color, Spores hyaline, 5 X 10, slightly curved, unilateral, apicu- 
lat e, 
Were we to determine this from books we should call it 
Exidia saccharina, but we know this in Europe and it is not that 
species. The color might be compared to brown sugar but better to 
a raisin. We do not find it in Ridgway, but pecan brown is not far 
away. While it has no papillae wo put it in Exidia on the spores. 
As previously stated the line between Trerne 11a and Exidia is hard to 
draw. In general appearance this is rather a Tremella. The color 
is somewhat like that of Naematelia nucleata when old. It dried 
away leaving hardly a trace and it grew on frondose bark. 
We published this in Myc. Notes No,31, p.898 as Exidia Uva 
Passa (in duplicate) having used the name (54, 774) for a plant from 
Japan, We are not sur: that our American plant is different from the 
Japanese but it appears to us to have a more reddish color and 
smaller spores but it is practically the same. 
ARACHNION SCLERODERMA PROM MISS A. V. DUTHIE, SOUTH APRICA 
(Fig. 1774 ).- This is the second collection of this very distinct 
species forwarded by Miss Duthie, For a hundred years Arachnion 
was known from three or four so called species but practically only 
one, Arachnion album. But Miss Duthie has found two very distinct 
species that no one else has ever collected, Arachnion Scleroderma 
we now believe is not very well named. It has more the general 
appearance of a Lycoperdon than a Scleroderma. The cortex when old 
takes a scaly appearance suggesting the squamules of a Scleroderma, 
but when in good condition, as these specimens are, it is exactly 
the cortex of a Lycoperdon. We present (Pig.1774) another illustra- 
) tion of this interesting species and also Fig. 1775 an enlargement 
of the cortex spines. Until Miss Duthie found this species the 
cortex of all Arachnions known was smooth. 
PQDAXON ANOMALUM FROM DR, J, B, CLELAND, AUSTRALIA (Fig, 
1776 ).- This is really a new genu3 but we do not lik) to propose 
one on a single old half specimen in bad condition. Dr. Cleland 
found but a single old specimen and sent us half. It is intermediate 
between Podaxon and Secotium, It is a Secotium in general appear¬ 
ance but Secotium does not have powdery gleba. The dehiscence can 
not be told surely from the specimen but the peridium is soft and 
fragile and seems to flake off in the manner that Gauloglossum is 
said to dehisce. This is entirely at variance with any Podaxon. The 
columella, thick at the base, rapidly tapers and does not reach the 
apex of the peridium. This is another feature of which I know no 
similar case. The gleba is light brown, floccose, powdery. The 
microscope resolves it into pale yellow, globose or elliptical, smooth 
spores, 10-12 X 12-14 mic, which are mixed with abundant, hyaline 
hyphae fragments, apparently, the remains of the basidia. It does 
not have true capillitium. We place it provisionally in Podaxon on 
account of the gleba nature, and Podaxon is one of the few puff ball 
genera in which basidial remains are found in the gleba. This is a 
very exceptional and curious species and I hope our Australian 
friends will'watch for further collections.
