Diagnostic features
Basal cell of appendage slightly darker, supporting a series of 3–10 flattened, oblique, dorsally almost inflated cells, each giving rise to rather elongated antheridia on the inner margin. Perithecium with an oval venter, showing distal knobs below the neck (
Fig. 57K
) and a well-distinguished, slightly bent, gradually tapering neck ending in a distinct, asymmetrical tip which shows two protruding lips. [Detailed descriptions:

Remarks
First record from
Denmark
. This species may be difficult to distinguish from
S. crassicollis
in the absence of the four knobs on the perithecial venter as in
S. divergatus
.
