目前还没有报道过与杜氏越桔变种（Vaccinium dunalianum var.）urophyllum是我国重要的药用植物。在这项研究中，几个内生菌株分离自该主机。通过形态学分析和nuc rDNA ITS 1 -5. 8 S-ITS 2（ITS条形码）及其他7个基因区（GAPDH、CAL、ACT、CHS-1、HIS、GS、TUB 2）的DNA序列分析，发现了一个新种--玉龙刺盘孢Colletotrichum yulongense和一个已知种--玉龙刺盘孢C.菱形。两种炭疽菌都有描述。宿主的多样性和广泛的分布，表明其他内生Colletotrichum物种的可能性在V. dunalianum var. urophyllum，这需要进一步研究。对杜氏葡萄炭疽病菌的致病性进行了研究。urophyllum也需要测试。
No species of Colletotrichum have been reported associated with Vaccinium dunalianum var. urophyllum, which is a significant medicinal plant in China. In this study, several endophytic strains were isolated from this host. Morphology and analysis of DNA sequences of nuc rDNA ITS1-5.8S-ITS2 (ITS barcode) and seven other gene regions (GAPDH, CAL, ACT, CHS-1, HIS, GS, TUB2) revealed a new species, Colletotrichum yulongense and a previously described species, C. rhombiforme. Both Colletotrichum species are described. The diversity and broad distribution of the host, suggest the likelihood of other endophytic Colletotrichum species in V. dunalianum var. urophyllum and this requires further investigation. The pathogenicity of the Colletotrichum species isolated from V. dunalianum var. urophyllum also needs testing.
