176 STUDIES OF A.WERICAN FUNGI. 



ulate, usually to the base, but sometimes only toward the apex. It 

 is usually more strongly reticulate over the upper half. The stem is 

 erect or ascending. 



The plant grows in woods, in leaf mould or in grassy places. It 

 is usually single, that is, so far as my observations have gone at 

 Blowing Rock. Berkeley and Curtis report it as cespitose. I have 

 never seen it cespitose, never more than two specimens growing near 

 each other. 



Boletus ornatipes Pk., does not seem to be essentially different from 

 B. retipes. Peck says (Boleti U.S., p. 126) that " the tufted mode 

 of growth, the pulverulent pileus and paler spores separate this spe- 

 cies" (retipes) "from the preceding one " (ornatipes). Inasmuch as 1 

 have never found B. retipes tufted, and the fact that the pileus is not 

 always pulverulent (the majority of specimens I collected were not), 

 and since the tint of the spores varies as it does in some other species, 

 the evidence is strong that the two names represent two different hab- 

 its of the same species. The tufted habit of the plants collected by 

 Curtis, or at least described by Berkeley, would seem to be a rather 

 unusual condition for this species, and this would account for the 

 smaller size given to the plants in the original description, where the 

 pileus does not exceed 5 cm. in diameter, and the stem is only 5 cm. 

 long, and 6-12 mm. in thickness. Plants which normally occur 

 singly do on some occasions occur tufted, and then the habit as well 

 as the size of the plant is often changed. 



A good illustration of this 1 found in the case of Boletus edulis 

 during my stay in the North Carolina mountains. The plant usually 

 occurs singly and more or less scattered. 1 found one case where 

 there were 6-8 plants in a tuft, the caps were smaller and the stems 

 in this case considerably longer than in normal specimens. A plant 

 which agrees with the North Carolina specimens 1 have collected at 

 Ithaca, and so I judge that B. retipes occurs in New York. 



Boletus chromapes Frost. — This is a pretty boletus, and has been 

 reported from New England and from New York State. During the 

 summer of 1899 it was quite common in the Blue Ridge mountains, 

 North Carolina. The plant grows on the ground in woods. It is 

 6-10 cm. high, the cap 5-10 cm. in diameter, and the stem is 8-12 

 mm. in thickness. It is known by the yellowish stem covered with 

 reddish glandular dots. 



The pileus is convex to nearly expanded, pale red, rose pink to 

 vinaceous pink in color, and sometimes slightly tomentose. The 

 flesh is white, and does not change when cut or bruised. The tube 

 surface is convex, and the tubes are attached slightly to the stem.
