Lichens. 



(By A. Lorrain Smith, F.L.S.) 



American Lichens.*— Bruce Fink publishes his last paper on 

 Cladonia, giving an account of several species with red fruits, G. digitata, 

 C. deformis, and G. bellidiflora. The first of these grows usually on 

 trunks or on decaying wood in forests, the two latter on soil : G. deformis 

 in woods, G. bellidiflora on high open places ; detailed descriptions are 

 given of each. A. S. Foster f describes the lichens that are to be found 

 growing on Alnus Oregana, a tree that occupies any area that has been 

 burned over ; it is a favourite habitat and a large number are recorded. 

 R. Heber Howe, jun.,1 has been examining the lichens of the Monadnock 

 region that had been collected by G-. A. Wheelock. He publishes a first 

 list of 27 species of Ramali/ia, Getraria, Usnea, and A lector ia. with some 

 few notes appended.
