Acremonium spp. | Macro: rapid grower, white, cottony. |
Fusarium spp. | Macro: rapid grower; woolly to cottony, flat, spreading colonies; front-white, cream, tan, salmon, cinnamon, yellow, red, violet, pink; reverse-colorless, tan, red, dark purple, brown. |
Fusarium spp. | Micro: Macroconidia - 2 or more celled, thick-walled, smooth, cylindrical or sickle shaped (canoes) |
Geotrichum spp. | Macro: Rapidly growing, white, dry, powdery to cottony colonies, resemble ground glass, may be yeast-like, optimal growth at 25C, don't grow or grow weakly at 37C |
Geotrichum spp. | Micro: Arthroconidia that are rectangular or rounded at ends, don't alternate with "normal cells"; coarse true hyphae; no blastoconidia, conidiophores, or pseudohyphae |
Paecilomyces spp. | Macro: Rapid grower; flat, powdery, or velvety colonies initially white - turn yellow, yellow-green, olive-brown, pink, violet; reverse is dirty white, buff, brown |
Paecilomyces spp. | Septate, hyaline hyphae; conidiophores often branched; phialides swollen at bases and taper at apices; usually in pairs or brush-like clusters; conidia are unicellular, hyaline to darkly colored, in long chains |
Penicillium spp. | Macro: Rapid growing, velvety, woolly, or cottony colonies; initially white, become blue-green, gray-green, olive-gray, yellow, pinkish; reverse is usually pale to yellowish |
Penicillium spp. | Micro: Flask-shaped phialides, form brush-like clusters; conidia are round, unicellular, form unbranching chains at tips of phialides |
Scopulariopsis spp. | Macro: Moderate to rapid grower; granular to powdery colonies; front is white becoming light brown or buff; reverse is usually tan with brownish center |
Scopulariopsis spp. | Micro: Septate hyphae, conidiophores are hyphae-like and simple or branched |
Acremonium spp. | Micro: hyaline, septate hyphae; unbranched, solitary erect phialides formed directly on hyphal tips; conidia in clusters or fragile chains |
