39 . Parmelia saxatilis furfuracea Schaer. Five specimens, three 
fertile, three labelled “ saxatilis ,” and two unlabelled belong here. One 
specimen labelled “ P. saxatilis, omphalodes ” is Physcia pulverulenta 
leucoleiptes . 
40. Parmelia physodes (L.) Ach. Six specimens, one fertile. Four are 
labelled enteromorpha, all belong here. The forms platyphylla and labrosa 
are represented if recognized. One small unlabelled specimen probably 
belongs here. 
41 . Parmelia physodes vittata Ach. Two infertile specimens, both 
labelled enteromorpha (and one specimen of the original collection made in 
April, 1906) belong here. If the form hypotrypodes Nyl. be admitted these 
belong with it: 
(?) Parmelia colpodes (Ach.) Nyl. Five fertile specimens. One had 
been labelled ^physodes , and corrected — though its identity as no 
spores are found is still doubtful. I do not believe these speci- 
mens were collected in this region, nor the following: 
Parmelia pertusa (Schrank.) Schaer. Six sterile specimens. Five 
are labelled “ terebrata,” and one corrected to “ pertusa .” Fourof 
the above are labelled with the remarks “holes” or “ holes bored.” 
42 Parmelia olivacea (L.) Ach. Two fertile specimens labelled thus, 
belong here. (Fitzwilliam, common.) 
43 . Parmelia olivacea aspidota Ach. Two fertile specimens, one 
labelled thus, the other “ olivacea,” belong here. 
44 . Parmelia olivacea panniformis Nyl. One sterile specimen thus 
labelled and one labelled “ aspidota ,” belong here. 
45 . Parmelia olivacea sorediata (Ach ) Nyl. Two sterile specimens, 
(The specimen formerly questionably referred here is so worn that its abso- 
lute determination is impossible.) 
46 . Parmelia stygia (L.) Ach. Nine specimens, four fertile, and 
labelled. Two are from Monadnock, one from “ Huggins Hill,” and one 
from “ Mt. Carrigan.” (I collected on the upper bare ledges of Monadnock, 
on Nov. 3, 1907, this lichen, No. 571. It grows abundantly but I did not 
find it fruited. Also reported from Mt. Monadnock, J. L. Russell, see 
Tuckerm. Syn. 1882, p. .63.) 
47. Parmelia caperata (L.) Ach. Four specimens, three labelled, of 
which two are fertile. (Fitzwilliam, common ). 
48. Parmelia conspersa (Ehrh.) Ach. Eight specimens, six fertile. 
Five are labelled “ conspersa four “ v. stenophy llaP one unlabelled. Five 
belong below, two of which are referable to the form as follows: 
49 . Parmelia conspersa isidiata (Anzi, ) Hue. 
50 . Parmelia conspersa stenophylla Ach. Three specimens, two 
ladelled thus, and one unlabelled. (All three forms are common in the Mo- 
nadnock region.) 
51. Parmelia centrifuga (L.) Ach. Six specimens, one fertile, four 
labelled. The fertile one is from “Monadnock,” another from “ C. C. 
Frost,” the shoemaker botanist of Vermont. One specimen first labelled 
“ P. conspersa? ” afterwards changed to “ P. incurva ” belong here. 
52 . Parmelia incurva (Pers.) Fr. One specimen, thus labelled. 
53 . Parmelia ambigua (Wulf.) Ach. Three specimens all thus labelled. 
(There is also a specimen in the Sprague Collection, Boston Society of 
Natural History, from Monadnock. These specimens labelled “ Parmelia 
ambigua albescens Wahl.” are evidently P. stellaris.).
