K., Mishra G. K. & Nayaka S. 2013. New records of lichen genus Agonimia and Baeomyces (Ascomycota) from India. Geophytology 43(1): 00-00. Agonimia tristicula (Nyl.) Zahlbr. and Baeomyces carneus (Retz.) Flörke, two squamulose lichens, are described as new records for Indian lichen biota. Both the species are collected from eastern Himalayas in Arunachal Pradesh. Genus Agonimia is also a new record for India. Key Words: Lichenized fungi, Agonimia, Baeomyces, taxonomy, Arunachal Pradesh. INTRODUCTION Eastern Himalayan region has a unique topography and climate which supports luxuriance and abundance of different plant groups in the area including lichens. Out of the seven sister states of north eastern India, the state of Arunachal Pradesh is bestowed with peculiar lichen diversity having more affinities with the Sino- Japanese elements. Owing to the difficult and remote terrains the lichen flora of most of the districts are not explored so far. Recently the lichen explorations in some districts of the state were carried out which resulted in the discovery of new or otherwise interesting lichens taxa from the state by Ahti & Upreti (2004), Singh et al. (2005), Dubey et al. (2007) and Singh & Singh (2012). In the present study two squamulose lichens are described from the state as new records for the Indian lichen flora. MATERIAL AND METHOD The specimens are examined morphologically, anatomically and chemically. The morphological studies were carried out with the help of Leica stereo zoom microscope E24. The anatomical details were studied in thin hand-cut sections of apothecia and thallus mounted in water, cotton blue, 5% KOH and Iodine were used for the hamathecial reactions and observed under a compound microscope (LECIA DM 500). The chemical spot tests and TLC (system A) were carried out following, the methods by Walker & James (1980) and Orange et al. (2001). TAXONOMIC DESCRIPTION Family: Verrucariaceae Genus: Agonimia Agonimia tristicula (Nyl.) Zahlbr., Österr. bot. Z. 59: 351. 1909. –Verrucaria tristicula Nyl., Flora 48: 356. 1865. Plate 1, figures A-D Description: Thallus terricolous, squamulose; squamules minute, crowded, adnate to ascending, flat to convex, roundish to elongate, 0.1–0.5 long and 0.1– 0.3 mm wide; upper surface rough, greyish brown to greenish brown or dark brown to black; lower surface pale, ecorticated; algal cells distributed throughout the thallus, chlorococcoid, cells rounded up to 0.5 μm.
