NEW OR IMPERFECTLY KNOWN GA8TROMYCETES. 
Secotium Gunnii, Berlc. in Herb. 
Small; stem slender, 1*5 c.m. high, 3 m.m. thick, solid, equal or 
slightly incrassated downwards, pale brown, passing through the 
gleha as a columella and expanding at the apex into a thick wall ; 
peridium 1*5 c.m. across, sul «globose, deeply umbilicate below, pale 
brown, smooth ; flesh of stem and wall of peridium whitish ; gleba 
brown, cells small, irregularly polygonal ; basidia clavate, tetras- 
porous, sterigmata very slender, elongated, spores obliquely ellip- 
tical, tips acute, smooth, pale reddish-brown, 7 X 4 /x. 
On the ground. Sulphur Springs, New Zealand. (Gunn.) 
(Type in Herb. Berk., Kew.) 
Secotium erythrocephalum, Tul. 
Basidia cylindraceo-clavate, tetrasporous, sterigmata slender, 
elongated, spores elliptic -oblong, smooth, apiculate, pale yellow- 
brown, 10-11 x 5 p. 
Gyrophragmium Texense (B. Sf C.), Mass. 
Stem erect, 7-8 c.m. high, lower half incrassated and enclosed in 
an adnate volva that becomes free and fibrillose at the margin, 
solid, attenuated above the volva and expanding at the apex into 
the thick wall of the peridium, which is at first continuous with 
the volva, eventually breaking away in a circumscissile manner 
and forming an agaric-like pileus ; trama consisting mostly of 
parallel lamelliform plates, rarely anastomosing laterally ; lamellas 
crowded, almost free from the stem or columella, about 1 c.m. 
deep, basidia clavate, tetrasporous, sterigmata very slender, 
elongated ; spores cinereous-brown, subglobose, epispore thick, 
smooth, 4 {A diameter.

On the ground.- W. Texas. (Capt. Pope.) (Type in Herb. 
Berk., Kew, No. 4416.) 
The present species closely resembles Gyrophragmium Delilei, 
Mont., and as a genus is distinguished from Secotium by the 
peridium breaking away from an outer portion of the stem that 
remains as a volva, and in the gleba having its septa arranged in a 
lamelliform manner instead of anastomosing to form an irregularly 
cavernous structure. 
Calostoma aeruginosa, Mass., n. sp. 
Kxoperidium even, becoming broken up into small, irregular and 
verdigris-green squamules ; endoperidium subglobose, dingy green, 
1-15 c.m. diameter, ostiolum red inside, margins of the 5 suberect, 
acute teeth, orange; spore-sac pale; sp«*res elliptical, warted, pale 
yellow. 12 x 6 p\ stem-like base, irregularly lacunose, dirty brown, 
4-6 c.m long. 
On the ground. Beenak, Victoria, Australia. (Type in Brit. 
Mus.) 
Considered by the late Mr. Broome to be identical with Calostoma 
(=Mitremyces) viridis , B., with which the present plant agrees in
