炭疽病是由炭疽菌属（Colletotrichum species）引起的30多个植物属的严重病害。在不同的国家已经报道了几种炭疽菌感染辣椒。虽然中国是最大的辣椒生产国，但人们对感染当地辣椒的物种知之甚少。为此，我们从全国29个省、市、自治区采集辣椒样品，分离到1285株辣椒病菌。对所有菌株的形态特征进行了观察和比较，并对选出的代表菌株进行了ITS、ACT、CAL、CHS-1、GAPDH、TUB2和HIS 3等多位点系统发育分析。共鉴定出15种炭疽菌，其中C. fioriniae、C. fructicola、果斑叶蝉C. gloeosporioides，C. scovillei和C. truncatum是普遍的。3个新种，C. conoides、锥花C. grossum，和C. Liaoningense，本文对其进行了鉴定和描述。刺盘孢（Colletotrichum aenigma）、刺盘孢C. climbing，C. endophytica、内生隐杆藻C. hymenocallidis、C. incanum，C. karstii和C. viniferum为首次报道。除C.内生植物本研究加深了对辣椒炭疽病病原种类的认识，为辣椒炭疽病的有效防治提供了有益的信息。
Anthracnose caused by Colletotrichum species is a serious disease of more than 30 plant genera. Several Colletotrichum species have been reported to infect chili in different countries. Although China is the largest chili-producing country, little is known about the species that have been infecting chili locally. Therefore, we collected samples of diseased chili from 29 provinces of China, from which 1285 strains were isolated. The morphological characters of all strains were observed and compared, and multi-locus phylogenetic analyses (ITS, ACT, CAL, CHS-1, GAPDH, TUB2, and HIS3) were performed on selected representative strains. Fifteen Colletotrichum species were identified, with C. fioriniae, C. fructicola, C. gloeosporioides, C. scovillei, and C. truncatum being prevalent. Three new species, C. conoides, C. grossum, and C. liaoningense, were recognised and described in this paper. Colletotrichum aenigma, C. cliviae, C. endophytica, C. hymenocallidis, C. incanum, C. karstii, and C. viniferum were reported for the first time from chili. Pathogenicity of all species isolated from chili was confirmed, except for C. endophytica. The current study improves the understanding of species causing anthracnose on chili and provides useful information for the effective control of the disease in China.
