Abstract
Cyphellaceae, a small and under-studied family of Agaricales, includes mostly saprophytic taxa with varied basidiomes. In this study, we focus on wood-decay species with corticioid or stereoid basidiomes. Phylogenetic analyses of concatenated ITS-nrLSU sequences uncovered seven generic lineages of corticioid or stereoid fungi-Acanthocorticium, Cericium, Chondrostereum, Cunninghammyces, Gloeostereum, Granulobasidium, and Stratocorticium gen. nov. The genus Cericium is shown to be in the Cyphellaceae family, and two new species, Cericium gloeocystidiatum and Stratocorticium sinensis, are described from East Asia. Morphologically, Ce. gloeocystidiatum is characterized by resupinate basidiomes with smooth hymenophores, a dimitic hyphal system with clamped generative hyphae and micro-binding hyphae, cystidia with resinous-like or golden yellow contents, and ellipsoid basidiospores. Stratocorticium is monotypic, differing from Cericium by a trimitic hyphal system of clamped generative, micro-binding, and brown, thick-walled skeletal-like hyphae, clavate to cylindrical cystidia with homogenous, colorless contents, and hyphidia. Descriptions and illustrations are provided for the new taxa and Cericium luteoincrustatum, and a key to corticioid or stereoid genera in Cyphellaceae is included.
期刊介绍:
Journal of Fungi (ISSN 2309-608X) is an international, peer-reviewed scientific open access journal that provides an advanced forum for studies related to pathogenic fungi, fungal biology, and all other aspects of fungal research. The journal publishes reviews, regular research papers, and communications in quarterly issues. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on paper length. Full experimental details must be provided so that the results can be reproduced.
