Notes: Inesiosporium was erected by Castañeda Ruíz and Gams (1997), with I. longispirale as the type species based on its unique morphologies of conidiophores and conidia. Inesiosporium comprises two species: I. longispirale (Zalerion longispiralis) and I. mauiense (Ceratophorum mauiense), which were found from Calophyllum antillanum and Eucalyptus saligna in Cuba and America, respectively (Sutton and Jr 1981; Castañeda Ruíz and Gams 1997). Inesiosporium shares similarities with Helicoon in having septate and helicoid conidia but differs by having conidia that are mostly loosely coiled and not barrel-shaped (Castañeda Ruíz and Gams 1997). Inesiosporium is characterized by monoblastic, T-shaped conidiogenous cells, and brown to olivaceous, multi-septate conidia that have repeated coils in three planes, or that are loosely coiled (Sutton and Jr 1981; Castañeda Ruíz and Gams 1997).
