Soil-sample No. 7. 



Heath; by the spring of Unartuarsuk. July 8, 1916. 



Actinomijces roseus Kr. and AspergiUus jiimigatus Fres. 



The AspergiUus was a little different from the common A. fumigatiis, 

 the heads of conidias being smaller than in the common form. The usu- 

 ally described A. jumigatiis has conidias being 2 — ?> /.i in diameter; the 

 conidias of my form are 2 — 2.5// in diameter. The conidial heads of the 

 common form are 30 — 40// in diameter; of my form 20 — 30// in dia- 

 meter. In botli these caracters my form thus differs from the originally 

 AspergiUus fumigatus. As the fungus in question does not differ in other 

 points I nevertheless refer it to A. fumigatus. It must be remem- 

 bered that the dimensions of fungi often are very varying according 

 to the culture methods employed. I don't fmd it justified to describe 

 a new species upon these differencies.
