The epiphytic algae on Prusiala Icubeica include the three genera(apecies) of Cyanophyta, which are Aphanocapsa tivularis ,Oncobyrsa nvularis and Xenococcus fceram,and five genera (species,variety)of Bacil-lariophyta, which are Achnanthes,Cocconeis placentida var. euglypta,Cynbella, Camptumeirta and Synedra. It is the first report that Ayluiruxapsa rieidaris and Coccuneis plucentula var. euglyptu, are epiphyte on Prasiola.
