The Colletotrichum gloeosporioides species complex

Fig. 2 from the paper, types of species within the complexThe major publication of my postdoc is now out — all 65 pages of it — in Studies in Mycology. In this publication we review the taxonomy of the fungus commonly known as Colletotrichum gloeosporioides, and reveal that is a complex (or species aggregate) of 22 different species. We also recognise one subspecies, and informally recognise another “species” at the f. sp. level (pending further research).

This classifications were mostly based on DNA sequence phylogenies, but our species concept was broader than used previously, for example we consider C. hymenocallidis and C. jasmini-sambac to be synonyms of C. siamense.

This publication should be useful for plant pathologists, particulary those doing pathology studies that in the past may have been confused by the previous very broad concept for C. gloeosporioides.

Here is a list of names that we currently accept in the complex. The names in bold are new taxa described in this paper:

  • C. aenigma
  • C. aeschynomenes
  • C. alatae
  • C. alienum
  • C. aotearoa
  • C. asianum
  • C. clidemiae
  • C. cordylinicola
  • C. fructicola
  • C. gloeosporioides
  • C. horii
  • C. kahawae subsp. ciggaro
  • C. kahawae subsp. kahawae
  • C. musae
  • C. nupharicola
  • C. psidii
  • C. queenslandicum
  • C. salsolae
  • C. siamense
  • C. theobromicola
  • C. ti
  • C. tropicale
  • C. xanthorrhoeae
  • G. cingulata f. sp. camelliae
