Remarks
First record from
Denmark
and the first after it was originally described. This species has rarely been found as mature in
Denmark
, but the immature thalli showing broad, lateral antheridia on appendage, may be easily classified. The foot consists of a lateral darker spot surrounded by a paler area (
Fig. 12H
).
