Two corticolous species of Coenogonium viz., C. pseudonepalense and C. submoniliforme are described as new to science. Coenogonium pseudonepalense is characterized by a crustose, greenish‐grey thallus, pale‐orange apothecial disc and 13.0–17.0 × 2.5–3.0 µm ascospores. Coenogonium submoniliforme is characterized by appressed‐filamentous thallus, small‐sized apothecia (up to 0.4 mm in diameter), pale orange apothecial disc and 14.0–18.0 × 2.8–3.8 µm ascospores. Coenogonium lueckingii and C. pineti are new records for Indian lichen biota. An updated world key to the known species of Coenogonium is also provided. [ABSTRACT FROM AUTHOR]
