Diagnostic features

Receptacle consisting of 6–9 superposed cells. All cells flattened except for the upper cell of the receptacle which is rectangular, twice or more times as long as broad, and laterally bears the perithecium (Fig. 10A, *). All cells of the receptacle, except for cell I and 1–2 cells above, dividing bilaterally to form secondary appendages, some of them giving rise to terminal, short antheridia. Cell VI triangular in section, forming an oblique base for the perithecium. [Detailed descriptions: Santamaria 2003; Majewski 2006]

Distribution and hosts

Only known from Spain (type), Poland (Majewski 2006), and Bulgaria (Rossi et al. 2019a), typically on Hydnobius, but also reported on Leiodes (Col. Leiodidae).

Remarks

First record from Denmark. The distribution of this species is patchy, from Southern to Northern Europe, probably by lack of exploration, but the record from Denmark is not surprising because of its previous record from neighbouring Poland.
