WebEpiphytes on leaves of Polytrichum commune Hedw. were observed and studied with SEM and TEM. A unicellular green alga, a fungus, and a rod-shaped bacterium were present on both leaf surfaces. Culturing experiments led to the identification of the alga as Chlorococcum sp. and the fungus as Trichoderma viride Lk. ex Fr. (Deuteromycetes).
