6. Ramalina pollinariella Nyl., Stevenville Crossing, sterile, on spruce. The 

 type of this species^ from "Terra Nova" Despreaux is preserved in the Museum 

 d'Histoire Naturelle, Paris, fide author. Hue, Arnold and Eckfeldt all record it, 

 and I find material in the latter' s herbarium. 



Arnold also records fastigiata Pers., fraxinea L., scopulorum Retz, subfarinacea 

 Nyl., cuspidata Ach., farinacea form tninutula Ach.., t hi- aus ta Ach., and intermedia 

 Nyl. The type of the last species' from "Terra Nova" is preserved in the Museum 

 d'Historie Naturelle, Paris fide author, and material representing it is in the Eck- 

 feldt herbarium, though besides those species above mentioned, none of the others 

 that Eckfeldt records are present, i.e., calicaris (L.) Fr., var. canaliculata Fr., rigida 

 (Pers.) Tuck., pusilla Prev., var. geniculata Tuck., polymorpha Ach., and pollinaria 

 Ach., Delamare records cuspidata Ach. 



Dactylina arctica (Hook.) Nyl., recorded by Eckfeldt under the synonym Cetra- 

 ria arctica Hook, is not represented in his herbarium. 



Thamnolia vermicularis (Sw.) Ach. Both Arnold and Eckfeldt record this 

 species, which is, however, not preserved in the latter' s herbarium. 



Coelocaulon aculeatwn (Schreb.) Link. Hue, Delamare, Arnold, and Eckfeldt 

 record this species under the synonyms Cetraria or Cornicularia aculeata (Schreb. ), 

 and the same authors its variety muricata Ach. The Eckfeldt and Paris herbaria 

 contain material of the species. 



Coelocaulon odentellum (Ach.) Howe. Eckfeldt records this species under the 

 synomym Cetraria odentella Ach., but no specimen is found in his herbarium. 



Coelocaulon divergens (Ach.) Howe. Hue, Arnold and Eckfeldt record this 

 species under the synonym Alectoria divergens (Ach.) Nyl., a portion of the mate- 

 rial no doubt is referable to Alectoria nitidula Th. Fr., as I found this species from 

 Newfoundland preserved at Paris. Arnold's records states "mit apothecien," 

 which is, I believe, the second record of the fertile state of this species. Eckfeldt' s 

 herbarium is now without material of this plant. 



Cetraria islandica (L.) Ach. Hue, Arnold, Delamare, and Eckfeldt record this 

 species and its variety crispa Ach. The variety is represented in the Eckfeldt 

 herbarium.* Cetraria hiascens Th. Fr. = C. islandicavar. Delisaei (Borr.) Schaer. 

 is also recorded by the above authorities, and Arnold also records the form 

 fastigiata Del. The distribution of C. islandica var. Delisaei (Borr.) Schaer. 

 No. 118 Lich. Bor.-Amer. and No. 187; Decade N. A. Lich., was collected by 

 Waghorne, Sept., 14, 1894 at Blanc Sablon. Arnold records Cetraria cucullata Bell, 

 under the synonym Platysma cucullatum (Bell.) Nyl., and Arnold and Eckfeldt 

 Cetraria nivalis (L.) Ach. the former under the synonym Platysma nivalis L. 

 Material of hiascens and nivalis are now in the Eckfeldt herbarium. Eckfeldt 

 alone records C. Richardsonii Hook., but the species is absent from his herbarium. 



7. Alectoria juhata (L.) Ach., Stevenville Crossing, on spruce, sterile. The 

 phase cana Ach. is suggested in part. The material is atypical, but represents the 

 species more nearly than any yet examined from North America. Delamare, 

 Arnold and Eckfeldt all record the species and it is represented in the latter's 

 herbarium. ,
