8. C. juiliperina, (L.) Ach. On cypress in swamps.

Dawson, in “Notes on the Flora of the White Mountains,” in the 
Canadian Naturalist for April, 1868, p. 8S, relates that at the un¬ 
veiling of an Egyptian mummy in Montreal some time previously, 
quantities of this lichen, which he thinks was imported from Lebanon 
or Macedonia for such uses, were wrapped around the body to pre¬ 
serve the odor of the spices. Specimens were sent to Tuckerman, 
and were identified by him. 
2. E. prunastri, (L.) Ach. On rails and stones in walls. Rare 
and sterile. Our plant was referred here by Tuckerman. but it seems 
to be the same as E. thamnodes , Nyl. Behr. p. 19.

b. ceratina , Seiner. 
c. dasypoga , Fr. A specimen on rock is provided with con¬ 
vex cephalodia, which seem to take the place of apothecia. 
One of our most common Lichens, especially a on trees, more rarely 
on rails and stones. As Payot says in his Guide du Lichenologue 
an Mt. Blanc , p. 5, it is very inflammable; and he relates an anec¬ 
dote of a young man who, while collecting it at the top of a tree, 
struck a match to light his pipe. Throwing it awav, it set fire to the 
Usnea, and he was frightfully burned, and could only escape by throw¬ 
ing himself from the tree into the snow. I have amused mvself 
while in the swamps by setting fire to it on the lower branches of a 
tree, and seeing how rapidly it would burn to the top. But I re¬ 
mained on terra firma. 
2. u. tricliodea, Ach. On trees in swamps.
