HIRNEOLA 
(Hirnus, a jug—from the shape when young) 
H. auricula-judae, “Jew’s-ear.” Plate XXVI. 8. 
Sph. cup-shaped or ear-shaped, dark brown, much like 
Peziza vesciculosa when young, thin and elastic, somewhat 
gelatinous at first, rigid when dry. “ 1-3 in. or more 
broad; upper substance corrugated, the plaits branching 
from the middle part, where they are strongest and some¬ 
what convoluted, so as to give an idea of a human ear ; when 
the plant grows on a perpendicular stump or tree it turns 
upwards” (Berkeley.) On living and dead elder and elm, 
frequent throughout the year. 
EXIDIA 
(Gr. exidio, to exude—from the exuding receptacle) 
E. glandulosa (from the glandular hymenium), “ Witches’ 
Butter.” Plate XXVI. 3. 
Cup-shaped at first, resembling a Peziza, then flattened 
above and more or less folded below and somewhat hairy, 
varying in colour from grey to nearly black. About 1 in. 
diam. Common in aut. and win., on dead branches of oak 
and other trees. Easily recognised by the glandular 
hymenium and gelatinous substance. Bulgaria polymorpha 
differs in the tough rubbery substance, and is an Ascomycete. 
E. recisa ( vecido , to cut short—from its lopped appearance) 
is umber, brown, with plane hymenium ; common on willow 
and poplar in aut. and early win. E. albida (albus , dead 
white—from the whitish hue) is frequent throughout aut. 
and win., on dead branches of various trees, forming whitish 
folds that become brownish or lavender at maturity.
