Ernakulamia Subram., Kavaka 22/23: 67 (1994).

Index Fungorum number:IF 28737;Facesoffungi number:FoF 06667,3morphological species (Species Fungorum 2022), 3 species with molecular data.

Saprobic on host.Sexual morph: Unknown.Asexual morph:Colonies on natural substrate effuse, black.Conidiophores andconidiogenous cells not seen.Conidia variable in shape, subglobose, obconical, broadly ellipsoidal to broadly pyriform, muriform, dark brown to blackish brown, verrucose at the base where a pore is often seen, internally filled with a mass of hyaline, septate, hyphae sometimes with swollen cells up to 5 μm wide, appendiculate, with 3–13 cylindrical, straight or flexuous, septate, brown, smooth appendages, up to 132 μm long, 3–5 μm wide, 4.5–7 μm wide at base, 2–3 μm wide at the apex (adapted from Delgado et al. 2017).

Type species:Ernakulamia cochinensis(Subram.) Subram.

Notes:Ernakulamiais characterized by erect, short, cylindrical, conidiophores, conidia of variable shapes and sizes with appendages (Subramanian 1957a).Ernakulamia cochinensis was previously known asPetrakia cochinensis Subram. (Subramanian 1957a). Ellis (1976) transferredPetrakia cochinensis toPiricauda.Subramanian (1957a) transferredPiricauda cochinensis toErnakulamia. Delgado et al. (2017) provided sequence data forE. cochinensis and placedErnakulamia inTetraplosphaeriaceae. Jayasiri et al. (2019) introduced the second species,E. krabiensis from decaying pods ofAcacia sp. in Thailand. Hyde et al. (2020b) added the third species,E. tanakae from a decaying spathe ofCocos nucifera based on morphology and phylogeny. Molecular markers available for the genus are ITS, LSU, TUB2 and RPB2. Recent literature: Boonmee et al. (2021), Tian et al. (2024).
