Abstract
Hemileia gardeniae-floridae is an accepted name for a Cape jasmine (Gardenia jasminoides) rust fungus distributed in East Asia. The fungus name was based on uredinial anamorph collected in Taiwan in 1931. The fungus was rarely collected in Taiwan and southern Japan, and its telial stage remained unknown. Microscopic examination of the type materials of H. gardeniae-floridae and Uredo gardeniae-floridae, which was once proposed to replace H. gardeniae-floridae, resulted in discovery of teliospores on the type of U. gardeniae-floridae. The teliospores are mostly napiform and produced on a sporogenous cell emerging through host stoma. A hemileioid rust fungus, producing both urediniospores and teliospores on Golden gardenia (G. sootepensis), was found in Thailand and morphologically identified to H. gardeniae-floridae. Another Hemileia species on Forest jasmine (G. thunbergia), H. gardeniae-thunbergiae, first found in Angola, Africa, is distinct from H. gardeniae-floridae in producing smaller urediniospores than those of H. gardeniae-floridae.
期刊介绍:
Mycoscience is the official English-language journal of the Mycological Society of Japan and is issued bimonthly. Mycoscience publishes original research articles and reviews on various topics related to fungi including yeasts and other organisms that have traditionally been studied by mycologists. The research areas covered by Mycoscience extend from such purely scientific fields as systematics, evolution, phylogeny, morphology, ecology, physiology, biochemistry, genetics, and molecular biology, to agricultural, medical, and industrial applications. New and improved applications of well-established mycological techniques and methods are also covered.
