Notes: Delortia was established by Patouillard (1888), and typified by D. palmicola from palms in Venezuela. Delortia palmicola is characterized by gelatinous and white sporodochia, slender, hyaline, septate conidiophores that are abruptly swollen at the tips, and septate, hyaline, non-hygroscopic conidia that are coiled in two planes (Linder 1929). Delortia resembles Hobsonia in producing helicoid conidia in sporodochia. The conidia of Delortia differ from Hobsonia in producing multiseptate, proliferating and helicoid conidia which coiled in three dimensions (Martin 1959). Delortia comprises two species: D. brasiliensis and D. palmicola (Linder 1929; Rick 1960; Index Fungorum 2024). However, no further description or introduction is available for D. brasiliensis (Pirozynski 1972; Goh and Hyde 1997).
