YII. — On the Red Mould of Barley, 

 By Charles George Matthews. F.O.S., F.I.G. 



{Bead 11th April, 1883.) 

 Plates V. and VI, 



During the malting season of 1879-80, when the quality of the 

 majority of samples of English-grown barleys was decidedly 

 inferior, my attention was directed to the frequent occurrence of 

 so-called " red corns " amongst the couches at a small malt-house 

 where various samples of English barley were being worked up. 

 Since it was evident, on a very cursory inspection, that the red 

 corns owed their peculiar appearance to a definite mould-growth, I 

 made search in such treatises on the moulds as were at my command, 

 for information bearing on this mould in particular ; but was unable 

 to find any reference to it. It then occurred to me to communicate
