Globose, depressed in the centre, papillate, sometimes hol-

 spotted, nearly smooth, rigid, crustaceous ; peridium thick,

The original specimens of Vittadini are minutely granulated under a lens, 

 a character which does not appear in our specimen. The sporidia are alike, 

 and at once distinguish it from E. variegatm, the only species with which it 

 can be confounded. The smell is very powerful, in which respect again it 

 does not agree with Vittadini's species. It is, indeed, probable that it will 

 prove new, but on the authority of a single individual, not in very good con- 

 dition, it woul 1 be rash to do more than indicate its nearest affinity. The 

 outer rind in the specimen when gathered was black, the inner of a dull yel- 

 lowish-white . — M.J.B.

Mycelium yellow (or yellowish-grey), inconspicuous ; cortex 

 thick, hard, ochraceous-yellow or golden-yellow, rough, with 

 thick pyramidal and obtuse, or narrow, pointed, and fragile 

 warts, or only granulated ; peridium reddish-brown and varie- 

 gated ; asci 2-4 spored ; sporidia opaque, blackish-brown. — Vitt.

Differing from E. granulatus in its more muncated surface, less deep black, 

 and smaller sporidia, but essentially in the substance of the coriaceous 

 covering, being variegated with brown dots. Sporidia ■02-'022 m.m. diameter.
