Diagnostic features

Appendage unbranched, sometimes very elongated (up to 460 µm, Majewski 1994b), consisting of several superposed and variably elongated cells. Antheridia stout, sessile or subsessile (on small supporting cells) ( Fig. 51A , arrows), not rarely on a short, ramified branch ( Fig. 51B , arrow) borne on the inner side of the lower cells of appendage, including cell III ( Fig. 51A , III) or, less commonly, above it up to the 10 th cell and even beyond. [Detailed descriptions: Majewski 1994b; Castaldo et al. 2004]

Distribution and hosts

Reported on Pselaphinae beetles (Col. Staphylinidae ), mostly belonging to the genus Brachygluta , from Algeria (type) and Europe: Italy, Greece, Poland, France, Finland, United Kingdom, Germany ( Majewski 2008), Hungary ( Bánhegyi et al. 1985), Belgium ( De Kesel & Rammeloo 1992), Sweden ( Huggert 2010), the Netherlands (Haelewaters et al. 2014). Records on other genera different from Brachygluta should be checked for the identity of the fungus: Bryaxis , Reichenbachia Leach, 1826 , Rybaxis Saulcy, 1876 , Trissemus Jeannel, 1949 , Faronus Aubé, 1844 , Tychus , and Bythinus Leach, 1817 . Records on Bryaxis probably refer to Cryptandromyces bryaxidis ( Maire 1916b; Scheloske 1969; Santamaria 1989). On Tychus we found Cryptandromyces bibloplecti (see above). On Faronus, SS has found immature thalli similar to Cryptandromyces euplecti from Spain (unpublished).

Remarks

First record from Denmark, where it is very common. Castaldo et al. (2004) brought order to the longstanding confusion between C. brachyglutae and PeYerimhofiella elegans .
