(4857), p. 130, tab. 25 B; Sacc. Syll. 7. n. 203. (Type in 
Herb. Berk., Kew, n. 4473.) On the ground, Caesar’s Head ; 
mountains of South Carolina (Ravenel). 
Endoperidium -5-1 cm. in diameter; stem-like base less than 
1 cm. long. Berkeley’s measurements are in all instances 
taken from dried specimens, and consequently rather smaller 
than mine, which are taken from specimens that have been 
moistened. Agreeing with C. lurida in size, and in the smooth 
elliptical spores. 
Calostoma fitsca (Berk.), Mass. Plate III, Fig. 24. 
Simple or caespitose. Exoperidium dark brown externally, 
dingy red within. Endoperidium pale brown, subglobose, 
ostiolum vermilion, teeth erect, and forming an umbo before 
expansion, 4-6 in number. Spore-sac white, spores elliptic- 
oblong, minutely verruculose, pallid. Stem-like base stout, 
elongated, brown, costato-lacunose.

Mitremyces australis , Berk, in Herb. Tasmania (Archer), 
(Gunn); near Melbourne, Australia (Berggren) ; Lake Muir, 
Australia (Muir). 
Solitary or in clusters, two or three springing from a common 
base. The whole plant is of a dark brown colour, endo- 
peridium from 1-1*5 cm. in diameter, stem-like base 2-3 cm. 
long by 1 cm. thick. Most nearly allied to C. lutescens, with 
which it agrees in the mode of separation of the exoperidium. 
Calostoma lurida (Berk.), Mass. Plate III, Fig. 19. 
Exoperidium breaking up early into small blackish granules, 
which remain attached to the ochraceous, subglobose endo- 
peridium ; ostiolum black internally, as well as the margins of 
the 4-5 teeth. Spore-sac pale ochre or whitish, spores elliptic- 
oblong, smooth, pallid, 16-20 x 7-9 [x. Stem-like base short, 
brown, irregularly lacunose.
