IQI3- KnowIvKvS. — Lichens of Saltas, 199 
IV. LICHENS. 
BY M. C. KNOWLES. 
The Lichens of the district Li of Mr. Adams' sub- 
divisions of Ireland (which consists of the counties of 
Wexford, Carlo w and Kilkenny), have received very little 
attention, only 31 species having been recorded from this 
area. It was a great satisfaction, therefore, to go through 
the material collected by Canon Lett and Mr. Praeger on 
the vSaltee Islands, and to find that the majority of the 
species were additions to the district. 
/Altogether the material yielded 86 species, 5 sub-species, 
7 varieties and 5 forms ; of these, 75 species and all the 
sub-species, varieties and forms are new to Li. 
In the hst which follows, all but the undermentioned are 
new to x\dams' province Li : — 
Lichina pygmaea. Physcia stellaris. 
Sphaerophorus coralloides. Lecanora parella. 
Cladonia pyxidata. Lecidea parasema. 
Cladina sylvatica. Buellia stellulata.
