kind of preparation seems to destroy the bitter taste. But in one 

 instance which was brought to my notice, sickness and vomiting 

 followed the eating of the Sensitive boletus, Boletus sensibilis, a 

 species which assumes blue colors in a remarkable degree where 

 bruised or broken. All the family partaking of it were made 

 sick, but all recovered. 



In the genus Polyporus, the stratum of ]3ores is not separable 

 from the cap. Most of the species grow on wood, and are too 

 tough to be of any use as food. A few grow on the ground, but 

 even these are inclined to be tough, and though the species are 

 numerous, very few are iit to be classed as edible, and these are 

 not very good except when young and tender. A single example 

 will be given. 



The Sulphury polyporus, Polyporus sulphureus, is so named 

 because of the bright sulphur yellow color of its stratum of pores. 

 The caps have no well developed stems. They are side growers, 



and are attached to their place 

 of growth by one side or a 

 part of the margin of the cap. 

 They commonly grow in large 

 clusters, one above another^ 

 and side by side, and variously 

 grown together where they 

 come in contact with each 

 other. AVhen fresh, the up- 

 per surface of the caps, which 

 is more or less irregular and 

 uneven, is of a j^ale reddish or orange color, often tinged with 

 yellow and easily fading with age or in drying. The pores are 

 rather short and so small as to be easily overlooked, but their 

 beautiful clear pale yellow color is much more durable than the 

 color of the upper surface of the cap. The caps are commonly 

 four to six inches broad, and about half an inch thick. 



They grow on dead wood of various kinds of trees, and the 

 species has a wide range. The showy clusters are often seen 

 growing from dead spots in the trunks or branches of living trees. 

 Even the fruit trees of our gardens and orchards are sometimes 

 attacked by it. It occurs during summer. 



Only young and tender caps should be used for food. Just 

 before or about the time the pores begin to develop, the caps are 

 in the best condition for eating. 



In the genus Fistulina, the under surface of the cap is covered 

 with minute hollow tubes, which stand verticallv and closelv side 



Boletus oastaneu!~. Polyporus sulphureus.
