Type speciesTracylla spartinae (Peck) Tassi

NotesTracylla was introduced as a subgenus by Saccardo (1895), and raised to generic rank by Tassi (1904). The genus is typified by Tracylla spartinae observed on Spartina patens and several other grasses in Brazil, Jamaica, Philippines, Sri Lanka, Thailand and USA (Nag Raj 1993). Two other species include T. aristata and T. eucalypti. Tracylla aristata was described from Eucalyptus leaf litter collected in Australia (Cooke 1891), New Zealand and South Africa (Crous & Van der Linde 1993), and on Hakea dactyloides (Nag Raj 1993). Tracylla eucalypti was observed from leaves of Eucalyptus urophylla in Colombia (Crous et al. 2018d). The three species differ in their conidial morphology with the presence (T. spartinae:14–18 × 6–8 µm, with apical and basal appendages 11–30 µm; T. aristata: 13-17 × 2-3 µm, apical appendage 6.5-14 µm) or absence of appendages [T. eucalypti 1–1.5 µm diam, (12–)17–19(–20) × (2.5–)3 µm].
