Systematics and species diversity of botryosphaeriaceous fungi

Abstract

Botryosphaeriaceous fungi are an important ascomycete group (Botryosphaeriales, Dothideomycetes, Pezizomycotina, Ascomycota). They play essential roles in economic and ecological environments, especially in agroforestry ecosystems. In this overview, we introduce a wide variety of ecological functions of botryosphaeriaceous fungi. The taxonomic studies of the family Botryosphaeriaceae in its early stages have been reviewed in details since 1823, especially the two major classification systems proposed by von Arx & Müller and Barr. The research status, progress based on holomorphological characteristics and multilocus DNA sequence data are summarized towards updating our understanding of species diversity and classification systems of the group. In addition, the research history, current status and work to be done of the group in China are briefly stated. Problems regarding biodiversity and phylogeny are discussed. Research perspectives are proposed based on taxonomic features, species concepts and exploration of bioresources. This review is expected to provide useful information about effective utilization of fungal resources and control of the harmful effects of botryosphaeriaceous fungi.
