degenerated variety, called white-cup, which 
produces a fort of Mulhroom with fmall 
thin white head without any flelhy part, and 
generally rifes up fuddenly in the beds. This 
fort is entirely ufelefs, and often difappoints 
the gardener. It is diftinguilhable generally 
by its great abundance all over the lumps, by 
its very fine filky cobwebby nature, and its ex- 
ceeding white hoary-like appearance ; it has 
little or no fubfiance, and emits but a very 
faint fmell of the Mulhroom. 
About London, where great quantities of 
Mufhrooms are raifed for the markets, and 
confequently valt fupplies of fpawn are an- 
nually required, there are experienced Mulh- 
room-men, who, at the proper feafon, .go 
about collecting, both in town and country, 
the true fort, which they buy commonly from 
about half a crown to five or fix Ihillings per 
bulhel, according to its goodnefs or plenty.
