(Tab. I. Fig. 25—28.) 



In harvest, this fungus is observed on the rind of birch 

 trees in moist places. It is scarcely a line in size, and of a 

 brownish-yellow colour. On a short stalk stands the pear or 

 flask shaped peridium, contracted below the mouth. The 

 mouth is covered by a whitish round operculum, which opens 

 and shews the spora?, with intermingled tufts of hairs as the 

 contents of the peridium.
