Abstract

The present communication reports 12 new lichen species for the first time from the state of Andhra Pradesh. Many of them were foliose lichens while Chrysothrix chlorina, Diorygma junghuhnii and Hafellia curatellae are the only crustose forms. A brief description of the species and their distribution in India are provided for all the taxa. The checklist of 43 lichens so far reported from Andhra Pradesh is also provided. The study clearly indicates the enormous scope for lichenological investigations in the state and could act as baseline for future biomonitoring, bioprospection and biodiversity studies.

Abstract

Distribution of epiphytic lichens from three districts of Assam viz. Baksa, Kamrup and Sonitpur have been enumerated for the first time from eleven locations. A total of 67 species belonging to 12 families and 24 genera have been recorded. Of the total species, crustose, foliose and leprose lichens represented 60%, 39% and 1% respectively. The family Physciaceae emerged to be the most dominant, with a total of 20 species followed by Graphidaceae with 16 species.
