A saxicolous species of Chiodecton and two corticolous species of Enterographa are described as new to science. Chiodecton submontanum is characterized by a saxicolous habitat, irregularly verrucose thallus, inspersed hymenium, ascospores usually exceeding 50 μm in length with 6–10 septa and the presence of roccellic acid. Enterographa sparrii has immersed, perithecioid ascomata in indistinct to slightly raised pseudostromata, 40–55 μm long ascospores with 6–9 septa and contains roccellic acid. Enterographa subcaudata has immersed, more or less round ascomata with a black disc, 35–58 μm long ascospores with 6–12(–15) septa and schizopeltic acid in its chemistry. Additionally, an identification key to the members of Roccellaceae reported so far from India is provided. Uttarakhand, Western Himalaya, lichenized fungi
