elongated, oval plant with a protruding mouth. Delicatus is a de¬ 
pressed globose plant with no protruding mouth. 
From G. mammosus which this plant closely resembles in gen¬ 
eral, having the same thin hygroscopic peridium, it can be distinguished 
by its mouth. From small specimens of G. hygrometricus with which 
it agrees as to its mouth, it can be at once distinguished by its thin 
peridium and small spores.

3—GEASTER DRUMMONDII. 
Exoperidium rigid, hygroscopic, strongly incurved when dry, 
cut (about ~/z deep) to usually ten linear segments. Mycelium and 
fleshy layers absent in all specimens I have seen. Inner peridium 
globose, smooth, firm, sessile, having a short, conical, strongly silicate 
mouth, not seated on a definite area. Columella linear (?) (*). Capil- 
litium simple, tapering, about thickness of spores in thickest part. 
Spores globose, rough, 5-7 me. 
Fig. 1 8 . Geaster Drummondii. 
The little plant is apparently rare. I first received it under the 
name striatulus from Dr. Hollos, Hungary. Afterwards I found it in 
Ellis’ Exs. (No. 110) in Washington, Philadelphia and New York, 
labeled mammosus, (cfr. Myc. Notes, p. 71, No. 162, where however, 
the reference to Ellis’ exsiccatae is given in error as 109). Hollos who 
is familiar with this small plant in Hungary, has examined specimens 
of G. Drummondii of Berkeley from Australia, and pronounced it the 
same plant, only larger specimens. We really see no essential differ¬ 
ence in Cooke’s description (.save size) of the two plants in “Australian 
Fungi’’, and we believe Berkeley’s illustration in Hooker’s Journal is 
this plant. We think there is no question but that Kalchbrenner had 
the plant in view in his description of striatulus, (Grev. vol. 9, p. 8,) 
though he gives a wrong synonym. Henning beautifully illustrates 
the little plant from South Africa under the name G. Schweinfurthii, 
(Eng. Bot. Jahrb. Vol. 14, t. 6, f. 7.) 
(.*) Very indistinct in specimens examined and not clearly made out.
