The present communication includes a list of 411 species of lichens under 147 genera reported or described from India after the publication of “Indian Lichens: An Annotated Checklist” by Singh and Sinha (2010). According to latest issue of Plant Discoveries 2016 (Singh and Dash, 2017) 2511 species of lichens are known from India. However, a thorough collation including less popular and online journals where taxonomic novelties in the form of new records are not mentioned, revealed significant increase during the past seven years. By addition of 411 species to the list of Singh and Sinha (2010), now the total number of lichens for India raises up to 2714 species. However, due to nomenclature changes and synonymy, revisions, etc. this data may change. Few species which were not included in Singh and Sinha (2010) are also included in this list. Species simply transferred to other genera without affecting the number tally are not listed here. Like-wise obligate lichenicolous and non-lichenized fungi are not included in the present list. The current list indicates that large number of taxa are reported from the family Graphidaceae (106 spp.) where genus Graphis alone counts 34 species. Large number of taxa are also reported from order Arthoniales (52 species) with Opegrapha representing 17 species. The species listed here follows the pattern of; species name (in bold), reference, and name of the state from where the species is reported. For the references cited in this paper readers may refer ‘Bibliography to the Indian lichens from the year 2010 onwards’ by Joseph et. al. (2018) published in the same issue of this journal.

The present paper deals with 25 new records of lichens under 19 genera and 11 families for the state of Assam in India.  The newly reported species from Assam are Alyxoria apomelaena, A. culmigena, A. varia, Caloplaca pseudisteroides, Cryptothecia striata, Diorygma rupicola, Dirinaria papillulifera, Flavoplaca citrina, Graphis sundarbanensis, Herpothallon echinatum, Lecanographa rufa, Letrouitia muralis, Myriotrema clandestinum, Opegrapha discolor, Parmotrema crinitoides, Phaeophyscia hispidula, Porina eminentior, P. interstes, P. mastoidella, Pyrenula submastophora, P. thelomorpha, Rinodina oxydata, Synarthonia bicolor, Zwackhia bonplandii, and Z. viridis.  Brief descriptions of these additional lichen taxa from Assam are provided to facilitate their identification.

Six species of the genus Malmidea, M. atlantica (M. Cáceres & Lücking) M. Cáceres & Kalb, M. duplomarginata (Papong & Kalb) Kalb & Papong, M. hypomelaena (Nyl.) Kalb & Lücking, M. papillosa Weerak. & Aptroot, M. subaurigera (Vain.) Kalb et al., and M. variabilis Kalb, are reported as new records to India. A key to all known Indian species of Malmidea is provided.
