“…So far, the Indian subcontinent has been discovered with only 3,005 lichenized and lichenicolous fungal taxa (Rajaprabu and Ponmurugan 2022a,b). One of the major biodiversity hotspots of the Eastern Ghats (Sirumalai) was determined with only 96 species, the exact opposite direction of the Western Ghats, Megamalai (Tiger reserve and Wildlife sanctuary), was reported with 101 species (Rajaprabu et al 2021;Rajaprabu and Ponmurugan 2022a,b).…”

Abstract. Subbaiyan R, Ganesan A, Dhanuskodi S. 2023. Ecolichenology of Eastern Ghats diversity against climatic fluctuations in Kolli Hills, India. Biodiversitas 24: 625-635. Lichens are major components of earthbound and marine environments. A lichen is a symbiotic form of algae and fungi adapted to survive in different altitudes and environmental conditions. The lichen morphology is divided into three, based on their habitat: crustose, foliose, and fruticose lichens. Eastern Ghats (EG) contribute significantly to both the endemicity and species richness of the Indian region. However, EG forests are relatively unexplored and have received less conservation consideration than the Western Ghats. Unexplored Eastern Ghats were studied to analyze the ecolichenology against climatic fluctuations. The objective of this paper is to build a stock of epiphytic lichens within the Kolli slopes. Kolli Hills are one of the ancient richest floral and faunal biodiversity hotspots of Eastern Ghats. It is assessed from the year 2018 to that 2021 with different climatic seasonal variations. The least diversity was found with the Arthonioid > Usneoid > Scaly > Ramalinoid types. Highly denser than the Parmelioid foliose and Usneoid, the Ramlinoid species was rich in numbers with healthy thallus. The population was stopped, or the least amount of thallus growth was noticed from the high rainfall season and gradual reduction in the summer. The Ramalinoid and Parmelioid lichens were found to be easy identifiers. The richness was reduced dependently and independently with nature. The health of lichens was encountered with only morphological appurtenance. Based on the lichen group, the maximum distribution was observed in Usneoid and Ramalinoid categories. The last distribution was found with Leprose and Scaly lichens. The forest wealth was described with the denser lichen patches and the shrinkages of Parmelioid lichens, especially the Dirinaria and Parmoterma, acting as a wealth analysis tool of the forest ecosystems.

“…The updated checklist of the country's political boundaries with micro-and macro-lichens included 2303 taxa as of 2010 (Singh and Sinha 2010). So far, approximately 3005 lichen species from 84 families and 468 genera have been distributed across eight lichenogeographical regions (Sinha 2021;Rajaprabu et al 2021; Rajaprabu and Ponmurugan 2022). Among 28 states, Tamil Nadu is the second-most lichen species-populated state ever, which is due to a large track of Western and Eastern Ghats and conducive climatic conditions (Dalip Kumar et al 2015).…”

The population diversity of lichen species was studied by the family multiplicity in different sites from various lichen growth forms from the Eastern Ghats, Western Ghats, and the Coastal regions of Sedhu Samuthra, Coramantal and Madras Marina in Tamil Nadu state of the Indian Republic. There are 3,005 lichen taxa and subspecies known from the Indian subcontinent. So far, 938 species have been discovered within the geographical boundaries of Tamil Nadu, making it the state with the second-highest diversity of cryptogamic lichens. This collection was found to contain 150 species from 65 genera, among which 41 species were introduced for the state, regional, and national lichen biota. From the ten substrata, Corticolous was the most adhesive and adorable habitat for lichen(s) growth, with 149 taxa, followed by Lignicolous (143), and the fewest lichen species were grown on Lichenicolous (10) and Foliicolous (09). About the study, we include 3 species that were new records for Indian country, 11 species that are new to the Tamil Nadu State lichen biota, 15 species for the Western Ghats biodiversity hotspot, 12 species for Southern India, and Marine lichens. 16 species were new to the Megamalai Tiger Reserve Forest from Cumbum valley. Among the collected species, the common (vernacular) name of the lichen(s) was included. Due to the richness and abundance of natural diversity, the population ecosystem must be explored using artificial intelligence and technology-based customised studies for the benefit of future generations' learning and research.

“…Australian Lichenologists have reported a maximum number of Haematomma species. In India, 2544 lichen species were stated from eight lichenogeographical locations (Rajaprabu et al, 2021). But, only four taxa of Haematomma were recorded in 1968 by D.D.…”

Recent explorations in Megamalai Tiger reserve and Wildlife sanctuary in Tamil Nadu has resulted in the documentation of new bloodstain lichen, Haematomma collatum Haematommone with UV negative taxonomic species. It has been collected for the first time and hence it forms a new record for India. A detailed description of Haematommaceae, Taxonomical keys and Photographs are provided for rapid identification.
