species of North American Fungi. 429 



with little radiating elevations, clothed with matted down, which in 

 the younger part appears velvety, in the older spongy. Gills mo- 

 derately distant, toothed, somewhat sinuated, rhubarb-coloured. 

 Very distinct from every form of L. abietina and L. scepiaria, 

 and approaching somewhat to L. cinnamomea, Fr., and still more 

 closely to L. subferruginea. Berk., but its bright colours are very 

 peculiar, which added to its grooved and corrugated surface and 

 somewhat sinuated toothed gills readily distinguish it. 



37. Boletus Curtisii, Berk. MSS. Pileo convexo viscosissimo 

 aureo-luteo ; stipite insequali exannulato cavo straraineo ; poris 

 subliberis demum fulvis. Curt. no. 3212. On the earth in pine 

 woods, South Carolina. 



Pileus 1 inch or more across, convex, subhemispherical, golden 

 yellow, clothed with a very viscid pellicle ; stem irregular, un- 

 equal, hollow, ringless, 2-3 inches high, i of an inch thick, pale 

 or straw-coloui'ed ; pores hollowed out at their junction with the 

 stem, nearly free, at length fulvous. Spores subelliptic, slightly 

 attenuated at either end, ferruginous yellow. 



A very beautiful and distinct species, as are several from the 

 southern United States. Some of these are now characterized, 

 but we are obliged to omit some very curious forms for want of 

 more perfect notes. 



38. Boletus Ravenelii, n. s. Pileo e convexo piano juniori 

 viscidulo, pulvere isete sulphureo (veli vestigiis) vestito ; came 

 albida ; stipite tenui velo flocculento pulveraceo sursum in an- 

 nulum fugacem contextum operto; poris flavis adnatis, tactis 

 virescentibus. Curt. no. 1970. B. sulphureus, Rav.MSS. no. 810. 

 In pine woods on the ground, July, South Carolina, H. W. 

 Ravenel, Esq. 



Solitary. Pileus 2 inches across, convex, at length plane, 

 somewhat viscid when young, covered with a bright yellow 

 powder the remains of the veil ; flesh whitish, unchanging, taste- 

 less. Stem 3 inches high, \-^ of an inch thick, solid; veil 

 arachnoid, covered with dust, which stains the stem as well as 

 the cap, forming a fugacious ring. Pores aduate, roundish and 

 angular, large, yellow, changing to greenish when bruised. 

 Spores ochraceous, elliptic, containing sometimes a single globose 

 nucleus. 



A most splendid species closely allied to B. hemichrysus, and, 

 like that, remarkable for the pulverulent veil. 



39. Boletus hemichrysus, n. s. Pileo nitide aureo rivuloso 

 floccoso pulvere flavo insperso ; stipite brevi e flavo-rufescente ; 

 tubis adnatis subdecurrentibus spadiceis. Curt. no. 2928. At- 

 tached to roots oi Pinus palustris, H. W. Ravenel, May, June. 



Pileus 6-8 inches across, convex, at length plane or irregu- 

 larly depressed, very bright golden-yellow, squamuloso-floccose.
