was very rich both in species and varieties, the foliaceous lichens 

 becoming; rarer and the crnstaceous forms more frequent. Alto- 

 gether from the heights of these mountains he gathered 112 species 

 and 70 subspecies or varieties. On the Little Saint Bernard he 

 found 70 species and 17 subspecies or varieties. Lichens, he found, 

 were not susceptible to extreme cold, and a thick coating of snow due 

 to an avalanche did not seem to change them. On the heights 

 the colour was slightly fainter, but all were fertile and the apothecia 

 normal and sporiferous ; the thallus was reduced, but not altered anato- 

 mically. 



Tarbellien Lichens.* — Hue has thus named his list of lichens col- 

 lected in the country to the west of the Landes and the Basses-Pyrenees. 

 He gives an historical sketch of lichens as regards this district, and 

 describes the district through which he himself worked, in the neigh- 

 bourhood of Dax. He found much the same lichen flora there as 

 further north on the English Channel, both regions being under the 

 influence of the Gulf Stream. He lists 51 species, among others 

 Phseographis Lyellii, a rare species first found in the New Forest, 

 England, in 1808, and published by Smith in Sowerby's English 

 Botany as Opegrapha Lyellii. He gives copious notes on many of the 

 species, and adds an index. 



American Lichens.f — G-. K. Merrill has placed some badly defined 

 forms of Gladonia under G. multiformis. It is nearly allied to 0. cris- 

 pata and G. furcata ; unlike the latter it bears cups, and it differs from 

 G. crispata in having fissured podetia and usually closed cups. Merrill 

 also describes Alectoria tortuosa sp. n., a pendulous greenish-yellow species 

 from British Columbia. 



T. C. Frye % gives a list of lichens collected in the Mount Hood 

 region, Oregon. He found Evernia vulpina — usually a sterile form — 

 fruiting at high altitudes.
