Cultured tissues of mycobionts are obtained from the following 12 species of Umbilicaria lichens : Umbilicaria aprina, U. caroliniana, U. cylindrica, U decussata, U. esculenta, U. hyperborea, U. kisovana, U. muehlenbergii, U. pensylvanica, U. polyrrhiza, U. proboscidea, and U. vellea. These lichens (intact) are expected for medical usages (I.e.control against cancer and AIDS). Phycobionts ( Trebouxia) are also isolated from the following five Umbilicaria species : U. caroliniana, U. esculenta, U. hyperborea, U. muehlenbergii, and U. pensylvanica. Mycobionts grow separatedly from phycobionts in all 12 Umbilicaria species under at 15℃, and dark condition in MY-medium. My-cobionts of Umbilicaria caroliniana, U. muehlenbergii, and U. pensylvanica grow well under at 15℃ and dark conditions in MY-medium. On the contraly, mycobionts of the following three species scarcely grow : U. aprina, U. esculenta, , and U. proboscidea. Mycobionts of U. muehlenbergii and U. pensylvanica grow about 100 times their intial weight at 15℃ after 16 weeks culture.
