This would seem to explain the reference, in the original descrip- 

 tion, to the scarlet mouths of the angular tubes, which certainly 

 does not otherwise apply to our plant. 



Boletus Ravenelii B. & G, another member of the Pulverulenti, 

 was rather more common than the preceding species and almost 

 as striking. It was frequently found with its large fluffy veil in- 

 tact, and thickly covered with its sepia-brown spores. Its slender 

 flexuous stipe was a marked characteristic of the form at Brook- 

 side. 



Boletus cyancscciis Bull, has been considered a northern species, 

 but it was not rare along the mountain roads. The first speci- 

 men observed was just emerging from the bare soil on the road- 

 side. Its yellow tomentum was so characteristic and its appear- 

 ance so distinct that it was visited daily as it slowly developed, 

 though with no suspicion of its identity. It was afterward found 

 fairly abundant, but always in the clay-banks, along the roads, 

 with which its grayish yellow color harmonized perfectly. 



Among the rosy spored species Boletus alutarius Fr. and Bole- 

 tus nigrellus Pk. were the most interesting, and Boletus gracilis 

 Pk. the most abundant. 



Boletus nigrellus Pk. was observed in all its stages and differed 

 so widely from the original description, that it seemed at first 

 distinct. It was at first "blackish" in color, but soon changed 

 to a sordid gray. Its flesh, however, was decidedly not " white 

 and unchangeable," as the entire plant, when handled or bruised, 

 blackened rapidly, the dried specimens being inky black. Pro- 

 fessor Peck, who has examined my specimens, pronounces them 

 identical with his species, so that it is evident that the original 

 description must be modified. 



Boletus alutarius Fr. grew all summer in turf beneath the same 

 chestnut tree, where it was kept under observation. It is an at- 

 tractive plant, unlike any of its relatives. In its earlier stages it 

 has a distinct pubescence, but it becomes quite smooth with age. 



Peck's two fine species, Boletus separans and Boletus eximius, 

 were generally distributed on the hillsides, but neither was com- 

 mon. Boletus eximius Pk. fell far below the huge dimensions of 

 this species as we have found it in Maine.
