aspergillus candidus is a common species distributed mainly in tropical and sub-tropical regions. It has been reported from soils, flour, dough products, nuts, dried fruits and various foodstuffs but it is predominantly found on stored grains and seeds. These include wheat, oats, barley, sorghum, corn, rice and ground nuts (Domsch & Gams, 1980, Pitt & Hocking, 1985). In addition it has been found in dung, nests, and damaged flue-cured tobacco (Domsch & Gams, 1980)

Colonies slow growing on CZ, but somewhat more rapid with the addition of 20% sucrose; on MEA growing faster and sporulating more densely. Sclerotia present in some strains, cream at first but becoming purple to black. Conidial heads white, globose, often splitting in age, sometimes appear wet or slimy, particularly in young or fresh cultures. Conidiophores hyaline to slightly yellow, smooth, some short, others up to 1 mm long, sometimes septate. Vesicle 17-35 um diam., globose to subglobose. Metulae 7-20 x 5-8 µm, club-shaped, inflated, covering entire vesicles, absent in small heads. Phialides 6-9 x 2-3 µm. Conidia globose to subglobose, hyaline, smooth-walled 2,5-3,5 µm diam.
Diseases: In Animals. Aspergillus candidus has caused various disorders in pigs (Moreau, 1974). There is some evidence that A. candidus might be toxic to chickens and rats (Maracas & Smalley, 1972) and that it can act as a pathogen to zoo animals and birds (Saez, 1961). In Insects. It has been found on dead bees (Batra et al., 1973). Aspergillus candidus is reported to produce citrinin but the first report of citrinin production by an Aspergillus confused A. niveus with A. candidus (Raper & Fennell, 1965). But several reports indicate that it does produce citrinin (Ciegler, 1973).
Toxin production: In addition it produces kojic acid and candidulin (Kinoshita & Shikata, 1965), terphenyllin and
xanthoascin (Frisvad, 1988), and ß-nitropropionic acid (Kinoshita et al., 1968).
Geographical distribution: Worldwide.
