The Trichoderma koningii aggregate species
The morphological concept of Trichoderma koningii is found to
include several species that differ from each other in details of phenotype
(including conidium morphology, growth rate) and biogeography. Phylogenetic
analysis utilizing partial sequences of the translation-elongation factor 1
alpha (tef1), as well as fragments of actin and calmodulin genes,
indicate that phenotypic characters typical of T. koningii evolved
independently in three well-separated main lineages. Combined molecular and
phenotype data lead to the development of a taxonomy with the recognition of
twelve taxonomic species and one variety within the three lineages. These
lineages include: (1) T. koningii and T. ovalisporum and the
new species T. caribbaeum var. caribbaeum, T. caribbaeum
var. aequatoriale, T. dorotheae, T. dingleyae, T. intricatum, T.
koningiopsis, T. petersenii and T. taiwanense; (2) the new
species T. rogersonii and T. austrokoningii, and (3) the new
anamorph T. stilbohypoxyli
