Figure a–c. Conidiophores and conidia. d–g. Conidia. (Bars= 5 μm, unless otherwise specified) Fig. 2 Stemphylium lycopersici. Maximum-likelihood (ML) tree obtained from aligned ITS sequence of the Stemphylium lycopersici and allied species.
Conidiophores Conidiophores erect, simple or branched near the base, smooth or echinulate, up to 200 μm long, 4–5.5 μm wide.
Conidiogenous cells Conidiogenous cell integrate, terminal, slightly swollen, with 1–2 percurrent proliferations.
Conidia Conidia cylindrical or obclavate, brown, echinulate, with 1–2 major darkened, constricted transverse septa and several longitudinal or oblique septa, 35–45(–50) × 15–20 µm
Note Strain 14037 shares 99.41% identity in ITS region with the ex-type strain of Stemphylium lycopersici (CBS 122639; KU850611).
This species has poor sporulation in culture. To induce sporulation, refer to the note of Pyricularia oryzae.
