Bolbea A.T. Buaya & Thines, gen. nov.

Index Fungorum number: MB 833722; Facesoffungi number: FoF

Etymology: Named after the Greek lake nymph Bolbe, whose parents were of oceanic origin, reflecting the marine origin of the host group and likely also the pathogen group of the organism.

Diagnosis: Differs from Atkinsiella by the lack of sacculate hyphae in culture and from Blastulidium by its much more infrequent hyphal constrictions and more regular hyphae. Differs from other members of the Leptomitales by its crustacean host.


Description: Thallus holocarpic in crustaceans, killing the host while growing, finally consuming it entirely; hyphae regular, usually 5–15 µm broad, with their cytoplasmic contents maturing into zoospores; zoospores roundish within hyphae, diplanetic; zoospore discharge from mature hyphae by short discharge tubes; asexual resting spores or oospores not observed.

Type species: Bolbea parasitica A.T. Buaya & Thines
