Lichens. 



Contribution to the Lichen Flora of the West Coast. — A. H, 

 Magnusson {Svensl Bot. Tidsk., 1919, 13, 75-92). The author 

 sketches work previously done in collecting lichens in the district of 

 Sweden selected by him for examination. He then gives a list of the 

 lichens found by him, with habitat and locality. A. L. S. 



Concerning the Species of Brown ParmelisB and Hypogymise^ 

 their Occurrence and Fertility, especially on the West Coast. — 

 A. H. Magnusson {Svensk Bot. Tidsk., 1916, 10, 365-73). The 

 author gives a descriptive list of these lichens. The notes are full and 

 instructive. A. L. S. 



Mycetozoa. 



Notes on Species of Myxomycetes. — Ch. Meylan (Bidl Soc. VaiuL 

 ScL Nat., 1919, 52, 447-50). Abundant growths of the species Trichia 

 botrytis, T. lateritia and T. suhfusca induced Meylan to make a com- 

 parative study of their specific characters. He finds that they differ in 

 habitat, in the form of the elaters, and in the plasmodium. He found 

 also, on the bark of Picea excelsa, a new species, which he names 

 Lamproderma Gulielmse, distinguished from neighbouring species by the 

 minute size of the stalk and sporangia, and by larger spores. Meylan 

 further describes two new forms of Didermse, A. L. S.
