Type: Poly poms fibrillosus Karst. 



Hymenophore annual, epixylous, sessile, dimidiate, simple or

I nonotiis fibrillosus Karst. Bidr. Finl. Nat. och Folk 37 : 72. 1882. 

 In 1876 Karsten considered this species synonymous with 



r 



Polypoms viilpinus Fr., but later said the two were very different. 

 According to Bresadola, Ochropoms lithnaiiicus Blonski (Hedwigia 

 281. 1889) is a true synonym oi P. fibrillosus. 



This species is rarely found in Asia, Europe and northern 

 North America on decaying logs of fir, spruce and other conifers. 

 Its bright colors make its discovery easy, while the fragile tubes 

 and rigid, friable context distinguish it readily from Pycnopoms 

 cinnabarinits,
