Diagnostic features
Cell V obtriangular, half of the length of cell IV, often divided and proliferating into a branch of variable length (
Fig. 41F
, 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
).
