191 3- KnowlES. — Lichens of Sa/tees. 201 
Physcia flavicans, DC. — Very common, forming large 
orange -yellow patches on the stems and twigs of heather, 
associated with Ramalina farinacea, Parmelia pcrlata and 
P. caper ata. 
Lecanora murorum, Ach., subsp. decij^iens, Nyl. — The 
specimens seen of this sub-species were mainly barren 
growths similar to those found at Howth. This is the 
second Irish record for the sub-species. 
L. cacsionifa and L. Turneriana, Nyl. — Rare ; the only 
previous record for these two species from the east coast is 
Howth. 
L. subexigua, Nyl. — Frequent; the second record for 
Ireland. 
L. proseckoides, Nyl. — Frequent. This species was asso- 
ciated with Verrucaria maura, V. scotina, Rhizocarpon 
alhoatrum, and Lecanora lobulata, and evidently occupied the 
same place on the shore, among the semi -marine lichens, that 
it does on the Howth coasts. It was also interesting, as on 
the Howth coasts, to find that it was the host of Arthonia 
varians. The usual host of this parasitic lichen is, according 
to the " Monograph of British Lichens," Lecanora glaucoma, 
and it only rarely occurs on L. prosechoides. On the Howth 
coasts A. varians was extremely abundant on L. prose- 
choides, and it is also plentiful on the specimens examined 
from the Saltee Islands. 
Lecidea latypea, Ach. — Rare; the only previous Irish 
record for this species is Clare Island. 
L. auriculata, Th. Fr. — Rare 
record is Achill.
