Mycetomorpha, Potts, 1912

Høeg, Jens T., Noever, Christoph, Rees, David J., Crandall, Keith A. & Glenner, Henrik, 2020, A new molecular phylogeny-based taxonomy of parasitic barnacles (Crustacea: Cirripedia: Rhizocephala), Zoological Journal of the Linnean Society 190, pp. 632-653 : 642

Genera: Mycetomorpha (two spp.).

Remarks: The genus contains only two species, of which Mycetomorpha albatrossi Høeg & Rybakov, 1996b is poorly known, but the shape of the externa in this genus is unique ( Høeg & Rybakov, 1996b). The family was previously placed in the now abandoned Akentrogonida , but Høeg et al. (2019) clearly placed Mycetomorpha vancouverensis as sister group to Peltogaster paguri and Lernaeodiscus porcellanae Müller, 1862 . Compared with our analysis, the position in the study by Høeg et al. (2019) therefore shows that Mycetomorpha is located somewhere among the taxa clustered under node 4 in Figure 3. Until a more refined analysis including more former peltogastrids and lernaeodiscids is available, we choose to retain this morphologically unusual genus as a separate family.
