[Detailed descriptions: Thaxter 1908 ; Benjamin & Shanor 1951 ; Sugiyama 1973 ; Majewski 1994b ; Santamaria 2003 ] Distribution and hosts Usually found on species of Lathrobium and Lobrathium (Col. Staphylinidae Paederinae ), less commonly on other staphylinids like Hom(a)eotarsus Hochhuth, 1851 ( Benjamin & Shanor 1951 ), Xantholinus Dejean, 1821 ( Scheloske 1969 , probably Megalinus Mulsant & Rey, 1877 according to Tavares 1985 ), Pseudolathra Casey, 1905 ( Rossi 1975 ) ; maybe fortuitously on Col. Carabidae like Patrobus Dejean, 1821 ( Scheloske 1969 ) and Pterostichus Bonelli, 1810 ( De Kesel & Gerstmans 2011 ). Widespread in Europe ( United Kingdom , France , Switzerland , the Netherlands , Belgium , Germany , former Yugoslavia , Poland , Italy , Finland , Hungary , Spain , Latvia ), Africa ( Algeria , Morocco ), Asia ( Japan ), North and South America ( USA , Bolivia ) ( Majewski 2008 ). Recently reported also from Czech Republic ( Rossi et al. 2010 ), Sweden ( Huggert 2010 ), Ecuador ( Bernardi et al. 2014 ), Greece ( Goldmann & Weir 2018 ), and Bulgaria ( Rossi et al. 2019a ).

Remarks First record from Denmark . Very variable in receptacle length and width, as well as in the number of appendages and perithecia, from one perithecium on narrow long ( Fig. 4A ), or narrow short ( Fig. 4B ) receptacles, to large and broad thalli bearing numerous perithecia ( Fig. 4C ). There is no relation between these thallus shapes and different species of Lathrobium , although at least part of the variation seems to be geographical. Further studies with more modern integrative taxonomical techniques should be carried out to reveal if there is more than one species in the genus. Antheridia simple, grouped by 2 on a short simple branchlet supported by cell VII as is seen in Fig. 4D (an, VII).
