The scanning electron-microscopic studies on the fine structures of spore walls of Leucolejeunea unciloba were done in the present study. Summarizing the results mentioned above are as follows : the following structures of spore walls are similar to those of Frullaniaceae as far as known so far : 1) mature spores are multicellular, 2) foramina are scattered on the surface, 3) columnar protuberances extend from the bottom of the foramina (stellate papilla in the optical microscopic view) ; among the Frullaniaceae species, the fine structures of spore walls of Leucolejeunea unciloba are closely near to those of Frullania mayebarae in the minute globose mamilla densely covering all the spore walls, including the foramina-bottom surface and the columnar protuberances arranged in double concentric circles (in this point, somewhat similar to Frullania tamarisci subsp.moniliata, too) . No study of the fine structures of spore walls of Lejeuneaceae has been obtained as yet, and, therefore, the author can not determine the taxonomic relationships between this species and the other members or groups of Lejeuneaceae from the results of this study. The author, however, would like to discuss this problem (as well as already partly done on Frullaniaceae) after more observations of many species of Lejeuneaceae will be made in the future.
