Petribowles containing sterilised gelatine and wrapped up in 

 double Sheets of sterilised filtering paper were not opened until their 

 arriv^al at the place of Observation; there the bowl was left open for 

 15 minutes and then carefuUy protected against further infections. In 

 this manner the author has tested the air from 78 places during 3 

 5''ears, and he gives a scheme of the specimens of fungi, found in 

 each sample; the greatest number of the species belong to the 

 Hyphomycetes, then come the Mucoraceae. A much larger number of 

 fungi is found in the open air, than in the air of rooms, most 

 likely for the reason that all places for the origin of germs are found 

 outdoors, and because the open air is in greater circulation and 

 whirls up the germs. Penicilliiim glauciim only is far more numerous 

 in the air of rooms. 



A new species: Citromyces tubijer is described (in Latin) and is 

 pictured with a rieh formation of small Sclerotia, of | mm. length.

Vestergren, T., Aeciditim Alaskaniim Trelease and Aecidium 

 Orchidearum Desm. (Svensk botanisk Tidskr. IL p. (6)— (8). April 

 1908.) 

 The author explains the morphologic difference between the 2 

 Aecidia, named in the heading, of which the former is found on 

 Hahernia {Piatanthera) spp., and Orchis aristata in North-America, 

 and which Holway considers as belonging to a Puccinia on Agrostis\ 

 the latter on Orchis spp., Listera, Hahernia and Epipactis inDenmark, 

 Schleswig-Holstein and France and belonging to Puccinia Orchi- 

 dearum- Phalaridis Kleb. 



The article is illustrated with 2 figures in the text.

As usual many very rare specimens are found among those 

 distributed. The greater part of the said 100 species are Uredineae 

 from foreign countries; but species of all the other groups of fungi 

 are also distributed. We postpone the discussion of the separate spe- 

 cies tili the instructive notes by which the distributed species are 

 usually accompanied, will appear in Botaniska Notiser.
