“…Strains of the six species included in the dematium clade appear to be characteristic of temperate environments, though the sample size for several of the species is inadequate to allow definite conclusions as to their climatic range. In general, members of the dematium clade are not significant in economic terms, but C. spinaciae (a pathogen of Beta and Spinacia ; Gourley 1966 , Washington et al 2006 ) and C. circinans (attacking Allium species; Hall et al 2007 , Kim et al 2008 ) both cause substantial crop losses under some circumstances. These two plant pathogenic species occupy a well-defined subclade distinct from a separate subclade made up of the putatively saprobic species C. dematium, C. lineola, C. fructi and C. anthrisci ( Damm et al 2009 ; Fig.…”

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.

Species of Colletotrichum are considered important plant pathogens, saprobes, and endophytes on a wide range of host plants. In Italy, several Colletotrichum species have been reported in glasshouse environments. In this study, we have explored the occurrence, diversity, and pathogenicity of Colletotrichum spp. associated with aromatic and ornamental plants belonging to the Lamiaceae family. Surveys were carried out during the 2011–2018 period in Liguria and Piedmont, Italy. A total of 19 Colletotrichum isolates were collected from symptomatic leaves and seeds of Ocimum basilicum (basil), Origanum vulgare (oregano) and different Salvia spp. A multi-locus phylogeny was established based on the basis of four genomic loci (ITS, GAPDH, ACT and TUB2). The aggressiveness of selected, representative isolates were tested. Colletotrichum isolates were identified as being members of three major species complexes: C. acutatum, C. destructivum, and C. gloeosporioides. Colletotrichum fioriniae, C. bryonicola, and C. fructicola were found in association with leaf lesions on Salvia leucantha, S. nemorosa, and S. greggii, respectively. Colletotrichum nigrum was isolated from twig lesions of S. greggii. Moreover, C. fioriniae and C. ocimi were found to be responsible for causing leaf anthracnose of oregano and basil, respectively. All the tested isolates were pathogenic and reproduced identical symptoms to those observed in commercial glasshouses. The present study improves our understanding of Colletotrichum species associated with several hosts belonging to the Lamiaceae family, which are cultivated extensively throughout Italy for different purpose, and provides information that may be useful for an effective disease management program.

“…It was observed that symptoms produced in artificially inoculated plants were wilting, drying of branches, die-back, collar rot and death of whole plant similar under field conditions. Similarly, Washington et al (2006) recorded the occurrence of C. dematium for the first time on spinach in Australia, confirmed its pathogenicity and its host range.…”

First report of Anthracnose/collar rot caused by Colletotrichum dematium on statice (Limonium sinuatum) in Pakistan

During the month of March 2011, the incidence of anthracnose caused by Colletotrichum dematium on statice grown as ornamental plants at Ayub Agricultural Research Institute Faisalabad, Pakistan, was recorded. The characteristic symptoms were first, brownish spots on leaves and branches, and then drying of branches starting from plant tips down to the collar region, causing collar rots and leading to the death of the whole plant. C. dematium was consistently isolated from infected plants. This is the first report of anthracnose caused by C. dematium on statice plants in Pakistan.
