LICHENS OF NEWFOUNDLAND 155 



The I'Abbe Hue records also dasypoga Ach., and plicnta Fr. The P^ckfeldt her- 

 barium does not contain either of these plants from Newfoundland, though both 

 were recorded in his list. 



2. Usneajlorida (L.) Web., Stevenville Crossing, sterile (form hirla) on spruce. 

 Delamare records barbala L., which he considers a synonym oi flarida. Arnold 

 recorded florida and form glabrata Ach., and Eckfeldt Jlorida Fr., but the only 

 plant of this stock from the island in his herbarium I refer to U. cornutaFlot., Dr. 

 Zahlbruckner calling it U. Steineri Zahlbr., a closely allied species (series Lep- 

 tinae). The status of U. cornuta Dr. Zahlbruckner believes doubtful, and though 

 Koerber included Flotow's cornuta in his synonymy. Dr. Zahlbruckner considers 

 them separable. U. cornuta Flot. has been attributed to British America by 

 Stirton^ and the plant represents an inflated condition of florida suggesting U. 

 arliculata. 



3. Usnealongissima Ach.., Bottom brook — ^sterile, on spruce. Represents phase 

 tenuis Th. Fr., as do all our eastern North American specimens. 



Arnold records longissima as does also Eckfeldt, but the latter's specimen rep- 

 resents a corticate and atypical condition, noted before from Barclay Sound, B. C.'' 

 which I have described as a variety, though Dr. Zahlbruckner considers it a variety 

 of U. calif ornica Herre. It represents the Pachynae group, however, to which long- 

 issj77ia belongs and not the Mesinac group which should include californica, a 

 phase of U. -plicata fL.) Web., as already indicated in my former paper. The plant 

 is U. longissima var. corticata Howe.^ 



The I'Abbe Hue also records U. intestiniformis Nyl. The specimen on which 

 his record was based he advises me is impossible now to locate. The only other 

 species recorded by Eckfeldt, represented by a specimen in his herbarium, is U. 

 trichodea, the example so labelled, proving, however, to be Alectoria sarmento^a 

 Ach. The others he records are var. ceratina Schaer., var. hirta Fr., form strigosa 

 Ach., iorm glabrescens 'Nyl., and cavernosa Tuck. Arnold and Delamare record also 

 U. microcarpa Arn., which I have found to be a synonym of U. cavernosa Tuck. 



Eckfeldt records Evernia prunastri (L.) Ach., which for eastern plants = Letha- 

 ria thamnodes (Flot.) Hue. No specimen of either plant is to be found in his 

 herbarium. 



4. Ramalina farinacea (L.) Ach., Stevenville Crossing, on spruce, sterile. Part 

 of the material represents the phase pendula Ach. or gracilenta Ach. Delamare, 

 Arnold and Eckfeldt all record this species, and material comparable with mine is 

 preserved in the latter's herbarium. 



5. Ramalina dilacerata (Hoffm.) Wain., Stevenville Crossing, on spruce, fertile. 

 Delamare, Arnold and Eckfeldt all record this species under the synonym minus- 

 cula Nyl., but no specimens are in the Eckfeldt herbarium, though No. 207, Lich. 

 Bor.-Amer. Cummings, etc. and No. 277, Decades N. A. Lich. Cummings, etc., 

 were collected by A. C. Waghorne, April 3, 1897 at Middle Arm, Newfoundland.

 received since this paper was written states "Darin haben sie recht, dass Usnea 

 Calif ornicanichi zu des Pachynae gehort."
