Title: The Mode of Cytoplasmic Separation between a Basidiospore and a Sterigma in Shiitake Mushroom, Lentinus edodes
Author: Y. Nakai

Abstract:

Shiitake mushroom, Lentinus edodes (Berk.) Sing., is a wood-inhabiting Hymenomycete and the most important edible mushroom which is commonly cultured on bed-logs of Fagaceae in Japan. As regard cytology of shiitake fungus, the author demonstrated previously the internal and external fine structure of basidiosporogenesis, basidiospore discharge and nuclear movement into basidiospores following hymenial development (Nakai and Ushiyama 1974a,b; Nakai, 1975; Nakai and Ushiyama, 1978). Prior to discharge of a mature basidiospore from the apex of a sterigma, the cytoplasm of a basidiospore is necessary to be separated from that of a basidium. The mode of the cytoplasmic separation process, however, has not been clarified exactly. Recently, the author found the close association of complex membranous configuration regarding separation of basidiospore cytoplasm from a basidial cell in this fungus. The present paper describes this configuration with special reference to its origin and the possible function which is related to cytoplasmic separation between the basidiospore and the basidial cell.
