Table 1. Strains of Colletotrichum spp. studied, with collection details and GenBank accession numbers
Figure 1. The first of 430 equally most parsimonious trees obtained from a heuristic search of the combined ITS, sod2, apn2, and apn2/mat1 sequence alignment of the Graminicola species complex. Bootstrap support values above 50 % and Bayesian posterior probability values above 0.70 are shown at the nodes. Colletotrichum gloeosporioides strain CBS 112999 is used as outgroup. Numbers of types or ex-type strains are emphasized with an asterisk. The Caudatum subclade is indicated with a green bracket.
Figure 2. The first of 711 equally most parsimonious trees obtained from a heuristic search of the combined ITS, tub2, act, and gapdh sequence alignment of the Graminicola species complex. Bootstrap support values above 50 % and Bayesian posterior probability values above 0.70 are shown at the nodes. Colletotrichum gloeosporioides strain CBS 112999 is used as outgroup. Numbers of types or ex-type strains are emphasized with an asterisk. The Caudatum subclade is indicated with a blue bracket.
