Notes: Hiospira was established and illustrated by Moore (1962), with H. hendrickxii as the type species. Currently, Hiospira comprises two species: H. hendrickxii and H. jambosae, which were found in Brazil and Congo on Cyrtostachys rendlei, Elaeis guineensis, Jambosa vulgaris and Wallichia disticha (Moore 1962; do Brasil 1964). Hiospira is characterized by having fuscous, erect or ascending conidiophores, fuscous, and single secondary conidiophores, and loosely or tightly coiled conidia (Moore 1962). Hiospira resembles Helicodendron in having helicoid and ellipsoidal conidia, but Hiospira differs by its longer finger-like protrusions on conidiophores, and occasionally displaying chains of conidia (Linder 1929; Moore 1962).
