抄録・要旨

The number of sterigma per basidium of Exobasidium spp was investigated by a scanning electron-microscope and the results were shown in Figs. 1-28.
Ex. vexanss: Two sterigmata and spores per basidium, but not observed three or four sterigmata(Figs. 1-5).
Ex. nudum: The number of sterigma per basidium was typically four, but two, three and five-sterigmata were observed in basidium(Figs. 6-11).
Ex. japonicum: The number of sterigma per basidium was four to seven in this fungus. The case of five or six was common, four or seven sterigmata were rarely(Figs. 12-19).
Ex. gracile：Three or four sterigmata were investigated in basidium, mainly three sterigmata(Figs. 20-22).
Ex. camelliae: Four sterigmata per basidium were typical, and rarely two, three and five sterigmata were observed in this fungus(Figs. 23-28).
