Is this lichen Peltigera neopolydactyla:

http://www.danbbs.dk/~gro_poul/billedkasse.htm

The foto is from 2003.06.14 from Alleroed - ca. 15. km. N. Copenhagen,
Denmark, in a former military area. It grows on calcerous (?) gravel
covered with 2-4 cm. humus.

If I am right, it is at new species for Denmark.

Did you keep dried specimens? If not, can you find it again? If so,
you probably should send them to a lichen expert [perhaps one who has
recently published something on systematics of Peltigera], or to a
lichen herbarium, for positive ID. Such specimens will likely be
needed to document any important new distribution records.

Searching for "Peltigera neopolydactyla" didn't find too much of

Title: Addition to the chemistry, ecology and distribution of
Peltigera melanorrhiza and P. neopolydactyla.
Author, Editor, Inventor: Martinez-Isabel; Burgaz-Ana-Rosa
Author Address: Dep. Biol. Veg. I, Fac. Biol., Univ. Complutense,

Source: Mycotaxon-. 1997; 63 (0) 389-394.
Abstract: New data about the chemistry, ecology and distribution of
two species belonging to the Peltigera hymenina group (Peltigera
melanorrhiza and P. neopolydactyla) are given for Europe. A new
chemotype within P. melanorrhiza is described and this taxon is
recorded as new for continental Europe. A discussion about the P.
neopolydactyla morphotypes and chemotypes is given, its distribution
area is shown to extend towards temperate and oceanic areas in
southwestern Europe.

Title: Peltigera monticola recorded from Sweden, and some other notes
and comments on the genus Peltigera.

Source: Svensk-Botanisk-Tidskrift. 1999; 93 (5-6): 279-285.
Language: Swedish; Non-English
Language of Summary: English; Swedish
Abstract: Peltigera monticola Vitik., previously only known from
southern and central Europe, has been found in subalpine birch forest
in Lycksele lappmark (c. Lappland), Sweden. P. didactyla var.
extenuata is reported from several Swedish localities and is suggested
to be approved as an indicator of forest sites with conservation values.
P. occidentalis, usually treated under P. neopolydactyla agg., is
reported from subalpine birch forest in northern Sweden. The characters
used to separate these three taxa from their closest allies are
presented. Furthermore, P. degenii and P. neckeri are reported as new
to Lycksele lappmark.
