be Byjus feptka of Linnoeus. Dr. Withering traces it, 

 in his opinion, to fig. 3. of this plate. We, however, 

 have no aflurance of the latter having been deteiled 

 with pores, or other frudification, like this white one, 

 ■which has been found in great abundance, and was 

 brought me from Oxford by my good friend Dr. Wil- 

 liams. Its fibres are eafily decompofed. The figure 

 reprefents it in fome degree compreffed. 



Fig. 7. Boletus versicolor? 



THIS is a Poria of fome authors, and is not uncom- 

 mon under wooden window-fills or copings over the 

 little brick, walls in hot-houfes, extending to a foot or 

 more in length. I do not know that it has been found 

 with a pileus. The pores refemble thofe of 5 verfi- 

 color, being moftly round and white, fometimes length- 

 ened out. The fubliance is nearly the fame, being 

 white cottony fibres clofely comprefTed. B. verficolor 

 is occafionally very fportive, and deflitute of a pileus. 



Fig. 8. Boletus Fibula. 

 I WAS favoured with fpecimeris of this Boletus by 

 D. E. Davey, Efq. of the Grove, Yoxford, in Suffolk. 

 They grew on his wine-cellar door. The button-like 

 form, with an umbilical root, like a fhank, gives this 

 fpecies a remarkable appearance. The pores in the 

 centre are irregular, fmall, and fhallow ; the fubftance 

 fome what cottony, and clofer than the dry rot. Boletus 

 lacrymans. I cannot help mentioning here a large flat 

 fpecimen of Boletus lacrymans, kindly communicated 

 to me by the Earl of Dartmouth, about nine inches in 

 diameter, the pores irregular in the outward circle, 

 the centre compofed of fmall, irregular, fomewhat bo- 

 troid protuberances. 



Fig. 9. Boletus latus. 

 THIS may be often found fpreading, in irregular 

 patches, on bits of flick, &;c. in damp places. The 

 pores, when any, are fomewhat central. The fubflance 

 rather refembles fig. i . of this plate, but is more com- 

 prefTed.
