1221. Secotium erythrocephalum. Tul. Ann. Sci. Nat. 
1884, 115. Sacc. Syll. vn., 152. 
Gregarious, rather long stemmed ; stein erect, smooth, naked, 
white, narrowly fistulose ; peridium innate, simple, even, smooth, 
carmine-red ; cells unequal, large, septa thin, distinct, destitute of 
flocci, basidia arising from the walls bearing 2-4 spores ; spores 
elliptic, even, brown, on long sterigmata (10-11 x 5 /a). 
On the ground. New Zealand. Tasmania. (Fig- 108.) 
1222. Secotium Gunnii. Berk, in Herb. No. 4412. Sacc. 
Syll. vii., 156. 
Small ; stem slender, 1-5 c.m. high, 3 m.m. thick, solid, equal or 
slightly incrassated downwards, pale brown; passing through the 
gleba as a columella and expanding at the apex into a thick wall ; 
peridium 1-5 c.m. across, subglobose, 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, elongate ; spores obliquely ellip- 
tical, tips acute, smooth, pale reddish-brown, 7x4 p. 
On the ground. Tasmania. 
1223. Secotium scabrosum. Che. Mass. Orev. xx., 35, 
Peridium hemispherical, depressed, dingy olive or greyish (2 
c.m. diarn.), minutely scabrous; gleba lacunose, septa gill -like, 
waved and folded, dark reddish-brown ; spores lemon-shaped, 
rather coarsely warted, pale olive-yellow (16-18 x 10 p) ; stem 
very short, almost obsolete. 
On the ground. Victoria. 
Genus 13. CHAHTODERMA. Mass. 
Peridium elongato-fusiform or clavate, tapering into a short 
stem-like base, wall rather thick, consisting of a single stratum; 
columella thick, compact, passing quite through the peridium, and 
firmly attached to the apex ; the cavity between the columella and 
the outer wall is occupied by the gleba, consisting of numerous 
interwoven septate hyplne, bearing clusters of tetrasporous clavate 
basidia at intervals; spores unicellular, coloured. Dehiscence is 
effected by the splitting of the central portion of the wall into 
longitudinal shreds, due to the shortening of the columella. 
1224. Chainoderma Drummondii. Mass. Grev. xix., 46.= 
Secotium Drummondi., Berle. in Herb. 
Clavato-fusifonn (5-6 c.m. high, by 1-5 c.m. at widest part) ; 
peridium dingy-brown, smooth, even, at length longitudinally 
fissured, columella pale ; mass of spores dingy brown ; basidia 50 
X 12 p, clavate, fasciculate ; spores broadly elliptical, with the 
remains of the sterigma usually persistent, epispore thick, smooth, 
10 x 8 p. 
On the ground. W. Australia. (Fig. 109.)
