Abstract
The environmentally related patterns of occurrence of 14 species of collemiform lichens ( Collema s. l. sensu Degel.: C. ( Rostania ) callibotrys var. callibotrys Tuck., C. complanatum Hue, С. ( Enchylium ) conglomeratum var. conglomeratum Hoffm., C. ( Arctomia ) fasciculare var. fasciculare (L.) Weber ex F. H. Wigg., C. japonicum (Müll. Arg.) Hue, C. leptaleum var. leptaleum Tuck., С. ( Enchylium ) ligerinum (Hy) Harm., C. nepalense Degel., C. pulcellum var. pulcelllum Ach., С. ( Enchylium ) pycnocarpum Nyl. (= C. conglomeratum var . crassiusculum (Malme) Degel.), C. shiroumanum var. shiroumanum Räsänen, C. subconveniens Nyl., C. subflaccidum Degel., C. substipitatum var. substipitatum Zahlbr.) on trunks of various tree species in different types of forests, as well as their distribution in the south of the Russian Far East, have been analyzed. It was established that the greatest diversity of the species of collemiform lichens (10 and 9) was registered on the oak ( Quercus mongolica Fisch. ex Ledeb.) and the linden ( Tilia mandshurica Rupr. et Maxim., T. amerensis Rupr.), while the lowest diversity was found on deciduous trees with smooth thin bark. The oak-broad-leaved and coniferous-broad-leaved (with Pinus koraiensis Siebold et Zucc.) forests are best suited to the ecological needs of the collemiform lichens; in these forests, 8 and 11 species, respectively, have been registered. The three most thermophilic oceanic species, C. complanatum , C. japonicum , and C. subconveniens , have been found only on the coast of the Sea of Japan in the narrow zone of direct influence of the monsoon climate.
