"Dear SIR , 
Head Feb. 1 5 . TT offer you a fhort Account of a Mi- 
1 749‘ crofcopic Object, together with a 
Specimen of the fame, for your own Obfcrvation, 
at leifure. 
Some Days ago, happening to take Notice of a 
Quantity of what we commonly call Mould *, on 
the Bark of fome Fire-Wood, 1 had the Curiofity 
to view it with a Lens, of about an Inch Focus, which 
I carry about me, when I found ic to confift of Num- 
bers of minute Fungus’s , whofe regular Appearance 
invited me to examine them in the Microfcopc, 
with a good Magnifier ; upon which their fpherical 
Heads feemed as if they had been nothing elfe but 
Globules of Seeds j at the fame time, I obferved 
fevcral Seeds adhering to the tranfparcnt Footftalks, 
which fupported the Heads, and many fcattered on 
the Glafs-Plate, whereon the Subftancc was placed, 
in order to be viewed. And here I had an Oppor- 
* Of a br'gbt verdegrife Colour.
