Rev. Mr. Kinav's Ob/ervations upon certain Fungi. 113 
Duf Brand (d). - Here its ufual name is Smut or Burnt Corn. This 
. fpecies is common to wheat, oats, barley, and rye. I have alfo feen 
Feffuca fluitans, and fome other graffes, affected by it. Itis fcent- 
- lefs, and confumes not only the farinaceous part of the grain, but 
even the arillus and chaff, difperfing itfelf entirely before the corn is 
cut; fo that the injury which it occafions is confined to the quan- 
tity of grain deftroyed by it, which is not very great in any feafon. 
I have feen, more than once, half an ear of corn affected by this

Barley and oats are more frequently attacked by it than "wheat ; 
but this may be accounted for by the latter being ufually drefed for

powerful magnifier, and found that it confifted of a number of mi-

fimply called Brand or Bladders. This fpecies does not eat through
