Fig. 9* M. glaucus. 



THIS we alfo believe a variety of the fame fpecics. 

 It is apt to throw the httle feeds into a moniUform- 

 appearance. It is fometimes gray as well as greenilh : 

 Micheli fays it is found only on rotten apples. 



Fig. id. M. ferrugineus. 



FOUND fometimes on old ftumps of trees, decay- 

 ing hay, Sec. The ftipes is thickeft at the bafe ; head 

 irregularly powdery, and of a rulliy brown. 



Fig. II. M. rosev s. Mom'/ia ro/ea. Ba(/c/j. tab. 12. Jig. 58. 



MOST common on the decayed kernels of nuts, 

 within the fliell, though more often on other rotting 

 fubllances. The Rev. Mr. Alderfon fent me fome on 

 rotten wood. The Rev. Hugh Davies fent me fome 

 which he faid he found on Tuber folidmn. It is moftly 

 in denfe patches, compofed of numerous fibres more or 

 lefs diftindl, and round particles of farinaceous powder 

 of a rofe colour. 



Fig. 12. M. quernea. 



WE have only found this in the hollow of the great 

 oak on Hainault Foreft- called Fairlop, where it is very 

 abundant. It is compofed of branched filaments with 

 numerous ovate, powdery heads in little bundles, 

 mofi:ly of a deep orange colour. 



Fig. 13. M. chrysospermus. Bull. 504. i. 

 THIS differs from the lall in having round and 

 lighter-coloured particles compofmg the heads. It is 

 found on rotten Boleti. 



Fig. 14. M. lignifragus. 



DIFFERS from M. glaucus, fig. 9. in being in much 

 more round fafciculi. I believe, however, thefe are 

 only varieties of each other, and are the admired blue 

 mould in rotten cheefe, Sec.
