Abstract

Abstract:

In order to study the taxonomic status of Tremella sanguinea Y.B. Peng and its fungal host, pure cultures, named as XE01 and XE02, were respectively obtained from basidiospores and basidiocarp tissues of Tremella sanguinea cultivated on Tilia sp. logs. The colony and microscopic morphology, as well as the molecular phylogeny based on rDNA-ITS of the two strains were then analyzed. It was found that the colonies of XE01 on PDA medium were white-creamy, smooth and moist; the cells were oval, budding and yeast-like. In the phylogenetic tree based on rDNA-ITS, XE01 was nested within in the clade of the genus Phaeotremella, and showed closer phylogenetic relationship to P. neofoliacea and P. eugeniae according to the genetic distances. The colonies of XE02 on PDA medium were fluffy and white; the hyphae were septate, and rarely branched; spherical spores and clamp connections were present; the inoculated agar medium was reddish brown due to the production of diffusible pigments. In the phylogenetic tree based on rDNA-ITS, XE02 was nested within the clade of the genus Stereum and showed closer phylogenetic relationship to S. rugosum according to the genetic distances. Based on these results, XE01 might be the free-living unicellular yeast state of T. sanguinea, and XE02 might be its fungal host. The results would contribute towards the classification of T. sanguinea and its fungal host, as well as the identification of their germplasm resources.

Key words: Tremella sanguinea, fungal host, morphology, molecular phylogeny
