Identifies new lichen species and records in India, suggesting biodiversity expansion.
The present study deals with a new species of saxicolous crustose lichen Thelopsis indica and two new records of corticolous crustose lichens named as Cryptothecia nigeriensis and Fissurina varieseptata from India. The new species of Thelopsis was collected from Horhap forest of Jharkhand, India. It is diagnosed as epilithic, smooth, areolate thallus c. 0.1–0.8 mm across, ascomata on thalline warts, 1–2 sunken ostioles, paraphysoids reticulately branched and anastomosing, ascospores 1‐septate, c. 5–6 × 2.5–2.75 μm, halonate. Cryptothecia nigeriensis and Fissurina varieseptata were collected from West Bengal, India. The species were identified and described on the basis of morpho‐anatomical and phytochemical parameters.
