1771. Botrytis citxina. licrh. " Lemon-coloured Botrytis." 



At first white ; fertile flocci erect, articulated, branched ; 

 branches subcymose, lemon-coloured, as well as the obovate 

 spores. — Berh. Ann.N.II. no. 127, t. 8,/. 12. 



On dead twigs of cherry. Summer. King's Cliffe. 



Forraincf tliin delicate mucedinous patches, about an inch across ; mycel- 

 ium nearly white, as indeed is the whole plant at first. {J^^^<J- 2G4.) 



1772. Botrytis Jonesii. B.^'Br " Kectangular Botrytis." 



Flocci erect, branched above, branches and branchlets diver- 

 gent, mostly opposite, ultimate ramuli fasciculate, central al- 

 ways sterile, very acute ; spores subglobose, echinulate. — B. ^ 

 Br. Ann. N.H. no. 760, 1. 15,/. 12. 



On dung of dogs, rabbits, &c. Woolwich. Wothorpe. 



Flocci erect, tinged with fawn colour, simple below, with a few straight

 again divided once or twice in the same way, the central one being always

 each tipped with a sub-globose echinulate spore ("0003 in.) '0075 m.m. long. —
