This plant which I only know from Kuropean specimens I am 
convinced is practically the same plant as our saccatus. (*) With the 
exception of the indeterminate mouth, and the tendency of the exope- 
ridium to split into two layers I can see no other difference. The idea 
that fimbriatus can be known by its “fimbriate” mouth is an error. 
The mouth does not differ from several other species with indetermi¬ 
nate mouths. The plant is recorded several times from this country, 
but I think determinations are based on saccatus.

21—GEASTER SACCATUS. 
Unexpanded plant globose. Mycelium universal. Kxoperidium 
cut to six to twelve segments about half way, the limb deeply saccate. 
Mycelial layer adnate to fibrillose. Fleshy layer when dry, thin, ad- 
nate. Inner peridium sessile, globose, with a determinate fibrillose 
mouth. Spores globose, almost smooth, 4 me.

Although the plant differs in being more deeply saccate and 
having a determinate mouth, I believe it is only the American expres¬ 
sion of G. fimbriatus of Europe. It is a very common little plant in 
this section, growing gregarious over rich soil and decaying' leaves in 
woods. Geaster saccatus is a name given to a South American plant 
by Fries and applied to our species by apparently universal consent. 
I do not know however, that anyone really knows that it is Fries’ 
plant. It certainly is not the plant that Spegazzini distributed from 
South America as saccatus.
