Whereas I have mention’d, that a fort of Fungus , of a light-brown 
Colour, grows over the Seed-veffels of the Filix mas ; this is to be 
underftood to have that Appearance, when the Seeds are full-ripe, 
and the Veffels containing them are prepared to burft : For I have 
fince view’d them, foon after they begin to appear, and alfo when 
the Seed-veffels are nearly grown to their full Size ; at which times 
the faid Fungus is a fine Membrane of a bright Green, intirely cover- 
ing the Tuft of Seed-veffels like a Cap, and clofely adhering to the 
Surface of the Leaf of the Plant : But when the Seed-veffels are 
arriv’d at Perfection in Size, and able to bear being expos’d, it 
begins to recede from the Leaf, and to hang over them in form of 
an Umbrella • and as they grow ripe, it gradually changes brown, 
and curls up a little, making the Appearance firft-mention’d.
