on specimens from France communicated by Bourdot, and they 

 are stated to be borne on the cystidia this in addition to the 

 usual incrustation of these cystidia. Since the resinous-colored 

 masses disappear in the liquids to which they are subjected in 

 sectioning and making aqueous preparations for microscopic 

 study, I am inclined to regard the presence of these masses as 

 perhaps due to weather conditions prevalent when the specimens 

 bearing them were collected a helpful, confirmatory specific 

 feature when present, but not a necessary morphological character 

 of P. guttulifera. Hence I have included under P. guttulifera, 

 specimens which have spores 7-10 X 3 4J^ y., lack gloeocystidia, 

 and have the aspect of P. pubera.

tuliferum, under the label Gloeocystis guttulifera.
