Diagnostic features

Cell V obtriangular, half of the length of cell IV, often divided and proliferating into a branch of variable length ( Fig. 41F View Fig , arrow) which may support some antheridia. Insertion cell separated from the perithecium. Outer appendage once or twice branched above the basal cell, sometimes bearing solitary, lateral antheridia. Inner appendage, in young thalli, consisting of two branches bearing paired antheridia arising from the basal cell; in mature thalli replaced with long sterile appendages, similar to the outers. Basal cell of inner appendage half as long and as broad than basal cell of outer appendage. [Detailed descriptions: Thaxter 1908; Majewski 1994b; Santamaria 1998]

Distribution and hosts

Typically grows on species of Pterostichus of the subgenus Melanius (often as Pseudomaseus Chaudoir, 1838 or Platysma ), but also reported on other Col. Carabidae like Patrobus , Lagarus , Elaphrus , Stomis , Loricera , Anchomenus , Oxycentrus Chaudoir, 1854 , and Nebria . Known in Europe, North and Central America, and Asia. Given the confusion with L. pterostichi Thaxt. for years, it is wise to refer to the work of Rossi & Weir (1997) who unravelled the problem, and we agree with them that the number of misidentifications makes it impossible to determine its geographical distribution with certainty. Recently reported from Austria ( Rossi & Christian 2020) and the Netherlands ( Haelewaters & De Kesel 2020).

Remarks

First record from Denmark. Often confused with L. flagellata , L. proliferans Thaxt. and L. pterostichi ( Majewski 1994b) . The latter probably does not exist in Europe ( Rossi & Weir 1997).
