Depressed, minute, pale when young, afterwards dark red- 
dish. Spots oblong, often confluent. Tubes somewhat va- 
riable in shape, but generally much rounded, with truncated 
summits. It has not yet been discovered in Great Britain, but 
is most probably a native. A variety of it is said to grow up- 
on the purple beech, particularly in Switzerland. It should be 
gathered in summer,

E. hypophyllum maculaeforme irregulare rubiginosum, tubis ova- 
tis vel sub-orbiculatis truncatis. 
Hab. In foliis Aceris platanoidis; vere, aestate, autumno. 
Colour rich, dark, reddish. Spots usually distinct, irregular 
in figure, depressed. Tubes minute, very short, sub-orbicular, 
apex generally truncate. Albertini and Schweiniz have com- 
mitted an error in identifying this species with that which grows 
upon Acer pseudo-plantanus^ as no two species can be more dis- 
tinct. This is another instance of the necessity of microscopical 
accuracy. E. curtuni is extremely rich and beautiful, and con- 
fined to the inferior surface of the leaf. Like E. acerinum^ it 
may be gathered during the greater part of the year. It is a 
native of France, Germany, and Switzerland.
