Garden within the past year were reported as the first to be 

 received from America. Through the kindness of Dr. Murrill 

 I have been able to compare my specimens with specimens of 

 European origin communicated by Bresadola, and the two are 

 identical. Mr. C. G. Lloyd of Cincinnati, Ohio, has reported the 

 species from different localities in this country. More recently 

 Long 2 has reported that a fungus identified as P. amorphus was 

 found rotting slash of the short-leaf pine in Arkansas. At the 

 writer's request specimens from the Arkansas collections were 

 sent for study. No evidence was found that the fungus is not 

 the species in question, but the sporophores are not well developed 

 and a positive determination of Mr. Long's specimens is im- 

 possible at this time. Hitherto it had appeared doubtful if the 

 species had so much of a southern range. Present indications are 

 that when well studied its range will be mostly confined to 

 southern Canada, New England, and the states bordering on the 

 Canadian line. 



In the vicinity of State College the species is not rare. Prob- 

 ably its small size and resemblance to related species have often 

 caused it to be overlooked or wrongly determined. In the 

 herbarium of the Pennsylvania State College there are at least 

 six different collections of the species and the writer's herbarium 

 contains half as many more. It is probably a safe statement 

 that at present as many collections are known from Pennsyl- 

 vania as from all other parts of the United States combined. 

 From this it might appear that the species can be of very little 

 economic importance as a producer of timber decay, but it must 

 be borne in mind that very few localities in the United States 

 have been thoroughly explored in a mycological way. Indeed, if 

 the prevalence of the fungus in the vicinity of State College can 

 be regarded as a criterion of its occurrence in other localities of 

 the same latitude it may even happen that the species is one of 

 the more common ones where different species of pines are 

 native. The fact that the fungus is not confined to the wood of 

 pitch pine adds interest in this connection. One collection has 

 been made from the wood of white pine (Pinus Strobus), one
