Etymology:— Refers to India, the country of origin.

Holotype:— HCIO 52049 .

Colonies on natural substrate effuse, hairy, dark brown, on MEA white when young, becoming red with age, woolly, attaining a diam. of 3–3.2 cm in 10 days; mycelium partly superficial, partly immersed in the host tissue, composed of brown, smooth, branched, thin-walled, 1.5–3 μm wide hyphae. Conidiophores macronematous, mononematous, unbranched, septate, erect, straight to flexuous, smooth, thick-walled, dark brown, 150–685 × 5–10 μm. Conidiogenous cells polyblastic, terminal at first, later becoming intercalary, sympodial, 40–60 × 5–8.5 μm. Conidia solitary, dry, acropleurogenous, brown, thin-walled, rounded at apex, pointed at base, slightly curved, minutely verruculose, 5–7 transeverse septate, rarely 3-septate, sometimes with 1 longitudinal septum, 35–42 × 13–15 μm, formed as a blown-out end, at first with a very narrow isthmus between the conidiophore apex and young conidium.
