MUCOR BOTRITIS. 



BOTRITIS PARASITICUS. Perfoon Obfervationes myco- 

 logiccp.^ tab. 5. Jig. 6. 



Very frequent on the Shepherd's Purfe, T:hlafpi 

 Burfa-pajloris., as is the Uredo Tblafpi, tab. 340. This 

 has longer flems than that, which are often not per- 

 ceptible, and grows on the outlide of the plant, with- 

 out the cuticle for a covering. May this not be the 

 fame one lefs deeply feated in the plant ? 



TAB. CCCLX. 



FARINARIA seminaria. 



1 HIS little production, found on leaves of a Willow, 

 not yet defcribed I believe, was fent me by the Rev. 

 J. Holm of Cambridge. It appears to agree with fome 

 other things in my collection which are not referable 

 to any known genus. I therefore call it Farinaria, being 

 chiefly compofed of fine powder. 



No. I. 



Forms a little white neft holding black compacted 

 powder-like feeds, if I may fo call them ; fome I found 

 empty, with the impreffions remaining where thefe 

 feeds feemed to have been. 



No. 2. FARINARIA aurantiaca. 



Are fomewhat ovate particles fcattered on the leaf, 

 of an orange-colour, more or lefs in bundles ; fome 

 in a compacted mafs, others forming a kind of neft 

 mixed with a few cottony filaments towards the edges. 



No. 3. FARINARIA rosea. 



Rofe coloured particles rather indiftinCt, and neftling 

 with fome hairs at the extremities more or lefs enclof- 

 ing them.
