TL;DR: The limit of the Colletotrichum gloeosporioides species complex is defined genetically, based on a strongly supported clade within the Col letteredum ITS gene tree, as well as all taxa accepted within this clade, as it has been applied in the literature for the past 50 years.

TL;DR: A review is provided of the current state of understanding of Colletotrichum systematics, focusing on species-level data and the major clades, and the taxonomic placement of the genus is discussed.

TL;DR: Multilocus molecular phylogenetic analysis 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.

TL;DR: Tolerance, defined as the ability to compensate in part for fitness decrements caused by disease, was found to involve fitness costs and Halfsib families that were more tolerant of disease had lower fitness in the absence of disease.
Abstract: A major assumption of models of the evolution of plant resistance to disease is that plant resistance involves fitness costs. To test this assumption, a field experiment was performed so that a quantitative-genetic analysis could be used to detect fitness costs to Ipomoea purpurea of resistance to different fungal isolates of Colletotrichum dematium, a pathogenic fungus causing the disease anthracnose. This experiment yielded no evidence that resistance to anthracnose involves direct fitness costs. Nevertheless, trade-offs in plant fitness that were unrelated to resistance were detected between different disease environments. Tolerance, defined as the ability to compensate in part for fitness decrements caused by disease, was found to involve fitness costs. Halfsib families that were more tolerant of disease had lower fitness in the absence of disease. The possibility that the cost of tolerance could obscure fitness costs of resistance is explored.

TL;DR: Seven of the new species are only known from New Zealand, perhaps reflecting a sampling bias, and the new combination C. phyllanthi was made, and C. dracaenae Petch was epitypified and the name replaced with C. petchii.
