Caeoma. 

 Gaeoma abietis-pectinatae IJeess.^ The aecidiospores may 

 be found on the lower surface of young 

 needles of silver fir ; the aecidia are yellow 

 elongated cushions situated on either side 

 of the needle mid-rib, and are without 

 peridia. Pycnidia (sperniogonia) are pro- 

 duced before the aecidia. The mycelium is 

 septate and intercellular with few haustoria. 

 I have found the fungus fairly abundant 

 on the Alps and in the Danube valley near 

 Passau. Teleutospores are unknown.
