Uppsala, Eklundshov, IV.1866, Th. M. Fries<br />
(uPS)).<br />
It is usually collected on trunks of solitary<br />
trees in open situations, at churchyards, in<br />
gardens and parks, along alleys etc. It is preferably<br />
growing at the base of trees. Another<br />
common substrate is at the base of Alnus glutinosa<br />
in more or less exposed situations along<br />
streams and lakes.<br />
Associated species are: Bacidia rubella,<br />
Buellia punctata, Caloplaca cerina, C. chlorina,<br />
C. chrysophthalma, Candellariella xanthostigma,<br />
Cladonia coniocraea, Lecanora<br />

P. distona, P. enteroxantha, Ramalina<br />
pollinaria (Gotland), R. fainacea, Xanthoria<br />
parietina and X. potycafpa.<br />
Distribution<br />
C. obscurella has a scattered distribution in<br />
southern Sweden (Figure 1) up to Limes<br />
Norrlandicus. The absence of records from<br />
south and southeast Sweden might reflect the<br />
lack of field investigations. The Nonregian<br />
distribution was recently mapped by TOnsberg<br />
(L99z). In addition we have also seen material<br />
from central Europe.<br />
A complete list of specimens examined can<br />
be obtained from the authors.<br />
Exsiccates<br />
Arnold Lich. Mon. Exs. 377 (H) as "Blastenia<br />
obscurella ". Kiirber Lich. Sel. Germ. 185 (M)<br />
as "Blastenia obscurella". Material of this<br />
exsiccate in O has yellowish, K+ red apothecia<br />
with a greyish proper margin and minute<br />
soralia. This is probably C. chlorina. Larbala-<br />
