METZGERIA Raddi 
METZGERIA FURCATA (L.) Lindb. 
Widely distributed from Dumfries to Shetland, and 
generally common on the low-lying ground where there is 
some degree of shelter, but there are many sheltered 
localities where it is by no means common although the 
surrounding conditions appear equally favourable. In the 
Lowlands it is rather common in woodland districts, but 
becomes rare in the valleys above an altitude of 800 ft., as 
in the Upper Clyde and Upper Tweed districts. It is 
common in the East and West Highlands and Inner 
Hebrides, but less so in the extreme north of the mainland. 
It is rare on the hills and doubtfully ascends above 1800 ft. 
alt. It usually occurs on trees in the Lowlands, though 
not rare on rocks. In the Highlands it is found equally 
common on rocks and on trees. Although preferring some 
shelter, this species is frequently seen on exposed rocks, 
especially on the sea-shore. It grows on various formations 
and is sometimes common on limestone. Fruit is rare, and 
is mature from September to February.
