Fig. 3 Maximum-likelihood (ML) tree obtained from aligned ITS, GADPH, TUB2 sequence of the Colletotrichum plurivorum and allied species.
Colonies Colonies on PDA attaining 66-mm after 5 days at 25 °C, floccose, pale olivaceous grey with white margin, reverse dark olivaceous.
Conidia Conidia hyaline, aseptate, falcate, 14–18 × 5–6 µm, microcyclic conidiation often present.
Setae Setae smooth or verruculose, dark brown, tapering toward tip, 3.5–5 µm wide at the base, 100–170 µm long.
Appressoria Appressoria solitary or in group, bullet-shape or irregularly lobed, 9–13 × 5–9 µm.
Note Colletotrichum plurivorum is phylogenetically and morphologically close to C. cliviicola. Damm et al. (2019) proposed C. plurivorum as a new species based on differences in nucleotides of GPD, TUB, and HIS3 genes, host range, with fast growth rate and sexual morph, and without microcyclic conidiation. However, strain 13062 and 18058 clustered in the C. plurivorum clade according to the ITS, GPD, and TUB multilocus phylogenetic phylogram did produce microcyclic conidiation, without sexual morph. Therefore, the separation of both species needs further study.
