Natural History of Sawley and Eavestone. 237 
elevation (Lord’s Nab). A great competitor, especially on 
tree boles and outeropping roots thereof, and also upon dead 
branches of Sprucé Fir, was the crimped Parmelia physodes Ach, 
while the darker sheen of Parmelia tiliacea Ach. was likewise 
common. The frondose Evernia furfuracea Mann. thrived 
best on the tops of the gritstone walls, but tree boles were also 
another of its habitats. In the open spaces in the woodlands, 
and on soil covered boulders, species of Cladonia, especially 
C. gracilis, macilenta, pyxidata, and squamosa, were very 
beautiful and conspicuous, occurring in large sheets. The 
Eavestone and Sawley records have been kept separate ; the 
species occurring in the Eavestone area only are signified by a 
dagger ; those from Sawley only by an asterisk ; unmarked 
species denote that they occur in both areas.
