520 MuRRiLL : The Boleti of the Frost herbarium 



punctate, but often reticulate at the top or for some distance 

 downward. 



Boletus flavidus Fries. 



Most of the specimens appearing under this name in the Frost 

 collection belong to what we know in this country as B. aniericanus 

 Peck. They were collected in pine woods and grassy places, and 

 are mostly very poorly preserved. Twenty specimens are glued 

 to sheets and five are contained in a small paper box. A larger 

 box similarly labeled contains seven good specimens of B. liiteiis. 

 Boletus flavus With. 



Represented by about fifteen moulded specimens in a paper box, 

 which may doubtless be referred to B. liiteiis. 



Boletus Frostii Russell. 



Represented by six sheets, containing in all twenty-one good 

 plants and seven in fair condition. Where the habitat is mentioned, 

 it is "borders of woods." The name is written " ^. Frosti" or 

 " B. FrosHi" indifferently. The species is not distinct from v5. 

 alveolatJis. 



Boletus granulatus L. 



Two sheets, contaitiing ten specimens in a fair state of preser- 

 vation, represent this common species. 



Boletus griseus Frost. 



Represented by three sheets containing thirteen good speci- 

 mens. The species was published by Peck in the 29th Report 

 of the N. Y. State Museum of Natural History. Dried specimens 

 may be easily confused with B. ornatipes, but the white color of 

 the tubes readily distinguishes it in the field. Frost's notes refer 

 to B. griseus with intensely yellow tubes, which was evidently B. 

 ornatipes. 



Boletus innlxus Frost. 



Represented by a sheet containing three good plants collected 

 in grassy woods in 1866 ; also a sheet containing two small poorly 

 preserved specimens united at the base. B. iiinixus is plainly an 

 abnormal or distorted form of B. auriponis, representing the max- 

 imum of size and irregularity in the tubes and a reclining habit not 

 usual in typical plants. The descriptions are practically identical, 

 and the type specimens of B. innixtis'show the characteristic yellow
