Norman, belonging to family Ophioparmaceae, a rare lichen species has been recorded for the first time from north east alpine Himalaya, India after the gap of more than hundred years, when it was first recorded by Leighton from Sikkim in the year 1879. This saxicolous species is found growing together with other saxicolous lichens and mosses. This species was recorded previously from alpine regions of Eastern Nepal.

Though high altitude alpine habitats, due to their physico-chemical constrains are some of the extremely fragile habitats, they harbor unique diversity of life forms. Indian Himalayan habitats are abode of a diverse lichen community, and have evolved into various growth forms. Lichens inhabit nearly all the terrestrial and boreal domains of the region. Lichens are more sensitive to changes in environmental conditions than all other plant forms. Passive temperature enhancing systems (PTES) such as open top chambers (OTC) are most appropriate devices to experimentally simulating the global temperature alleviation as they use trapped solar energy to enhance the ambient temperature of experimental area. PTES experimental setups utilizing lichens can be a very efficient method for studying effect of temperature alleviation on plants.
