This study is unique as it compares traditional and high-resolution culture-independent approaches using the same set of samples to study the saprotrophic fungi on Vitis vinifera. We identified the saprotrophic communities of table grape (Red Globe) and wine grape (Carbanate Gernischet) in China using both traditional and culture-independent techniques. The traditional approach used direct observations based on morphology, single spore isolation and phylogenetic analysis yielding 45 taxa which 19 were commonly detected in both cultivars. The same set of samples were then used for Illumina sequencing which analyzed ITS1 sequence data and detected 226 fungal OTUs, of which 176 and 189 belong to the cultivars Carbanate Gernischet and Red Globe, respectively. There were 139 OTUs shared between the two V. vinifera cultivars and 37 and 50 OTUs were specific to Carbanate Gernischet and Red Globe cultivars respectively. In the Carbanate Gernischet cultivar, Ascomycota accounted for 77% of the OTUs and in Red Globe, almost all sequenced were Ascomycota. The fungal taxa overlap at the genus and species level between the traditional and culture-independent approach was relatively low. In the traditional approach we were able to identify the taxa to species level, while in the culture-independent method we were frequently able to identify the taxa to family or genus level. This is remarkable as we used the same set of samples collected in China for both approaches. We recommend the use of traditional techniques to accurately identify taxa. Culture-independent method can be used to get a better understanding about the organisms that are present in a host in its natural environment. We identified primary and secondary plant pathogens and endophytes in the saprotrophic fungal communities, which support previous observations, that dead plant material in grape vineyards can be the primary sources of disease. Finally, based on present and previous findings, we provide a worldwide checklist of 905 fungal taxa on Vitis species, which includes their mode of life and distribution.

“…Anthracnose is a serious disease of grapes caused by Colletotrichum Corda species and has been reported by Yan et al (2013Yan et al ( , 2015. Other grape diseases have also been surveyed and published, and these data may help in disease control (Dissanayake et al 2015;Jayawardena et al 2015). Dai et al (2007) recorded 102 potential forest pathogens as a result of field surveys throughout China, which are important for protection of forest resources.…”

A survey and analysis of fungal taxa introduced over seven decades is presented. The numbers of introduced taxa were collated from ten editions of the Dictionary of the Fungi as well as from the Index of Fungi. In total, around 9100 genera and 108,000 species had been introduced by 2014. Between 1943 and 2008, the average numbers of introduced novel genera increased annually by 73 and species by 950. However, between 2008 and 2012, the average numbers of introduced novel genera increased annually by 110 and species by 1430. There were 1203 novel genera and 16,912 novel species described between 2001 and 2012, with an average of 100 new genera and 1397 new species published annually during the period. Advances in molecular techniques have accelerated the discovery of novel taxa; it therefore seems likely that many more novel taxa will be described in the future. Between 2001 and 2012, 1529 novel species were described from China, accounting for 9.2 % of all novel species descriptions worldwide. Around 17,000 fungal species had been recorded in China by 2014 with 5700 basidiomycete species, and 6700 species from important fungal groups being documented in Flora Fungorum Sinicorum with detailed descriptions, microscopic drawings and lists of voucher collections. An overview of studies on fungal diversity in China is presented.

Pseudocercospora is an important plant pathogenic genus causing leaf spots on grapevine leaves and other hosts worldwide. A survey of vineyards in four provinces of China was carried out to identify the causal agent of Pseudocercospora leaf spot. A phylogenetic analysis based on a combination of LSU, ITS and ACT loci, coupled with morphology, showed that Pseudocercospora vitis is the sole causal agent of this leaf spot disease. This study represents the first attempt to identify and characterize the cercosporoid species causing Pseudocercospora leaf spot in China using morphological and molecular approaches.
