Obsebvations — This species has been a puzzle to us. It is very 

 close to H. flavescens; in fact it differs in color from that species in 

 much the same way that H. cuspidatus differs from H. acutoconicus. 

 H. marchii was reported by Moller ( 1945 ) from the Faeroes, but he 

 did not describe the pileus as viscid, and we are inclined to question 

 his identification on that basis. His species, by virtue of the non-viscid 

 pileus and somewhat curved-apiculate spores, may possibly be the 

 same as H. quietus Kiihner. Perhaps H. marchii should be regarded as 

 a variety of H. puniceus, but this is not the impression one gets from 

 seeing both in the fresh condition. H. puniceus has a characteristic 

 appearance. It seems to be a fleshier species than H. marchii. It differs 

 from H. laetissimus in its much more slender stipe (3-6 mm thick), in 

 its fading pileus, and orange-yellow to pale yellow lamellae. On the 

 other hand, in H. laetissimus the stipe is 10-30 mm thick, the pileus 

 scarcely fades, and the lamellae are peach red. 



Favre ( 1955 ) records this species from Switzerland, and Hongo 

 (1951c) reports it from Japan (a first report). Morten Lange (1955) 

 has found it in Iceland, and Lundell (1932) reports it from Sweden.
