Species- L. filifera
Perithecium olive; length subequal to receptacle. Apex broad, darkened, and almost truncate. Lip-cells turned outward. Minute inner appendage and very elongate outer appendage (often detached as in this case) with hyaline base. Anterior margin of receptacle with distinct ‘bend’ above cell II.
On Harpalus affinis. Attachment point unclear, but likely from the crowd towards elytral base consistent with Thaxter’s monograph. Host found in urban yard, which apparently constitutes as field habitat for hosts of L. filifera.
