Mycological Flora of the Rockies 117 



description does not take into account the longer teeth of ElHs' 

 specimens. Our smaller specimens, although possessing mature 

 spores, are evidently not full size and are well indicated by 

 Coker's illustrations of the species. (Jour. EUsha Mitchell Sci. 

 Soc, 34: Plate 7, facing p. 172. 1919.) 



Odontia setigera Fr. Sept. Infrequent. Tolland. On 

 coniferous wood. 



Phlebia albida Fr. Sept. Rare. Tolland. On log of Abies 

 lasiocarpa. 



Boletaceae 



Boletus americanus Pk. Under spruce and pine. Tolland. 



Boletus punctipes Pk. 



Under spruce and pine. Tolland. This species which some 

 have included with B. granulatus Fr., was very abundant and 

 is entirely the Peck conception. Only in age or when dried, 

 does it show the characteristics of its sister species. Typical 

 B. granulatus was not seen. 



Boletus scaber Fr. Under spruce and pine. 



Boletus tomentosus sp. nov. 



Pilcus 5-8 cm. broad, convex-subexpanded, obtuse, dry, be- 

 coming sub viscid in wet weather, ground color "antimony yel- 

 low" (Ridg.), covered with "yellow-ochre" to "buckthorn 

 brown" tovientose, rather small scales, which are disposed in an 

 areolate manner; flesh white, changing slowly to "pale sky-blue" 

 (Ridg.), amber-yellow under the cuticle. Tubes depressed 

 around stem, almost free, convex, 4-6 mm. long, 1-2 to a mm., 

 angular, radiately subelongate, "yellow-ochre" at first, soon 

 changing to "tawny-olive" or "buckthorn-brown," dissepi- 

 ments thick; mouths concolor, uneven. Stem 3-5 cm. long, 

 1.5-2 cm. thick, soHd soon cavernous or grubby, subcompressed, 

 even, obscurely subtomentose, "amber-yellow," dotted by scat- 

 tered, minute, reddish-brown points; flesh white changing to pale 

 sky-blue. Spores narrowly subfusiform, 8-9 x 3 /x, subhyaline 

 or scarcely tinged straw color. Taste mild. Odor slight. 



Under fir and pine. Leal and Tolland, Colorado, Aug.-Sept. 



This is doubtless the plant referred to B. hirtellus Pk. by 

 Overholts. If it is that species, the descriptions of it so far pub-
