burn, under oak-trees in the middle of O<5lober. The tubules 

 were covered for the whole length with the fructifications, in 

 the form of a yellow powder. The exterior coat or film over 

 their mouths was rotted off and periflied, which fhewed them to 

 great advantage. 



The tubules of thefe are capable of being feparated from the 

 crown, or the upper flefhy part. 



24. YelloiviJJj-ivhite Mufljrome -with quadrangular tubules, and a thick 

 pedicle (m). Under the fir-trees on the hill by the Roman wall at 

 Tower-fay, near Walivick, frequent, in Auguft and September. 

 The root is fucculent, and gradually rifes to a thick pedicle, 

 from an inch and a half to two or three inches long, and fome- 

 times more. The head is from two to four inches in diameter. 

 It is very foft and tender. The tubules or pores on the under 

 part are fquare, terminated with dentated and orbicular protu- 

 berances. It is intirely of a yellowifli-white, and turns to a gold 

 yellow by age. Cut tranfverfely, it mews the form of the tu- 

 bules. It ilains the fingers on being touched, like the faffron 

 clay-ochre, and diffufes a moft ungrateful fmell. It retains its 

 form, yellow colour, and fcent a long time in drying. 



25. AJh-coloured, tejjellated Mujhrome, 'with quadrangular tubules or 

 pores underneath (n). On alpine heaths. I met with it in Septem-
