 new." 



The Journal of the Essex Co. Natural History Society, Vol. I, No. 2, 

 1839, at page 96, contains a notice of Cladonia uncialis, var. reticulata 

 (the C. Boryi of Tuckerman's Synopsis), by JOHN L. RUSSELL, with 

 notices of six other New England Lichens. The same plant is farther 

 noticed in No. 3 of the same Journal, at page 125, together with C. 

 gracilis, var. elongata. 



In the Proceedings of the Essex Institute are the following notices of 

 Lichens, all by Mr. Eussell : 



Vol. I, p. 15, mention of some lichens occurring in Brattleborough 

 and on Mansfield Mountain, Vt. Among them are Parmelia ostreata 

 Fr., Coniocybe furfuracea Ach., and C.pallida Fr., not previously no- 

 ticed as occurring in this country. 



Vol. I, p. 188, description of the new genus and its as yet solitary 

 species Hydrothyria venosa Russ., Verrucaria maura Wahl., Sphcerom- 

 phale atra Russ., and Verrucaria perpusilla Russ. These last two Mr. 

 R. now considers as doubtful. 



Vol. II, p. 35, mention is incidentally made of the occurrence of Par- 

 melia [Pannaria'] brunnea Sw., first found in this country by Mr. 

 Oakes. 



Vol. II, p. 134, Some Notes on the Cryptogamic Vegetation of the 

 Azores, contains notices of forty-five species- of Lichens, collected by 

 Thomas W. Higginson. 



The New American Cyclopaedia, Vol. X, contains a good general arti- 

 cle on Lichens, also by Mr. RUSSELL. 



A note in the American Naturalist for October, 1867, by the present 

 writer, mentions the occurrence of Biatora lucida Fr. in the White 

 Mountains (Berlin Falls). But Verrucaria margacea Wahl., is there 

 erroneously mentioned as having occurred to him in Vermont. 



The Annals of the Botanical Society of Canada, contain the follow- 

 ing notices of Lichens : 



Vol. I, p. 49, abstract of a paper entitled, What to Observe in Cana- 

 dian Lichens, by W. LAUDEII LINDSAY, read Feb. 15, 1851. 



Vol. I, p. 78, A List of Plants collected on the South and East Shores 

 of Lake Superior, and on the North Shore of Lake Huron in 1860, by 

 ROBERT BELL, mentions seven lichens, all common. 



Vol. I, p. 81, a paper on The Economical Uses of Sticta pulmonaria, 

 by N. T. DKUMMOND. 



A Provisional Catalogue of Canadian Cryptogams, by DAVID A. P. 

 WATT, published in Vol. II, No. 5, of The Canadian Naturalist, Octo- 

 ber, 1865, enumerates 156 species of Lichens, arranged after the Acha- 

 rian system, but without indication of stations or localities.
