Cinnamomum japonicum Cinnamomum tenuifolium Clinoconidium Cryptobasidiaceae evergreen tree Exobasidiales Lauraceae plant disease taxonomy

Abstract

A new combination, Clinoconidium onumae, is proposed to accommodate Ustilago onumae (syn. Melanopsichium onumae) from Japan, producing galls on shoot buds of Cinnamomum tenuifolium (Lauraceae). This taxonomic treatment is based on observations of gastroid sporulation in peripheral lacunae of the host galls and basidiospore morphology. This species is morphologically and phylogenetically similar to Cl. cinnamomi producing galls on fruits of Ci. burmannii, reported from Taiwan, but differs by having larger basidiospores and different morphology of the gall structures, and by affecting different plant organs.
