Abstract
Lichenesis a symbiosis between fungi (mycobionts) from Ascomycetes and Basidiomycetes, and algae (phycobionts) from Cyanobacteria or Chlorophyceae so that morphology and physiology are one unit. Lichenes corticolous live as epiphytes in the substrate of tree bark branches. Lichenes grow in the university area of North Sumatra where many shade trees are found as the substrate. This research used survey method and morphometric method was used to identify the morphology of licheness. Sampling was found in 4 areas of North Sumatran Higher Education: 1. Universitas Negeri Medan, 2. Universitas Sumatera Utara, 3. Universitas Medan Area, 4. Institut Teknologi Sawit Indonesia. This study found 23 species of lichenes from 11 families: Cryptothecia striata, Cryptothecia scripta, Arthonia radiata, Cryptothecia granulatus, Arthonia patellulata (Family Athoniaceae),Xanthoparmelia consponge, Pectenia plumbea,Flavopuctelia soredica (Family Parmeliaceae), Hypogymnia physodes (FamilyHypogymniaceae),Dirinaria applanata (Family Caliciaceae), Lepraria incana, Lepraria lobbyficans (Family Streocaulaceae), Ochreolechia subviridis (Family Pertusariaceae), Lecanora symmicta, Lecanora strobilina, Lecidella elachoroma (Family Lecanoraceae), Ochrolealy tartareaOrchrolechiacea),Viridothelium virens(Family Trypeteliaceae), Rinodina roboris (Family Physciaceae). The types of licheness found included crustose and foliose thallu types.
