THE LICHENS OF THE FAROES
Kiszka. On dolerite, Suðuroy, 8/1867,
Ro-strup (1 \Arthonia sp., in a collection
named Bacidia inundata (=Scolicio-
sporum umbrinum).
*Micarea botryoides (Nyl.) Coppins.
Toftavatn, on moss, SS 6299-3.
*M. incrassata Hedl. On soil, S-end
Sandoy, top of cliff, VA 851677. (2: Le-
cidea assimilata; 1: Lecidea alpestris
p.p.)
M. lignaria (Ach.) Hedl. Very common on
debris, 45 coll. (10; 1: Bilimbia sabule-
torum var. milliaria p.p.; 2: B. milliaria
p.p.).
*M. melaena (Nyl.) Hedl. Ryskivatn, VA
85466.
*M. nitschkeana (Lahm ex Rabenh.)
Harm. Toftavatn, on Calluna, Rostrup
1867. (1: Bilimbia sabuletorum var. mil-
liaria p.p.; 2: B. milliaria p.p.).
Micarea paratropa (Nyl.) Alstrup comb.
nov.
Basionym: Lecidea paratropa Nyl. in
Flora 52: 84, 1869. Syn.: Micarea subvio-
lascens (H. Magn.) Coppins.
On rock. 1 km W of Kvívík, SS 6248-1
and 6254-3. (1,30: Lecidea paratropá).
One sheet with 3 envelopes marked type
is found in C. 2 envelopes are from
Glyvursnes and 1 from Vardebakke.
Neither Nylander (1869) nor Rostrup
(1870) designated a holotype; the top spec-
imen from Glyvursnes is the biggest and
best preserved, and is here selected as lec-
totype. A specimen in H-Nyl (15-627) has
the name written in pencil, apparently not
by Nylander, and it represents a different
species. It is not marked as a type.
The original description gives the
hypothecium as brown, but it is purplish
giving a purplish solution with K. The thal-
lus does not react with K although the pro-
tologue said it to become yellow.
Deichmann Branth also investigated the
type and wrote “Species notha. Revera Lec.
lapicidae. Hydr. kal. thallus non flavescit,
ut afficit Nyl.”, and he did not accept the
species. The yellow colour seen by Ny-
lander probably came from bluegreens
growing between the areoles.
M. prasina Fr. Base of Larix and on moss,
Tórshavn, VA 85649 and 85650. (10).
Micarea subconfusa (Nyl.) Alstrup comb.
nov.
Basionym: Lecidea subconfusa Nyl.,
Flora 52(6): 84, 1869.
Holotype: Faeroe, Stroemoe, legit.
Rostrup (C). Two specimens are found in
C. One specimen is glued to a paper
marked with Rostrup’s handwriting:
Lecidea subconfusa Nyl., Torshavn,
Rostrup 8/67 and in red ink: specimen
primarium a Rostrup Nylandro missum. As
Tórshavn is a town situated on the island
Streymoy there is no discrepancy about the
localities mentioned in the description and
on the specimen. The other specimen is
found in an envelope marked “Lecidea sub-
confusa n. sp. (Nyl. in litt.) Thorshavn
Færøeme 8/67 E. Rostrup”. The two speci-
mens seem to originate from the same col-
lection, and Rostmp probably divided the
collection and sent only a part of it to
Nylander.
