BOLETUS coriaceus tenuis, dimidiatus. fupra lanatus zonatus CCXI", 

 nee variegatus, tubis d<zdaleis fubrutilo cinereis._ Bulliard malar, 

 texte, P. 365. No. 43. 



ONE-COLOURED BOLETUS. 



TAB. CLXIII. 



*T"*HIS is mod: generally halved, and adhering by one fide ; but 

 ■*• fometimes the bafe is lengthened out into a kind of fpurious 

 footftalk, as is reprefented in one of the lower figures on the 

 plate. The upper furface is covered with a clofe pile, or hairy 

 nap, of a brownifh buff-colour, and marked with zones or cir- 

 cles of the fame colour, a little darker. The margin is acute, 

 varioufly waved and lobed, and the plants fometimes lie over one 

 another in imbricated order. 



The internal fubftance is thin, white, tough, and leathery. 



The lower furface is plain, or very little convex, while young 

 cream-coloured, changing with age to a brownifh afh colour. 



The tubes are very fhort, adhering together by their fides, and 

 infeparable from the flelh of the pileus. The pores are very fmall 

 and of various figures ; thofe towards the bafe, in the fpecimen 

 before me, are larger, oblong, or angular, thofe near the margin 

 are round and very minute. 



This is the plant which I have formerly fuppofed to be the 

 female or feeding fpecimen of my Boletus auriformis. But as 

 the two are placed in different genera by Monfieur Bulliard, I 

 do not at prefent infill: upon it, I drop this hint, that the fuppo- 

 fition may be confirmed or confuted by the obfervations of others.
