MB#180484 Fig. 30B Anales del Museo Nacional de Historia Natural de Buenos Aires 26: 464 ( Spegazzini 1915a ). – Type : “ Sulle elitre del Elaphrus cupreus originario del Belgio (Coll. Mus. Civ. Genova, n.21)”; LPS . [ Belgium ] Laboulbenia buehlmannii Poelt ( Poelt 1952: 116 ) [MB#299200] Laboulbenia bänningeri Baumgartner ( Baumgartner 1951: 32 r) (nom. inval., as L. Bännigeri ) [Not registered in MycoBank] Diagnostic features Outer appendage once ramified into two subequal branches above the second cell. Perithecium asymmetric with the ventral side distinctly more convex than the dorsal side; perithecial tip large with an almost flattened apex. [Detailed description: Majewski 1994b ] Distribution and hosts Known on Elaphrus (Col. Carabidae ) from Europe : Belgium ( type ), Finland , France , Germany , Hungary , Poland , Sweden , Russia ( Santamaria et al. 1991 ), Latvia ( De Kesel & Krastina De Kesel 2006 ), Switzerland ( Hoess & Senn-Irlet 2009 ), Czech Republic ( Rossi et al. 2010 ). Also reported on Nebria ochotica Sahlberg from China ( Lee & Lim 2000 ), a record that requires confirmation. Rostrup (1916) mentioned the host but not the fungus name from Denmark .

Remarks First record from Denmark . Rossi et al. (2010) characterized well this species, which is difficult to separate morphologically from L. flagellata except for the flattened and large perithecial apex. Laboulbenia elaphricola J. Siemaszko & Siemaszko (1928) , sometimes included among the synonyms of L. elaphri , is a distinct species ( De Kesel & Krastina De Kesel 2006 ; Rossi & Christian 2020 ).
