A continuous, usually thick gelatinous 
layer, composed (under the microscope) 
of branched paraphyses, gloeocystidia, and 
cruciate-septate basidia whose fertile distal 
part is separated from the stalk-like basal 
part by the intersecting vertical walls, which 
turn out to meet the outer wall of the hypo- 
basidium. The apparent color varies con¬ 
siderably, according to the thickness, the 
color of the substratum which shows through 
the clear or opalescent basidiocarp, and 
probably other factors. The collection from 
Kupehau when fresh was pinkish—Pallid 
Mouse Gray to Pale Vinaceous-Fawn, where¬ 
as the one from Ekehanui, not far away, was 
in part Pale Olive-Gray and in part colorless 
and merely pruinose; others were noted 
in the field as being yellowish-opalescent, 
bluish-opalescent, blue-white, iavender-giliy, 
light neutral gray, and deep blue-gray. In 
texture and presence of gloeocystidia and 
paraphyses S. petiolata is related to S. Gal- 
zinii and S. umhrina, from both of which it 
differs in the manner of branching of the

paraphyses, in clavate basidia, and in spores. 
The presence of the stout stalk separated by 
the vertical septa from the fertile portion is 
the clearest recognition-character. The new 
species may be accommodated in Martin’s, 
McGuire’s, or Rogers’s keys (earlier cited 
under Sebacina jarinacea ) by the addition of 
a third choice to the dichotomy separating 
S. umhrina and S. Galzinii (or S. Pulula- 
huana ): 
"Gloeocystidia similar to those of S. Gal¬ 
zinii ( Pululahuana)\ spores oblong, ellip¬ 
soid-oblong, or ellipsoid-subglobose, 7-11 
X 6-8 /x; basidia subclavate, the stalk sepa¬ 
rated by the vertical walls from the fertile 
summit... S. petiolata”

When young, and about the margins when 
mature, formed of distinct minute gelatinous 
pustules, which later are confluent into a 
reticular or apparently continuous, uneven¬ 
surfaced layer. This inconspicuous but char¬ 
acteristic fungus, originally described from 
southern Brazil, has since been reported as 
occurring more generally in tropical Amer¬ 
ica and in the eastern and central states at 
least as far north as Wisconsin and Massa¬ 
chusetts. It certainly occurs and has been 
reported (under other names) in western 
Europe, and has several times been collected 
in Hawaii. 
Four of the specimens here listed are in 
all respects quite typical, and are not dis¬ 
tinguishable from Iowa material. The five
