The Botryosphaeriaceae is a species-rich family that includes pathogens of a wide variety of plants, including species of Eucalyptus. Recently, during disease surveys in China, diseased samples associated with species of Botryosphaeriaceae were collected from plantation Eucalyptus and other plants, including Cunninghamina lanceolata, Dimocarpus longan, Melastoma sanguineum and Phoenix hanceana, which were growing adjacent to Eucalyptus. In addition, few samples from Araucaria cunninghamii and Cedrus deodara in two gardens were also included in this study. Disease symptoms observed mainly included stem canker, shoot and twig blight. In this study, 105 isolates of Botryosphaeriaceae were collected from six provinces, of which 81 isolates were from Eucalyptus trees. These isolates were identified based on comparisons of the DNA sequences of the internal transcribed spacer regions and intervening 5.8S nrRNA gene (ITS), and partial translation elongation factor 1-alpha (tef1), β-tubulin (tub), DNA-directed RNA polymerase II subunit (rpb2) and calmodulin (cmdA) genes, the nuclear ribosomal large subunit (LSU) and the nuclear ribosomal small subunit (SSU), and combined with their morphological characteristics. Results showed that these isolates represent 12 species of Botryosphaeriaceae, including Botryosphaeria fusispora, Cophinforma atrovirens, Lasiodiplodia brasiliense, L. pseudotheobromae, L. theobromae and Neofusicoccum parvum, and six previously undescribed species of Botryosphaeria and Neofusicoccum, namely B. pseudoramosa sp. nov., B. qingyuanensis sp. nov., B. wangensis sp. nov., N. hongkongense sp. nov., N. microconidium sp. nov. and N. sinoeucalypti sp. nov. Aside from B. wangensis, C. atrovirens and N. hongkongense, the other nine Botryosphaeriaceae species were isolated from Eucalyptus trees in South China. Botryosphaeria fusispora (26 % of the isolates from Eucalyptus) is the dominant species, followed by L. pseudotheobromae (23 % of the isolates from Eucalyptus). In addition to species found on Eucalyptus trees, we also found B. pseudoramosa on M. sanguineum; B. wangensis on C. deodara; C. atrovirens on D. longan; L. theobromae on C. lanceolata, D. longan and P. hanceana; and N. hongkongense on A. cunninghamii. Pathogenicity tests showed that the 12 species of Botryosphaeriaceae are pathogenic to three Eucalyptus clones and that Lasiodiplodia species are the most aggressive. The results of our study suggest that many more species of the Botryosphaeriaceae remain to be discovered in China. This study also provides confirmation for the wide host range of Botryosphaeriaceae species on different plants.

“…As is true for most groups in the Botryosphaeriaceae , Botryosphaeria has been substantially revised in recent years using a combination of DNA sequence and morphological data. The genus now accommodates 16 species for which clear taxonomic descriptions and DNA sequence data are available (Phillips et al 2013 ; Slippers et al 2014 ; Xu et al 2015 ; Ariyawansa et al 2016 ; Zhou et al 2016 , 2017 ; Li et al 2018 ).…”

The Botryosphaeriaceae accommodates many important pathogens of woody plants, including Eucalyptus. Recently, Botryosphaeriaceae were isolated from diseased plant parts from surveys of Eucalyptus plantations in the YunNan Province, China. The aims of this study were to identify these Botryosphaeriaceae isolates and to evaluate their pathogenicity to Eucalyptus. A total of 166 isolates of Botryosphaeriaceae were obtained from six regions in the YunNan Province, of which 76 were from Eucalyptus urophylla × E. grandis hybrids, 49 from E. globulus trees, and 41 isolates were from other unknown Eucalyptus species or hybrids. Isolates were identified by comparing DNA sequences of the internal transcribed spacer ribosomal RNA locus (ITS), partial translation elongation factor 1-alpha (tef1), β-tubulin 2 (tub2) and DNA-directed RNA polymerase II subunit (rpb2) genes, and combined with their morphological characteristics. Eleven species were identified, including Botryosphaeria fusispora, B. wangensis, Lasiodiplodia pseudotheobromae, Neofusicoccum kwambonambiense, N. parvum, and six novel species described as B. puerensis, N. dianense, N. magniconidium, N. ningerense, N. parviconidium and N. yunnanense. The dominant species across the regions were N. yunnanense, N. parvum and B. wangensis, representing 31.3, 25.3 and 19.9% of the total isolates, respectively. Species diversity and composition changed across the different climatic zones, despite their relatively close geographic proximity and the fact that some of the species have a global distribution. All the Botryosphaeriaceae species were pathogenic to one-year-old plants of an E. urophylla × E. grandis clone and E. globulus seed-derived plants, but showed significant inter- and intra-species variation in aggressiveness amongst isolates. The study provides a foundation for monitoring and management of Botryosphaeriaceae through selection and breeding of Eucalyptus in the YunNan Province of southwestern China.

“…The genus is characterized by clavate asci with hyaline (sometimes becoming pale brown with age), aseptate (sometimes becoming 1-2 septate with age), fusoid to ellipsoid or ovoid ascospores; with hyaline (sometimes becoming olivaceous or darker with age), thin-walled, smooth, aseptate (occasionally forming 1-2 septate with age or before germination), elliptical to fusiform or clavate conidia (Phillips et al 2013). Several recent studies increased the species to 11 in Botryosphaeria (Slippers et al 2014, Ariyawansa et al 2016, Zhou et al 2016. Of which Botryosphaeria dothidea was regarded as one of the most frequent species as well as latent pathogen associated with canker disease of woody plants (Marsberg et al 2017).…”

Botryosphaeriales is an order comprising of latent fungal pathogens with a wide range of woody hosts. These pathogens represent interesting and diverse fungi with a confusing taxonomy due to their similar morphological characters. Many genera or families of this order have not been robustly sampled or systematically studied in separate hosts and regions, although recent studies have made enormous progress. In this study, five species of Aplosporellaceae and Botryosphaeriaceae were isolated from Juglans regia (Juglandaceae), Rhus typhina (Anacardiaceae) and Ziziphus jujuba (Rhamnaceae) in Dongling Mountain of China. These species include Aplosporella ginkgonis, Aplosporella javeedii, Botryosphaeria dothidea, Phaeobotryon rhoinum sp. nov. and Phaeobotryon rhois. Of which, Aplosporella javeedii and A. ginkgonis were identified as the first records from Ziziphus jujube and Rhus typhina, respectively. Phaeobotryon rhoinum is characterised by its globose, scattered to gregarious pycnidia with ellipsoid to oblong, brown, 1-septate conidia. It can be distinguished from the similar species P. cercidis, P. cupressi, P. mamane, P. quercicola and P. rhois based on host association and conidial size and colour. The results represent the first attempts to study Aplosporella, Botryosphaeria and Phaeobotryon with descriptions and multi-locus phylogenies (ITS, LSU and TEF-1α) in Dongling Mountain of China.
