Distinctive macro and micromorphological features of the studied Aspergillus isolates.

Section Macro- and Micromorphological Characteristics
Versicolores Colony on CYA, 25 °C, 7 days: Variable coloration, greenish, turquoise, yellowish, and radially sulcate; velutinous texture; tawny olive to orange cinnamon reverse, vinaceous or brown or scarlet; moderate to abundant exudate, clear to yellowish to reddish-brown, reddish-brown soluble pigment. Biseriate conidial heads, radiate, globose to subglobose conidia, rough to prickly.
Usti Colony on CYA, 25 °C, 7 days: Blond/greyish-yellow; floccose texture; yellow reverse with a beige center. Biseriate, predominantly pyriform vesicles, globose conidia, very rough ornamentation, with an inner and outer visible wall.
Flavi Colony on CYA, 25 °C, 7 days: Green olive, brown olive, greenish-brown, brownish yellow; woolly or floccose texture; colorless, light brown or orange reverse. Presence of brown sclerotia in some isolates. Biseriate and uniseriate conidial heads, radiated to columnar; rough, colorless stipe, globose to ellipsoidal conidia, rough in some isolates.
Aspergillus Colony on CYA, 25 °C, 7 days: Sulfur yellow mycelium; floccose texture; luteous to ochreous reverse. Uniseriate conidial heads, Ascomata Eurotium-like, cleistothecial, superficial, yellow, globose to subglobose. Ascospores hyaline, globose to subglobose in surface view.
Cremei Colony on CYA, 25 °C, 7 days: Greyish-yellow, smooth texture; brownish-cream reverse. Biseriate, radiated conidial heads separated into columns, smooth and colorless wall stipe, globose or subglobose conidia, smooth to rough.
Fumigati Colony on CYA, 25 °C, 7 days: Greyish-turquoise; velutinous texture; creamy reverse. Uniseriate, predominantly pyriform vesicles, grey to blue-green conidia.
Clavati Colony on CYA, 25 °C, 7 days: Blue-green or pale blue-green; velvety texture; uncolored or dull tan reverse. Presence of exudates in some isolates but no soluble pigments. Uniseriate conidiophores with blue-green conidia, hyaline conidiophore stipes, and clavate aspergilla.
Nigri Colony on CYA, 25 °C, 7 days: Brown to black; floccose texture, sulcate; beige to cream-yellow, brown, dark grey, uncolored to yellow reverse. Uniseriate or biseriate, spherical vesicles, smooth stipes, rough dark globose, finely rough, or finely spiny conidia.
Candidi Colony on CYA, 25 °C, 7 days: Light cream; submerged texture; light brown reverse. Biseriate conidial heads, radiate, thick-walled conidiophores, septate, elongated vesicles, small conidia globose to subglobose, slightly roughened.
Flavipedes Colony on CYA, 25 °C, 7 days: Yellowish white; floccose surface texture; brown to dark brown reverse. Biseriate conidiophores, radiate, elongated or subglobose vesicles, globose to subglobose conidia, smooth to finely roughened.
Circumdati Colony on CYA, 25 °C, 7 days: Yellow to ochre colonies, cream, or pale yellow; smooth texture; yellow, orange, or cream reverse. Presence of pink to purple-brown sclerotia in some isolates. Predominantly biseriate, rough stems, smooth or finely rough globose conidia.
