Diagnostic features

Main receptacle axis consisting of 6–23 cells. Appendages of type “a” and “b” very similar, consisting of 3–5 brownish cells. Those of type “b” mostly abundant, surrounding ± the base of the perithecium. Appendages of type “c” consisting of a solitary flask-shaped, somewhat falcate antheridium, above a darkened supporting cell, which is separated from cells of the tertiary receptacle by a dark and constricted septum ( Fig. 17A View Fig , *). Perithecium rather stout; septa between wall cells slightly prominent. [Detailed descriptions: Thaxter 1908; Santamaria 1989; Majewski 1994b; De Kesel 2002]

Distribution and hosts

Occurs on species of the genus Trechus and Epaphius Leach, 1819 (Col. Carabidae ), including caveinhabiting and surface species.According to Santamaria et al. (1991) appears to be widespread in Europe ( Austria, Bulgaria, France, Germany, Hungary, Italy, Poland, Portugal, Spain, Sweden, Russia), Canary Islands, Madeira, Morocco and Turkey. Also from Bosnia-Herzegovina ( Balazuc 1971d). Reported later from Belgium ( De Kesel & Rammeloo 1992), United Kingdom ( Weir 1994), Czech Republic ( Rossi & Máca 2006), Denmark ( Høier 2009), Switzerland ( Hoess & Senn-Irlet 2009), and the Netherlands ( Haelewaters & De Kesel 2020).

Remarks

There are no important differences between thalli found on surface beetles (type specimens) and those collected on cave beetles (described as R. bolivarii , R. reymondii and R. vayssierei ). The species is very common in Denmark.
