POLYPOREI 207 



under surface 'vs flat will yield a most beautiful spore 

 print if laid upon white paper and protected from the 

 atmosphere, as described in a later chapter. 



A reproduction of one of these prints is shown in 

 Plate 38, the white reticulation representing the con- 

 tact of the tube orifices with the paper, 

 Black each tube depositing its dot composed 

 spore=prints of spores, the depth of color increasing 

 in proportion to the time involved in 

 the deposit. A single mushroom will yield a half- 

 dozen or more prints. This fungus dries readily, 

 and may be kept indefinitely. 



SUSPICIOUS BOLETI 

 Boletus felleus — B. alveolatus 



In Plate 24 are shown two examples of the Boleti 

 which have commonly been accounted poisonous — 

 B. felleus and B. alveolatus — and, in the absence of 

 absolutely satisfactory assurance to the contrary, it is 

 safer from our present point of view to consider them 



still as suspicious and to give them a 



Maligned wide berth. There can be no doubt 



species but that the popular condemnation of 



the Boleti has been altogether too 

 sweeping. The gradual accession of many question- 

 able species to the edible list of Messrs. Mcllvaine 

 and Palmer and other daring mycophagists is a 

 sufficient attestation of this fact. Thus subtomento- 

 sus and cyanescens, already described, always hereto- 

 fore branded as reprobates, are now redeemed from 

 obloquy, and even the universal ill- repute of the B. 

 satanas, with its pale pileus and blood -red pores,
