Hispidicarpomyces was introduced by Nakagiri (1993) is a monotypic genus which shares similar morphological features with Spathulospora. There is no sequence data available for this genus, therefore, further taxon sampling is essential to determine its phylogenetic position within the Ascomycota (Jones et al. 2015, 2019). Hispidicarpomyces galaxauricola is similar to members of Spathulospora in morphology and parasitism on marine red algae (Kohlmeyer 1973, Kohlmeyer & Kohlmeyer 1979). However, they are different in that H. galaxauricola has true hyphae growing throughout the algal frond and, in contrast, those of Spathulospora spp. are reduced-hyphoid (Kohlmeyer 1973). Further, intracellular invasion into the algal cell by an infection peg and formation of intracellular crusts can be seen in Spathulospora species, but H. galaxauricola showed only intercellular infection (Nakagiri 1993).

Type species: Hispidicarpomyces galaxauricola Nakagiri.

Other accepted species: Species Fungorum – search Hispidicarpomyces.
