Taxonomic Study of Lichens of Phulchowki Hills, Lalitpur District (Kathmandu Valley)
Scientific World, 2010
The lichens were collected from different altitudinal gradient ranges from 1500-2700 m. above sea level of Phulchowki hill. They were identified on the basis of their morphological, anatomical and chemical studies (colour reaction, thin layer chromatography and microcrystallography). A total of thirty-two species of lichens were identified which comprises nine families and ten genera. Among them family Parmeliaceae was largest one which comprises ten species. Key words: Lichens; Crustose; Foliose; Fructicose. DOI: 10.3126/sw.v6i6.2633 Scientific World, Vol. 6, No. 6, July 2008 44-51
An extensive research on deciphering lichen diversity in the high Nepalese Himalaya was undertaken in two subsequent years in Manaslu Conservation Area (MCA) and Sagarmatha National Park (SNP). Altogether, 621 specimens were collected from these two regions, viz., 173 from MCA and 448 from SNP, which resulted in the occurrence of a total of 13 species of lichens from MCA (belonging to 4 families) and 69 species belonging to 15 different families from SNP. Among the lichen families reported from these two study sites, family Parmeliaceae (7 and 29 species from MCA and SNP, respectively) was the dominant one followed by Physciaceae (12 species from SNP) and Cladoniaceae (4 and 8 from MCA and SNP, respectively). Thus, this research work, to some extent, reveals the lichens enrichment in the study region, furnishing much new insights that can be used as a composite signal of environmental quality and future bio-monitoring studies.
An enumeration of lichens from the Bageshwar district of Kumaun Himalaya, Uttarakhand, India
The paper, lists 361 species of lichens belonging to 89 genera and 35 families from the Bageshwar district of Uttarakhand. The study is based on the published literature and specimens in the herbarium of National Botanical Research Institute, Lucknow (LWG). Dhakuri and Khati areas, situated between 2683 2210 m have the highest diversity of lichens represented by 215 and 172 species, respectively. Lichen, families Parmeliaceae with 23 genera and Physciaceae with 8 genera are the dominant families in the district. Among the different lichen genera, Cladonia with 22 species and Heterodermia with 18 species exhibit their dominance in the area. Trees bear a luxuriant growth of lichens and particularly Quercus, Pinus, Alnus and Cedrus exhibit the maximum diversity of epiphytic lichens in the district.
New addition to the Lichen flora of Uttarakhand, India
2016
The present paper revealed the occurrence of nine lichen species from Uttarakhand for the first time. The species belong to six families (Cladoniaceae, Lecanoraceae, Parmeliaceae, Peltigeraceae, Physciaceae, Verrucariaceae) and represents four growth forms of lichens found growing on soil, rock and soil over rock. Brief moropho-taxonomic details of all the nine species have been provided with their ecology and distribution.
Lichen diversity of Padder Valley Kishtwar (J), India
Journal of Applied and Natural Science
Lichens are one of the most successful group of organisms and form an important aspect of biodiversity of any region. But still lichens are under explored in most of regions. The present work has been carried out in Padder Valley, Kishtwar, Jammu and Kashmir (J&K). A thorough survey of the lichen diversity from all the possible habitats was conducted in the study area which indicated the presence of 110 species belonging to 54 genera and 23 families. Parmiliaceae has been recorded as the largest family (16 genera, 27 species) and is followed by Physciaceae (8 genera, 14 species). Four families have been observed to be monotypic. Lecanora has been recorded as dominant genera with 7 species followed by Peltigera with 5 species. Corticolous was most preferred substratum exhibited by 61 species while foliose was the most dominant type of growth form represented by 52 species. The study has added 94 lichen taxa as new records for district Kishtwar and is first of its kind in Padder Vall...
Lichen Diversity of Kargil Town and Its Adjoining Areas, J & K
International Journal of Current Research and Review, 2013
The present study involves an investigation into the biodiversity of Lichens in the Kargil district of Ladakh Division of Jammu and Kashmir State situated in the North of India. The study was promulgated to get some idea about the diversity and distribution pattern of lichens as this area is poorly explored yet. A total of 25 lichen species were collected from six (6) different sites belonging to 13 genera and 8 families. The crustose lichens showed marked dominance represented by 17 species followed by foliose represented by 8 species. Sanko and Kako-shilikchey record maximum number of 16 and 12 lichen species respectively. The whole data lead to formulate a naturality judgement that though the present record of lichen species may appear to be less but keeping in view the extreme climatic conditions and poor, degraded vegetative cover of landscape, this number may be considered good and the area may be regarded as lichen rich area.
Species Diversity of Lichens in Bhoranj Block of Hamirpur District, Himachal Pradesh
Journal of Biological and Chemical Chronicles
During the present study sixty six specimens of lichens were collected from Bhoranj block of Hamirpur district, Himachal Pradesh. A total of twelve species of lichens belonging six genera and four families were recorded. All the species were identified on the basis of morphological and anatomical investigation. The ecological species diversity (α, β and γ diversity) of twelve species was calculated. Physcia dubia is most common species. All the taxa were deposited in CPUH (The Herbarium,
Distribution pattern of corticolous lichens in different areas of Kathmandu valley, Nepal
Banko Janakari
This study attempts to document the lichen species and their distribution in different areas of Kathmandu valley, Nepal. Twenty sampling sites with different degrees of air pollution categorized as disturbed (industrial, heavy traffic and residential areas) and undisturbed areas (clean area) were selected for the study. Sampling was done using the quadrat method. To enumerate the total number of lichen species found in Kathmandu valley, lichen specimens were collected from inside as well as outside the quadrats. A total of 97 species of corticolous lichens belonging to 21 families and 44 genera were recorded from the study sites. Parmeliaceae was the largest family followed by Graphidaceae. The importance value analysis showed that Candelaria concolor (115.2), Dirinaria aegialita, Lepraria sp., Phaeophyscia hispidula var. hispidula and Physcia sorediosa (106.02) are the most common and dominant lichen species in Kathmandu valley. Among the most common and dominant lichen species, Ca...
The present work describes lichen diversity in Kodagu district, which is also known as micro hotspot situated in the Western Ghats of Karnataka, India. A total of 87 species belonging to 29 families under 50 genera was enumerated during the study. About 25 species of lichens are found to be new record to the lichen flora of Karnataka. Family Parmeliaceae and Physciaceae were dominated with 20 species under 5 genera and 15 species under 7 genera, respectively. Compared to other substratum most of the lichens recorded were corticolous (colonizing bark) with 78 species. Crustose and foliose growth form dominates with about 44% in all the regions. The highest diversity of lichens was enumerated in Nisargadhama [MDF] with 57 species, with highest Shannon-Simpson index of 3.75 and 0.02 respectively in which macrolichens were more dominated. Distribution of lichens in deciduous forest was more when compared to semi-evergreen and evergreen forests. The lichen rich diversity in a small, densely forested area indicates that much exploration regarding the enumeration of lichens is required.

Environment Conservation Journal, 2014
A preliminary survey of lichen diversity in the sub-alpine and alpine ecosystem of Kailash and its environs in upper Bhaderwah region of J&K state has revealed the occurrence of 17 species belonging to 11 families and 15 genera. Parmaliaceae has been recorded as the largest family with 4 species and 4 genera and is followed by Verrucariaceae and Cladoniaceae, each with 2 species and 1 genus. Foliose lichens are dominating the area and are represented by 8 species while crustose are represented by 4 species only. Both, corticolous and saxicolous lichen are represented by 8 species each while 1 species belonged to terricolous group of lichen.
