An enumeration of 118 species with hosts, localities and many 

 valuable critical notes and description of 2 new species; Chrysomyxa 

 Rmnischiae in foliis vivis Pirolae secundae and Uromyces ßectens 

 [Microurontyces) in foliis vivis Trifolii repentis. Of the more notable 

 species found, viz: Melanotaenium cingens (Beck) P. Magn., Phrag- 

 midium tiiherciilatinn Müll., Pncc. Campaniilae Carm. , Piicc. Pruni 

 sphiosae Pers. st. I. Of Anenione ranunculoides, Pucc. Sonchi Bob., 

 Uredinopsis filicina (Niessl) P. Magn. and Uromyces Trifolii repentis 

 (Gast.) Liro detailed records are given and many literar}- references 

 added. I. Lind (Gopenhagen).

The results of the author's experiments are the following: 

 Melmnpsora betulina (Pers) Desm. forms no Aecidium on Larix in 

 the northern countries, and the fungus can not hibernate as uredo- 

 spores or as mycelium in the leaves on the ground, but only (pos- 

 sibly as mycelium) in the leaves, which remain on the young 

 Betula--p\2iXs.\& through the winter and in the buds of the youngest 

 plants, but never in the older trees; the Melampsora is for this reason 

 compelled to commence every year on the young plants and to 

 ascend graduall}' to the higher placed leaves. 



Chrysomyxa Ledi (A, & S.) deBy. is identic with Chrysomyxa Wo- 

 ronini Tranz. and Chrysomyxa ledicola (Peck) Farlow and belongs 

 as well to Aecidium, abietinum Alb. & S. as to Aecidium coruscans 

 (Fries) Reess. Peridermium Pini (Willd.) Kleb, can exist up to 20 

 years in the same branch or stem of Pinus silvestris; the author has 

 sawn more than 1000 trees across for studying the effect of the fun- 

 gus. Peridermium Pini as well as Chrysomyxa Abietis Udg. attack 

 often a Single tree in a high degree, leaving the surrounding trees 

 of the same species unattacked. The reason for this must be some 

 inheritable predisposition of the host. 



Peridermium too is often attacked by Tuberculina maxima Rostrup. 



Aecidiospores of Puccinia Violae (Schum.) de Gand. taken from 

 Viola canina, were placed on Viola tvicolor and caused in all 12 

 cases the development of Uredo on it. Puccinia Violae is consequently 

 identical with Puccinia depouperans (Vize) Syd.

In the same manner, as Dr. Liro, (Lindroth) formerly has given 

 a monography of the Finnish species of Ramularia, he has in this 

 work put a great labour in compiling materials for a monography 

 of all species of Uredineae of F Inland. He deals not only with the 

 246 species, which hitherto have been found, but he also gives a 

 description of the species, which possiblj^ could be found yet. The 

 author has a quite new method in nominating the Uredineae; in all
