Bulletin 6 



found by Mr. A. H. Norton in the white cedar swamp of 

 Alfred. So far as I am aware, this is the first record for 

 Maine. Cetraria pinastri (Scop.) Fr., I have collected or 

 examined from seven of the sixteen counties of Maine, but 

 the closely allied C. juniperina has thus far eluded me. Mr. 

 Norton also sends to me from the Alfred swamp, gathered 

 from cedar twigs, Alectoria chalybeiformis , forma nidulifera 

 (Norrl.) Merl., in a perfectly characterized condition. This 

 plant was first identified by the writer in American material 

 about fifteen years since, and occasionally turns up from the 

 northern United States and the Canadas. I do not know of a 

 published record for the United States. 



The writer found himself unable to attend either the 

 Moosehead Lake or Kingfield meetings, but Mr. A. H. Norton 

 on the latter occasion visited Mt. Bigelow, Dead River, and 

 collected lichens on its summit and flanks. On the summit 

 was found Cetraria cucullata (Bell.) Mudd, Cetraria Islandica 

 in a fruited state, and Cetraria Islandica crispa Ach., in con- 

 siderable abundance, with a portion of the specimens sparsely 

 fruited. C. cucullata is an arctic and alpine plant, and 

 hardly to be expected on a mountain of the moderate altitude 

 of Mt. Bigelow. No portion of the material contained even 

 fragments of Cetraria nivalis, invariably associated with C. 

 cucullata on the New Hampshire mountains and on Mt. 

 Katahdin, and no scrap of Thamnolia vermicularis , another 

 associate, was found. While various writers, including 

 Tuckerman, have ascribed C. cucullata to sub-alpine stations, 

 the species is essentially Hudsonian in its zone relations. 

 Cetraria Islandica crispa is another alpine and arctic plant of 

 common occurrence within its zone limits, and in the speci- 

 mens submitted by Mr. Norton presented that phase of devel- 

 opment in which the laciniae are more or less erect rather 

 than appressed and divergent. The plants were colored much 

 as in the species, the laciniae narrowed upwards, the margins 

 definitely incurved, setulose-spinulose, and with summits 

 alone brown. The plants agree best with Scandinavian and 

 Finnish examples in my herbarium. Later in the autumn of 

 1919 Mr. Norton visited Speckled Mountain, in Grafton, 

 Oxford County, and found exactly similar associations of C. 

 cuaillata and C. Islandica crispa on its summit.
