the genus Calostoma , Desv. 
The above incontrovertibly proves that the plant described 
by Desvaux is the same as Mitremyces lutescens , Schw. ; hence 
Calostoma , having priority, must replace Mitremyces . 
Persoon’s figure quoted by Desvaux is very characteristic 
of the plant intended, whereas the same cannot be said for 
the figure of Nees, which does not represent a real plant, yet, 
as the species of this genus are not generally known to myco- 
logists, a preconceived idea is formed from the last-named 
figure. 
Calostoma Junghuhni (Schl. et Miill.), Mass. Plate III, 
Fig. 21. 
Exoperidium ochraceous, with sometimes a greenish tinge, 
soon breaking up into irregular warts, which persist for some 
time on the broadly elliptical ochraceous endoperidium, mouth 
vermilion, teeth 4-6, erect at first. Spore-sac pale, spores 
globose, coarsely tuberculose, pale ochre, 14-18 /x diameter, 
stem-like base composed of more or less parallel mycelial 
cords above, ending in a thickened mass of finer interwoven 
strands.

M. Beyrichii, Sch. et Mull, l.c. Java (Junghuhn), Sumatra 
(Junghuhn), Sikkim Himalayas, 8coo feet (Dr. G. King). 
Variable in size, endoperidium -5-1-5 cm. high; stem-like 
base 1-2 cm. long. In some specimens the warts of the 
exoperidium are persistent, in others disappearing at an 
early stage of development, leaving the endoperidium smooth 
externally. 
Calostoma Berkeleyi , Mass., n. sp. Plate III, Fig. 33. 
Exoperidium ochraceous externally, inside reddish brown, 
ruptured irregularly at the apex and breaking away, leaving 
the subglobose, ochraceous endoperidium smooth ; ostiolum 
vermilion, teeth 5, acute, erect. Spore-sac pale, spores globose, 
minutely verruculose, very pale ochre, 7-9 /x diameter, stem- 
like base ochraceous, irregularly lacunose.
