There are six species given as found in the United States B. cavipes 

 Kalchb., B. pictus Pk., B. paluster Pk., B. decipiens Pk., B. porosus 

 Pk., B. appendiculatus Pk. of these I have found and eaten four. B. 

 decipiens has, at this writing, not been seen by Professor Peck, but 

 Professor Farlow, of Harvard, has informed him of authentic specimens. 

 There is every probability of its being as edible as the others ; a descrip- 

 tion of it is, therefore, given. 



In consistency Boletinus is of the best, being rather like that of marsh- 

 mallows, and the same as Boletus subaureus. The flavor is mild and 

 pleasant. 



Professor Peck mentions that the smell of B. porosus is sometimes 

 unpleasant. I have been fortunate in not having had this experience. 



B. ca'vipes Kalchb. Pileus broadly convex, rather tough, flexible, 

 soft, subumbonate, fibrillose-scaly, tawny-brown, sometimes tinged with 

 reddish or purplish. Flesh yellowish. Tubes slightly decurrent, at first 

 pale-yellow, then darker and tinged with green, becoming dingy-ochra- 

 ceous with age. Stem equal or slightly tapering upward, somewhat 

 fibrillose or floccose, slightly ringed, hollow, tawny-brown or yellowish- 

 brown, yellowish at the top and marked by the decurrent dissepiments 

 of the tubes, white within. Veil whitish, partly adhering to the margin 

 of the pileus, soon disappearing. Spores 8-iox4/x,. 



Pileus 1-5-4 in- broad. Stem 1.5-3 in. lon g 3-6 lines thick. 

 Swamps and damp mossy ground under or near tamarack trees. New 

 York, Peck; New England, Frost. 



The pileus is clothed with a fibrillose tomentum which becomes more 

 or less united into floccose tufts or scales. The umbo is not always 

 present and is generally small. The young stem may sometimes be 

 stuffed, but, if so, it soon becomes hollow, though the cavity is irregu- 

 lar. The freshly shed spores have a greenish-yellow or olivaceous hue, 

 but in time they assume a pale or yellowish-ochraceous hue. This spe- 

 cies is apparently northern in its range. It loves cold sphagnous 

 swamps in mountainous regions. Peck, Boleti of the U. S.
