“…Their details are included in Table 3 for reference, and can be recognised with “none” in the type status column. It may be that some or all of these strains will be designated as epitypes in the future, but for the present it should not be assumed that they represent the species as originally circumscribed.[2]KS20BIG was one of four epitypes designated by Crouch et al (2006) for C. cereale ; the application of the name needs to be more precisely established.[3]Preliminary multilocus analysis suggests that C. chrysanthemi may not be a synonym of C. carthami as stated by Uematsu et al (2012). …”

A review is provided of the current state of understanding of Colletotrichum systematics, focusing on species-level data and the major clades. The taxonomic placement of the genus is discussed, and the evolution of our approach to species concepts and anamorph-teleomorph relationships is described. The application of multilocus technologies to phylogenetic analysis of Colletotrichum is reviewed, and selection of potential genes/loci for barcoding purposes is discussed. Host specificity and its relation to speciation and taxonomy is briefly addressed. A short review is presented of the current status of classification of the species clusters that are currently without comprehensive multilocus analyses, emphasising the orbiculare and destructivum aggregates. The future for Colletotrichum biology will be reliant on consensus classification and robust identification tools. In support of these goals, a Subcommission on Colletotrichum has been formed under the auspices of the International Commission on Taxonomy of Fungi, which will administer a carefully curated barcode database for sequence-based identification of species within the BioloMICS web environment.

“…A preliminary multilocus analysis (Cannon et al ., ) suggested that C. chrysanthemi might not be a synonym of C. carthami , as stated by Uematsu et al . (). Recently, 21 strains that were once identified as C. carthami on the basis of TUB2 were analysed (Uematsu et al ., ; Sato & Moriwaki, ).…”

“…(). Recently, 21 strains that were once identified as C. carthami on the basis of TUB2 were analysed (Uematsu et al ., ; Sato & Moriwaki, ). The strains were divided into three clades: 14 of the strains that clustered with the reference strains of C. chrysanthemi (that were accepted by Damm et al ., ), four strains that were isolated from pot marigold, and three strains from strawberry.…”

“…Colletotrichum acutatum is one of the most pathogenic species within the Colletotrichum genus, causing anthracnose and blight in many agriculturally important hosts, including safflower and other asteraceous species, such as chrysanthemum (Chrysanthemum sp.) and marigold (Calendula officinalis) (V ıchov a et al, 2011;Uematsu et al, 2012). Gloeosporium carthami was first described as the causal agent of safflower leaf blight in Japan (Tanaka, 1917).…”

“…Kwon et al (1998) identified a pathogen that caused anthracnose in safflower, in addition to pot marigold and garland chrysanthemum; the pathogen was assigned to C. acutatum. In 2012, G. carthami from safflower, Colletotrichum chrysanthemi from chrysanthemum and C. acutatum from marigold isolates were morphologically and molecularly examined and assigned to the Colletotrichum carthami species (Uematsu et al, 2012).…”

Characterization and epidemiology of Colletotrichum acutatum sensu lato (C. chrysanthemi) causing Carthamus tinctorius anthracnose

In 2012, Colletotrichum isolates were collected from field‐grown safflower (Carthamus tinctorius) crops in central Italy from plants exhibiting typical anthracnose symptoms. Colletotrichum isolates were also collected from seed surfaces and from within seeds. The genetic variability of these isolates was assessed by a multilocus sequencing approach and compared with those from Colletotrichum chrysanthemi and Colletotrichum carthami isolates from different geographic areas and other Colletotrichum acutatum sensu lato‐related isolates. Phylogenetic analysis revealed that all of the strains isolated from C. tinctorius belonged to the species described as C. chrysanthemi, whereas all of the strains belonging to C. carthami had been isolated from Calendula officinalis. Phenotypic characterization of isolates was performed by assessing growth rates at different temperatures, morphology of colonies on potato dextrose agar (PDA) and the size of conidia. All C. chrysanthemi isolates from safflower had similar growth rates at different temperatures, comparable colony morphologies when grown on PDA and conidial sizes consistent with previously described C. chrysanthemi isolates. Pathogenicity tests were performed by artificially inoculating both seeds and plants and confirmed the seedborne nature of this pathogen. When inoculated on plants, C. chrysanthemi caused the typical symptoms of anthracnose on leaves. This is the first record of this pathogen on C. tinctorius in Italy, and it presents an updated characterization of Colletotrichum isolates pathogenic to safflowers in Europe.
