surrounding Monadnock, only forty- five miles to the southeast. The genera 
Umbilicaria and Stereocaulon, and other rock-loving forms are therefore 
poorly represented. An abundance of hard wood covers even the upper 
slopes, and fills the deep ravines that here and there seam its sides. Only 
on the uppermost slopes do the conifers predominate. 
The mountain is surrounded with spurs and foothill crests and ridges, 
unlike the cold and almost isolated cone of Monadnock. It is a tradition 
among the native farmers that the early settlers burned the timber off the 
upper ledges of Monadnock to destroy a refuge of wolves. 
The lichens here listed were collected from August 24 to 26, 1909, about 
the base of this mountain along Mill brook from Windsor to Dudley’s trail, 
including those secured on one ascent of the mountain on August 25. Of 
course the list does not claim to be complete, but will serve to show what the 
general character of the lichen flora is, and for what species not included 
here, other collectors may search. Very little attention was paid to collect- 
ing anything but foliose and fruticose forms. 
Examples of all specimens listed are in my herbarium. Duplicates of 
seven are distributed in Lichenes Novae Angliae (Nos. 35, 36, 37, 38, 40, 44, 
49). For examination of the specimens representing the genera Cladonia 
and Stereocaiilon I am indebted to Dr. Lincoln W. Riddle. To Messrs. A. 
Avery Hallock and Francis J. Bassett I am also indebted for much kind 
assistance in collecting. 
1. Rainalina calicaj'is f astigiata Fr. One fertile meagre specimen, all 
that was observed, collected on a deciduous tree near the mountain’s 
summit. 
2. Cetraria ciliaris (Ach.) Tuck. Uncommon, collected in fruit near 
summit. 
3. Cetraria lacunosa Ach. Common, collected in fruit on conifers. 
4. Cetraria glaiica (L.) Ach. Rare, collected sterile on twigs. This 
plant as represented in New England needs much study, being very 
unlike the glauca of the Pacific coast. All the eastern plants 
seem more referable to the variety fit sea (Flot.) without reference to 
age or substrata. 
5. ' Cetraria Oa/eesiana Tnck. Common or almost abundant. Collected on 
all growths and rocks, rarely in fruit. 
6. Cetraria juniperina Pinastri Ach. Common, collected sterile about 
3000 ft. on coniferous twigs, and on rocks. 
7. Evernia furfuracea (L.) Mann. Not uncommon, collected sterile near 
the summit.
