“…Note that one of the isolates metabolically and genetically typical C. kahawae subsp. kahawae ( CBS 982.69 ) was reported by Gielink & Vermeulen ( 1983 ) to be non-pathogenic to coffee, but we have not independently checked this result.…”

“… Waller et al 1993 stated that C. kahawae was not known to form ascospores. However, Gielink & Vermeulen ( 1983 ) observed the production of perithecia on coffee berries that had been inoculated with CBD-causing isolates, many months after inoculation and death of the berries. At least one of the isolates that they cited with this biology, CBS 135.30 , has the GS sequence typical of C. kahawae subsp.…”

The limit of the Colletotrichum gloeosporioides species complex is defined genetically, based on a strongly supported clade within the Colletotrichum ITS gene tree. All taxa accepted within this clade are morphologically more or less typical of the broadly defined C. gloeosporioides, as it has been applied in the literature for the past 50 years. We accept 22 species plus one subspecies within the C. gloeosporioides complex. These include C. asianum, C. cordylinicola, C. fructicola, C. gloeosporioides, C. horii, C. kahawae subsp. kahawae, C. musae, C. nupharicola, C. psidii, C. siamense, C. theobromicola, C. tropicale, and C. xanthorrhoeae, along with the taxa described here as new, C. aenigma, C. aeschynomenes, C. alatae, C. alienum, C. aotearoa, C. clidemiae, C. kahawae subsp. ciggaro, C. salsolae, and C. ti, plus the nom. nov. C. queenslandicum (for C. gloeosporioides var. minus). All of the taxa are defined genetically on the basis of multi-gene phylogenies. Brief morphological descriptions are provided for species where no modern description is available. Many of the species are unable to be reliably distinguished using ITS, the official barcoding gene for fungi. Particularly problematic are a set of species genetically close to C. musae and another set of species genetically close to C. kahawae, referred to here as the Musae clade and the Kahawae clade, respectively. Each clade contains several species that are phylogenetically well supported in multi-gene analyses, but within the clades branch lengths are short because of the small number of phylogenetically informative characters, and in a few cases individual gene trees are incongruent. Some single genes or combinations of genes, such as glyceraldehyde-3-phosphate dehydrogenase and glutamine synthetase, can be used to reliably distinguish most taxa and will need to be developed as secondary barcodes for species level identification, which is important because many of these fungi are of biosecurity significance. In addition to the accepted species, notes are provided for names where a possible close relationship with C. gloeosporioides sensu lato has been suggested in the recent literature, along with all subspecific taxa and formae speciales within C. gloeosporioides and its putative teleomorph Glomerella cingulata.Taxonomic novelties:Name replacement - C. queenslandicum B.

“…One of the two strains from western Kenya that are assigned to C. acutatum s. str. is derived from a suspected disease symptom on a coffee berry from Kenya that did not cause CBD ( Gielink & Vermeulen, 1983 ). One of the endophytic strains from Coffea robusta in Brazil studied by Sette et al ( 2006 ) showing antimicrobial activity against Staphylococcus aureus belongs to the C. acutatum species complex; since only a short ITS sequence of this strain was generated (DQ123614), the species cannot be identified.…”

Colletotrichum acutatum is known as an important anthracnose pathogen of a wide range of host plants worldwide. Numerous studies have reported subgroups within the C. acutatum species complex. Multilocus molecular phylogenetic analysis (ITS, ACT, TUB2, CHS-1, GAPDH, HIS3) of 331 strains previously identified as C. acutatum and other related taxa, including strains from numerous hosts with wide geographic distributions, confirmed the molecular groups previously recognised and identified a series of novel taxa. Thirty-one species are accepted, of which 21 have not previously been recognised. Colletotrichum orchidophilum clusters basal to the C. acutatum species complex. There is a high phenotypic diversity within this complex, and some of the species appear to have preferences to specific hosts or geographical regions. Others appear to be plurivorous and are present in multiple regions. In this study, only C. salicis and C. rhombiforme formed sexual morphs in culture, although sexual morphs have been described from other taxa (especially as laboratory crosses), and there is evidence of hybridisation between different species. One species with similar morphology to C. acutatum but not belonging to this species complex was also described here as new, namely C. pseudoacutatum.Taxonomic novelties:New combinations - Colletotrichum limetticola (R.E.

“…From 1974From until 1980 isolates, alleged to be C. coffeanum, from South and Central American coffee growing countries were tested in the Netherlands for their ability to induce CBD symptoms on coffee berries and seedlings. This material was compared with African CBD isolates (Gielink and Vermeulen, 1983). The association of G. cingulata not only with non-pathogenic Colletotrichum isolates but also with some CBD pathogens was repeatedly observed in the pathogenicity experiments.…”

Abslrac!In earlier experiments the perfect state, Glomerella cingulata, had been found associated with Colletotrichurn coffeanum. As the linkage between G. cingulata and the coffee berry disease (CBD) pathogen had still been doubtful, further investigations were done. It was found that mono-spore cultures derived from G. cingulata perithecia from two different CBD isolates were not Compatible. This would suggest genetic differences between these two CBD pathogens.Preliminary tests with mono-ascospore isolates of one G. cingulata source resulted in a wide range of segregation types. It has not yet been possible to obtain a conidial form from G.cingulata, which has the morphological and pathogenic characteristics of C. coffeanum. The results of the experiments suggest, however, that a CBD pathogen may arise through genetic segregation from a G. cingulata state.
