AUSTRALIAN FUNGI. 
stem slender, erect, smooth, even, fistulose, paler than the pileus 
(2-2^ c.m. long, scarcely 1 m.m. thick). Gills broadly adnate, not 
crowded, plane lemon yellow. Spores minute, 5-6 x 3 /x, white. 
On tree ferns. Victoria. {Mrs. Martin , 524.) 
Agaxicus (Flammula) xubxa, Cke. Sf Mass. 
Pileus fleshy, convex, at length depressed, apparently dry, 
smooth, even, shining (2J c.m. broad), red, with a tinge of purple; 
stem equal, hollow smooth, paler than the pileus (4 c.m. long, 
4 m.m. thick). Gills rather broad, not crowded, adnate, with a 
decurrent tooth, at first coloured like the pileus, then dusted with 
the ferruginous spores, which are elliptic, 7x4 /x. Flesh, and 
substance of the gills, permanently roseate. 
On the ground. Oakleigh, Victoria. (Mrs. Martin , 526.) 
CHA1NOSEEMA, Mass. (». g .) 
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 hyphae, 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. 
Allied to Podaxis in the structure of the gleba, distinguished 
by the unmistakable tetrasporous basidia bearing the spores on dis- 
tinct sterigmata, also in the peculiar mode of dehiscence; in the 
present genus the gleba is not lacunose as in Secotium. 
Chainodexma Dxummondii, Mass. 
Clavato-fusiform (5-6 c.m. high, by 1*5 c.m. at widest part), 
peridium dingy brown, smooth, even, columella pale ; mass of 
spores dingy brown ; basidia 50 x 12 /x, clavate, fasciculate; spores 
broadly elliptical, with the remains of the sterigma usually per- 
sistent, epispore thick, smooth, 10x8 /x. Secotium Drummondii, 
Berk, in Herb. 
On the ground. Swan River. (Drummond.) 
The peridium never becomes free from the stem at the base, as in 
Podaxis , but on the shortening of the columella, due to contrac- 
tion, is bulged outwards and split into ongitudinal shreds, leaving 
gaping chinks through which the sporels escape. 
Fuccinia xuxnicis-scutati (D.C.), Winter Pilze 187, Sacc. Syll. VI., 
2214. 
Sori scattered, or disposed in a circle, irregularly rounded, or 
(on stems and petioles) elongated, girt by the torn epidermis, 
brown. Uredospores ellipsoid or ovoid, rarely globose or oblong 
(26-40x20-28 fx), aculeate, yellow-brown ; teleutospores oblong, 
or clavate, a little constricted in the middle or not at all, incras- 
sated at the apex, rounded or somewhat attenuated, narrowed at
