the genus Calostoma , Desv. 41 
of a dull green colour. Endoperidium about 2 cm. in diameter. 
Stem 2 cm. or more long by 1-1*5 cm - thick. Its nearest 
affinity is with C. orirubra. 
Calostoma insignis (Berk.), Mass. Plate III, Figs. 35, 36. 
Exoperidium ochraceous, broken into irregular lobes, which 
sometimes remain attached to the middle of the stem-like 
base. Endoperidium, smooth, ochraceous, ostiolum pale 
green, teeth 5-8, erect. Spore-sac pale green, spores globose 
coarsely spinulose, pale ochraceous, 14-J7 /x diameter. Stem- 
like base cylindrical or ventricose, smooth or lacunose.

Endoperidium 1-5-2 cm. diameter, stem-like base 3-4 cm. 
long by -5-1 cm. thick when ventricose. 
C. pachystelis (Ces.), Mass. 
Exoperidium thick, irregularly ruptured, and persistent at 
the base of the stem. Endoperidium globose, mouth umbonate, 
furnished with teeth.

Sarawak, Borneo (Beccari). 
The largest species of the genus. Exoperidium nearly 1 cm. 
thick, from 5-7 cm. across when ruptured ; endoperidium little 
more than 2 cm. in diameter; stem 4-5 cm. long by 1-5-2 cm. 
thick, internally lacunose, externally furrowed. Evidently a 
good Calostoma ; the spore-sac appears to have disappeared 
from the endoperidium in the mature specimens, and is repre- 
sented as filling the cavity of the latter in the section given by 
Cesati, which is evidently an immature plant with the thick 
exoperidium still continuous over the endoperidium, and Cesati 
says, ‘ Gleba sporifera totum peridium replens in fungo juvenili 
vel adhuc clauso.’ No mention is made of the form of the 
spores, which, judging from affinity and locality, were pre- 
sumably spherical.
