ABSTRACT
Ramichloridium brasilianum colonies are slow-growing, reaching a diameter of 6 mm after 14 days at 24°C on MEA, and appear velvety to hairy, with entire margin; surface is dark olivaceous-gray; black gelatinous exudate droplets produced on oatmeal agar (OA). Submerged hyphae (1.5-2 μm wide) are pale olivaceous, smooth or slightly rough; aerial hyphae are olivaceous, smooth or rough, narrower and darker than the submerged hyphae. Conidiophores (2-2.5 μm × 70 μm) are unbranched, arising vertically from creeping aerial hyphae, straight or ¼exuose, dark brown, with up to 10 additional septa, thick walled, and cylindrical. Conidiogenous cells (10-30 μm long) are integrated, terminal, proliferating sympodially, giving rise to a long, straight rachis with crowded, slightly darkened minute scars (about 0.5 μm in diameter). Conidia (4-8.5 μm × 2-3 μm) are solitary, obovoid to fusiform with the widest part below the middle, thin walled, verruculose, aseptate, pale brown, slightly rounded at the apex, truncated at the base, with a slightly thickened and darkened hilum (1-1.5 μm in diameter) [7,8].
