Understanding the factors that drive the evolution of pathogenic fungi is central to revealing the mechanisms of virulence and host preference, as well as developing effective disease control measures. Prerequisite to these pursuits is the accurate delimitation of species boundaries. Colletotrichum gloeosporioides s.l. is a species complex of plant pathogens and endophytic fungi for which reliable species recognition has only recently become possible through a multi-locus phylogenetic approach. By adopting an intensive regional sampling strategy encompassing multiple hosts within and beyond agricultural zones associated with cranberry (Vaccinium macrocarpon Aiton), we have integrated North America strains of Colletotrichum gloeosporioides s.l. from these habitats into a broader phylogenetic framework. We delimit species on the basis of genealogical concordance phylogenetic species recognition (GCPSR) and quantitatively assess the monophyly of delimited species at each of four nuclear loci and in the combined data set with the genealogical sorting index (gsi). Our analysis resolved two principal lineages within the species complex. Strains isolated from cranberry and sympatric host plants are distributed across both of these lineages and belong to seven distinct species or terminal clades. Strains isolated from V. macrocarpon in commercial cranberry beds belong to four species, three of which are described here as new. Another species, C. rhexiae Ellis & Everh., is epitypified. Intensive regional sampling has revealed a combination of factors, including the host species from which a strain has been isolated, the host organ of origin, and the habitat of the host species, as useful indicators of species identity in the sampled regions. We have identified three broadly distributed temperate species, C. fructivorum, C. rhexiae, and C. nupharicola, that could be useful for understanding the microevolutionary forces that may lead to species divergence in this important complex of endophytes and plant pathogens.

“…Phoulivong et al (2010) showed that C. asianum, C. fructicola, C. siamense and C. simmondsii can infect chili, guava, jujube, mango, papaya and rose apple; Yang et al (2012a) showed that C. orchidearum, C. karstii and C. siamense are not host-specific as they infected fruit of apple, chili and tomato following pathogenicity testing. Peng et al (2012) (Cai et al 2010, Noireung et al 2012, Phoulivong et al 2010b, Yang et al 2012b. Infection of fruits may be dependent on environmental factors such as variety and condition of the fruit, humidity and temperature, and the concentration of inoculum (Simmonds 1965, Freeman et al 1998, rather than which Colletotrichum species colonizes it.…”

“…However, some species of Colletotrichum have narrow host ranges. For example C. kahawae infects only coffee, C. coccodes infects on tomato and potato, C. falcatum infects only sugarcane, and C. musae infects only banana (Canon et al 2008, Freeman et al 2001, Kim et al 2009, Prihastuti et al 2009, Sreenivasapradad & Talhinhas, 2005, Yang et al 2012b. Only some isolates of C. kahawae are able to cause coffee berry disease, and are therefore of biosecurity importance (Silva et al 2012a,b) and these isolates could be distinguished using GS sequences (Weir et al 2012), Apn25L and MAT 1-2-1 (Silva et al 2012b).…”

Strains of Colletotrichum were isolated from the fruits of chili, coffee, longan, mango, papaya and rose apple, collected from orchards and markets in Laos and Thailand. Isolates were identified using morphological characters, colony growth rate, and confirmed with DNA sequence data analysis of combined multi-gene loci. Pathogenicity testing of ten strains representing five species of Colletotrichum was carried out on Capsicum sp. (chili), Carica papaya (papaya), Citrus reticulata (orange), Eugenia javanica (rose apple), Mangifera indica (mango) and Psidium guajava (guava) using a wound drop technique. Pathogenicity and potential for cross infectivity of Colletotrichum asianum, C. cordylinicola, C. fructicola, C. saimense and C. simmondsii were tested on the hosts. The Colletotrichum strains belonging to different species tested were generally shown to infect a wide host range.

“…Appressoria were induced by depositing conidia in distilled water (1.0 × 10 6 conidia/mL) on a microscopic glass slide placed inside a Petri dish containing 2 to 3 layers of filter paper moistened with sterile distilled water, and incubated at 28°C. After incubation for 7 to 8 h, conidial appressoria were observed under a Nikon light microscope (Yang et al 2012). Three replicate cultures of each isolate were investigated.…”

Colletotrichum truncatum was for the first time found to cause severe anthracnose of Chinese flowering cabbage (Brassica parachinensis L. H. Bailey) (Cruciferae), in Guangdong province, China. Identification of this Colletotrichum species with curved conidia was based on morphological and cultural characteristics and multi-gene phylogenetic analysis, which showed that this fungus belongs to C. truncatum. Artificially inoculated seedlings of Chinese flowering cabbage showed typical symptoms of anthracnose similar to those observed in the field. To understand the cross-pathogenicity of C. truncatum isolates infecting Chinese flowering cabbage and soybean, artificial inoculations on both hosts were carried out and the results indicated that the isolates of Chinese flowering cabbage could infect soybean, and vice versa. C. truncatum was consistently re-isolated from the artificially infected tissues of both hosts. Furthermore, a comparison of the effects of environmental factors on C. truncatum isolates CBP001 and XST01 from Chinese flowering cabbage and soybean, respectively, demonstrated that these two isolates have similar biological characteristics. Therefore, it is concluded that C. truncatum is the causal agent of anthracnose of Chinese flowering cabbage.
