Lichens. 



Lecanora subfusca.*— A. Hue has looked through a large amount of 

 material, and finds that this very wide-spread Lichen has three distinct 

 varieties and a number of forms. They are distinguished by the form 

 of the apothecium. 



Lichens from Socotra.f — J. Steiner worked through a small collec- 

 tions of Lichens made by O. Simony, and found three new genera and 

 eleven new species. The new genera are Simonyella and Roccellographa, 

 both belonging to the Koccellacese. The latter has a distinct Graphidean 

 fruit, and this confirms Darbishire's view of the position of Roccella 

 among the Graphideae. The remaining new genus, Phlc&opeccania, 

 belongs to the family of Glceolichenen. 



Mycetozoa. 



Development of Myxomycetes. J — M. Pinoy had already found that 

 various species of endosporous myxomycetes would not grow in pure 

 cultures until some bacterium was added to the medium. He has carried 

 out further researches on Dictyostelium mucoroides. He considers that 

 the bacterium associated with the species of Acrasise exercises a consider- 

 able influence in determining the colour and the form of the organism, 

 and that species described as distinct from each other are merely the same 

 species associated with different chromogenic bacteria. 



Fries, Rob. E. — Myxomyceten von Argentinien and Bolivia.
