 (By A. Lorrain Smith.) 



Relation between G-onidia and HyphaB in Lichens.* — U. N. Danilov 

 gives a resume" in German of his paper (Russian) on Lichen-gonidia. 

 He studied species of Evernia, Parmelia, Xanthoria, Ramalina, Usnea, 

 Cladonia, and Lecanora, all of them common examples of heteromerous 

 lichens, and in all of which he found evidence of the antagonistic cha-
