朝鮮半島産Physarum科変形菌類のSEM的研究

It is very important to analyze the characteristics using a SEM, because each part of a sporangium of Myxomycetes has very fine structures. Four species of Physarum natabile, P. nutans,P. viride and Fuligo cinerea belong to Physaraceae developed in Korean Peninsula were taxonomically studied, especially in regard to the surface ornamentation of a sporangium, aethalium, peridium, capillitium, calcareous granule, spore and other taxonomical factors in detail using a SEM in this study. The author clarified the morphological characteristics and gave a few new taxonomical aspects. Physarum natabile, P. nutans and P. viride have a globosal sporangium each, Fuligo cinerea has an aethalium. P. notabile, P. nutans and P. viride have conspicuous and numerous carcareous granules on an outher surface of a peridium, and they have fine warts and roughened on an inner surface of a peridium. All of four species have a capillitium each and it is consited of nodes and internodal threads. Sometimes nodes and internodal threads have carcaleous granules. These species of P. natabile, P. nutans and P. viride have a globosal spore each. Fuligo cinerea has a two types. One is globosal, another one is ellipsoid. Four species has each peculiar ornamentaion on a surface of a spore. P. natabile has papillae, P. nutans has irregular star shaped protuberances, P. viride has irregular pillar shaped protuberances and Fuligo cinerea has irregular angled warts on a surface of a spore
