Abstract

Lichen is a symbiosis between fungi and algae that form a unique individual so that in terms of morphology and physiology it is a unity. The diversity of lichen that grows on trees is influenced by environmental conditions, such as the level of air pollution in an area. This study aims to identify morphologically the types of lichens found in the stems of Wodyetia bifurcata and to determine the differences in the types of lichens found at each level of traffic density and the types of lichens that can be used as bioindicators of air pollution. This research was conducted in December 2021-February 2022, Located on Jl. Parameswara Palembang and the Sriwijaya University Indralaya Area. The identification takes place at the Physiology and Developmental Laboratory of the Department of Biology. From the research, it was found that 21 types of lichens live on the trunk of squirrel-tailed palms and obtained 2 types of the thallus, namely crustose and foliose thallus types with sexual reproductive organs in the form of apothecia, perithecia, and pycnidia, and asexually in the form of soredia and Isidia. Traffic density affects the color and diversity of lichen, the higher the level of traffic density, the color of the lichen will fade or dull. In areas of high traffic density, 2 types of lichen were found, 15 species were found in moderate traffic density, and 18 species were found in low traffic density. From the results obtained there are 5 types of lichen that can be used as bioindicators of air pollution, including Buellia stellulata, Glyphis cicatricosa, Glyphis scyphulifera, Pyrenula platysoma, Sarcographa tricosa
