Tulostoma Wrightii, BerTc. in Serb. 
Stem 6 c.m. high, 4 m.m. thick, hollow, equal, ochraceous, even, 
glabrous ; peridium spherico-depressed, 2 c.m. broad, minutely 
umbonate, pale, ochraceous, glabrous, the wall of the umbo dis- 
appears at maturity and forms a small circular stoma; mass of 
spores yellowish-brown ; threads of capillitium hyaline, thick- 
walled, aseptate, equal, very long, branched, axils lunate, 5 y diam. ; 
spores globose, pale yellow-brown, minutely warted, 5-6 y diameter. 
On the ground. Rio Grande, North Mexico. (Wright). (Type 
in Herb. Berk.) 
Distinguished from Tulostoma Myenianum in the entire mouth 
and the hollow, even and not striated stem. 
Tulostoma album, Mass., n. sp. 
Stem 1-5 c m. high, *5 m.m. thick, ochraceous, longitudinally 
wrinkled ; peridium globose, minutely umbonate, white, glabrous 
and shining ; mass of spores ochraceous-cinnamon ; capillitium 
dense, threads hyaline, thick-walled, often branched, axils lunate, 
aseptate, variable in thickness, from 8-12 y\ spores yellow-brown ; 
globose, coarsely warted, 10-11 y diameter. 
On the ground. Israelite Bay, W. Australia. (Type in 
Herb., Kew.) 
Resembling Tulostoma brachypus in habit, but differing in the 
pure white peridium and the small stoma with an entire margin. 
Hydnangium nigricans, Kalchbr. (omitted from Saccardo), described 
in Orevillea , Vol. X., p. 107. 
Hydnangium Tasmanicum, Kalchbr. in Serb. 
Subglobose, 2-5 c.m. diameter; peridium thick, dark brown, 
rugulose when dry, sterile base entirely absent, cells of the 
gleba large, irregularly angular, 1-2 m.m. in diameter, septa thick, 
ochraceous, not splitting ; basidia clavate, tetrasporous, sterigmata 
short, spores globose, brown, epispore thickly covered with large, 
irregular warts, 13-14 y diameter. 
On the ground. Tasmania. (Specimen from Kalchbrenner in 
Herb., Kew.) 
Secotium leucocephalum, Mass., n. sp. 
Small ; stem 1-2 c.m. long, 3 m.m. thick, solid, equal, white, 
even, continued through the gleba as a columella that expands at 
the apex into the wall of the peridium, and gives off laterally 
several white branched plates ; peridium hemispherical, umbilicate 
below, l*5-2 c.m. across, white, smooth, even, becoming contracted 
and corrugated when dry ; gleba orange brown, cells subequal, 
small, irregularly angular, septa thin ; basidia broadly clavate, 
tetrasporous, sterigmata very slender, elongated, spores broadly 
elliptical, apiculate, distinctly warted, yellow-brown, 8x5 y. 
On the ground. New Zealand. (Type in Herb., Kew.) 
Readily distinguished from all known species by the white stem 
and peridium, and the broadly elliptical warted spores.
