Chitonia.
Togaria AGARICACEÆ 121
Saccardo (Sylloge Fungorum, vol. v. p. 761) makes Berkeley’s
Acetabularia analogous with Gillet’s LocelUna. The two genera are
quite distinct ; LocelUna is not represented in Britain.
LocelUna.
Pileus smooth, glabrous.
Gills broadly adnate.
Stem fibrilloso-annulate.
Acetabularia.
Pileus sulcate, white-furfuraceous.
Gills adnexo-free.
Stem, simple.
556. A. aeetabulosa Mass. (from the cup-like volva; acetabulum, a
vinegar-cup) a b.
P. convex, salmon; mid. sienna-reddish, white-furfuraceous; marg.
