Abstract

Five surveys were carried out in the Wuliangshan area, Yunnan Province, P.R. China, based on a combination of morphological features and molecular evidence. Around 2454 specimens of wood-decaying fungi were collected. The paper summarizes the obtained results on the wood-decaying fungi of this area, consisting in 95 species distributed in 59 genera, 23 families and 9 orders. Their hosts and substrates were also identified. A checklist of wood-decaying fungi is given. Sequences of the ITS nrRNA gene region of the studied specimens were generated and phylogenetic analysis was performed with maximum likelihood, maximum parsimony and Bayesian inference methods. The present list of wood-decaying fungi enriches the knowledge of fungal diversity worldwide and supplies the basic data for future applications.

Highlights

  • Fungi are a diverse, monophyletic group of eukaryotes which have immense ecological and economic impacts

  • Fresh fruiting bodies of basidiomycetous macrofungi growing on angiosperm stumps, trunks and branches were collected by the systematically surveyed selected cells in the macroarea through the woods for 5 sampling points within 1 × 1 km2 2–3 times every year in the Wuliangshan area of Yunnan Province from October 2017 to January 2019

  • The Bayesian method resulted in a similar topology with an average standard deviation of split frequencies = 0.009891 (BI)

Summary

Introduction

Monophyletic group of eukaryotes which have immense ecological and economic impacts. These organisms play an important role in ecosystems as diverse as soil, leaves, trees, wood, and hidden layers within their substrate [1]. The diversity for flora of seed plants in the Yunnan Province is higher than other areas in China, and the endemic species of woody plants are rich, in which both supply good substrates for wood-decaying fungi. Wooddecaying fungi include most basidiomycetes and ascomycetes that grow on various kinds of wood, such as living trees, dead standing trees, fallen trunks, fallen branches and stumps, which can be used for industrial, medicinal, edible and economic value [5,6,7,8,9,10], and display a considerable ability to transform or degrade different environmental contaminants on their extensive organic compound degradation abilities [1].
