On rotten, friable wood of Ar to carpus 
incisus. Ebon, IX. 10.46, 1366. 
Like a number of European and American 
specimens, that from Ebon was a barely 
perceptible bloom when living, and dried is, 
except under the binocular, wholly invisible. 
It can readily be recognized in microscopic 
preparations by the four inflated epibasidia 
and the thick-allantoid spores. The latter in 
the collection cited are mostly 7-7.5 X 3.5-4 
P , relatively stout, like the type, but very little 
tapered toward the ends, more like some 
Iowa material. Previously reported from 
western Europe and from the northeastern 
quarter of the United States, the southern¬ 
most station being in Missouri. Martin 
(1939: 242) has reported two other species 
of Tulasnella from the tropics: T. violea, 
a common species of western Europe, the 
northeastern states, and southeastern Canada, 
from Colombia; and T. sphaerospora, un¬ 
known elsewhere, from Panama. Gloeotu- 
lasnella calospora occurs in Hawaii.

On decorticate wood of Artocarpus in¬ 
cisus. Likiep: Likiep I., 1301. 
A grayish-pruinose growth showing under 
the microscope repent mycelium; obovate, 
aseptate hypobasidia bearing (usually) four 
tubular epibasidia like those of a tremella; 
and oblong-ellipsoid spores. The shape of 
the spores reaches the extreme of elongation 
known in this species, quite like Figure 2(g) 
of the Iowa paper. Hitherto reported from 
the Austrian Tyrol and central France in 
Europe, and in the Western Hemisphere from 
southern Canada and the northern states. In 
comparing the Likiep specimen with main¬ 
land material, I observed, in D. P. R. 144 
PACIFIC SCIENCE, Vol. 1, April, 1947 
from Iowa, basidia with five well-developed 
epibasidia. More than four epibasidia or 
spores apparently are developed elsewhere in 
the Tremellales only in Gloeotulasnella.

On rotten, friable wood of Artocarpus 
incisus. Jaluit, 1380. 
A thin cinereous-buff crust, under the 
microscope showing irregularly linear gloeo- 
cystidia with often yellow-granulose content, 
ellipsoid cruciate-septate basidia, and obtuse 
cylindric spores. The fructification cited is 
young, and thinner than is usual for the 
species. Its spores, which have the form 
characteristic of S. cinerea, are smaller than 
in most collections (7.5-8.5 (-10) X 4-4.5 
(“5) /x), and near the lower limit of size 
published for the species. The form of the 
basidia and the degree of compactness of the 
hymenium, both significant characters in the 
subgenus Bourdotia to which the species be¬ 
longs, are typical. 
The two synonyms given are an addition 
to those cited in previous discussions. The 
comparison of Moller’s descriptions with 
good material of S. cinerea leaves little need 
for hesitation in equating his Exidiopsis to 
the present species. Acceptance of that 
synonymy extends the range of S. cinerea to 
southern Brazil; its known range already 
stretches from Ontario to Panama, from 
Massachusetts to Oregon, and in Europe 
from Finland to Italy.
