The stipe is more often as described by Frost, but specimens 
may be found which are “attenuateddownward.'’ This brings the two 
plants into close coincidence and renders it nearly certain that our 
common plant is B. Betula. This conclusion is more probable when 
we remember that the rough shaggy stipe was made the important 
character in the original description and that Schweinitz found his 
plant common in both North Carolina and Pennsylvania. 
Mr. Lloyd has observed Boletus Morgani in all its stages and 
considers that it is a state of B. Betula rather than a distinct species.* 
This would reduce our three species of shaggy stiped Boleti to one and 
unite them under the oldest and best name. 
* During a collecting season several years ago I had opportunity to study “Boletus Morgani ” 
When Prof. Peck described Boletus Russelli and Boletus Morgani he apparently did not know of 
Schwemitz's specie-, hater in his monograph on the Boleti he distinguished B. Morgani from B 
Betula, by the bright red alae of the stem. The distinction is of no value. When the plant 
is m its prime the alae are bright colored but they fade out as the plant gets older and assume the 
uniform dull yellow ascribed to them by Schweinitz.—hloyd.
