H a b . On the superior surface o f the leaves of the common Birch {BetuUi
alba'); rarely on the inferior surface. Balmuto, Miss E. and M. Boswell.
Not uncommon in shady places, as Roslin and Auchindenny Woods, Ra-
velrig-toll Moss, &c. Spring and summer.
Deep crimson, in the mature state, rather pale when young ; very irregular
in form, effused or confluent, sometimes covering nearly the whole leaf
in one uninterrupted mass, at others merely scattered or sprinkled over
the surface, appearing as if it had been dashed on by accident. In old age,
the colour becomes somewhat faded and dingy. Tubes {sporidio,) of so
irregular a form, as to appear, under a pocket-magnifier, like a mass of granules
; under a higher power they are found to be chiefly capitate, many
however, being club-shaped, somewhat turbinate, or even what may be
termed hammer-shaped. Under the highest power, they retain more or
less of a pink colour.
This very beautiful Erineum has been by many authors
confounded with E. hetulinum of R e b e n t i s c h . A l b e r t i n i
