Basidiospore Wall Ultrastructure and Tissue System Morphology in the Genus Calostoma in North America
Preview not available

Abstract

The three North American species of Calostoma and one variety were studied from both fresh and dried material. Spores were examined using light microscopy as well as scanning and transmission electron microscopy. The structure of the spore wall is described for the first time for the three species. Tissue systems in the sporocarps were studied from immature and mature specimens using light microscopy. New information is presented on the arrangement of the tissue systems and the structure of the walls. Complete descriptions of each species are presented and accompanied by information on their known distribution in eastern North America.
