502. Discisecla pedicellata (Morgan) Hollos. {Pcdicellatus, possessing pedicels 
or little stalks, in reference ta the spores). — Peridiium up to -l.-|in. (;i cm.) 
diameter, depressed-globose or lenticular, attached by a small rooting base; 
exoperidium a thick sand-case, of hyphae and del>ris iininixed, grev or brown, 
flaking away save a small discoid basal portion; endo[)eridium tougli, membriui- 
icus, chestnut-biown or umber, smootli, shining, dehiscing by a small apical 
plane stoma. Gleba purplish, pulvenilent ; capillitium pallid chestnut, of the 
usual type. iSpores globose, 8 to 10 y. diameter (including verrucae), pedicellate, 
pedicels uj) to 25 y long, stout, tinted; epispoie chestnut-brown, coarsely and 
strongl.v vermcose or verrucose-echinulate. Solitary on the ground. — Cunning-

The species is characterised by the (usuall.v) large size, firm, leathery, uml)er, 
polished eniloperidium, indefinite plane stoma, and especially by the long- 
pedicellate, coarsel.v roughened spores. The spore markings vary somewhat in 
different collections, in some being strongly verrueose, in otliers verrucose- 
echinulate. The length of the spines may vai'.v from 1.5 to^ 0.5 y . — Cunningham. 
503. Disciseda hyalothrix (Cke. et Mass.) Hollos. (Gr., hyalos, glass, a clear 
transparent stone; thrix, a hair). — Peridium up to lin. (2.5 cm.) diameter, 
depressed-globose; exoperidium in the nature of a sand-case, flaking away 
irregularly, save a small attached basal portion; endoperidium umber or ])urplisli, 
smooth, tough, membranous, dehiscing by an irregular, plane, apical stoma. 
Gleba dai'k olivaceous, becoming dark purple, pulverulent; ca{)illitium tlireads 
tinted, of th.e usual type. Spores globose, 10 to 12 y, pedicels short, up to 15 
y, stout, tinted; epispore deep chestnut-brown, densely and finely covei'ed with 
tinted or liyaline verrucae, which appear areolate in consequence of their close 
arj'angcmnit. Solitary on the grouml. — Cunningham. South Australia — Adelaide. 
New South M'ales. Victoria. June, July, October. 
Characterised by the ])edicellate, (dosely and densely verrueose spores. The 
verrucae are densely packed and somewhat irregulai- in shape and size, and con- 
secpu'ntly in surface view the epispore appears somewhat areolate. The plane 
stoma is also characteristic. The gleba may be purplish or olivaceous. — 
Cunningham. 
504. Disciseda Candida (Schwein.) Lloyil. (L., Candidas, shining, white). — 
Peridium up to l-fin. (3 cm.) diameter, depressed-globose; exo])eridium thick, 
firm, of hyphae and vegetable debris immixed, breaking away circumscissilely 
from the base; endoperidium ferruginous to umber, tough, covered in part by 
a reticulate, gelatinous layer; dehiscing by a basal, fimbriate, mammose stoma. 
Gleba olivaceous, und)er or purplish, pulverulent; capillitium threads pallid 
chestnut, of the usual type. Hpores globose, 3.8 to 4.5 y, with stumps only- of 
the pedicels remaining; epispore ])allid chestnut-brown, very finely verruculose, 
almost smooth when x 1,000 times. Solitary or in small groups in pastures; 
hypogaean. — Cunningham. South Australia — ^Between Moorilj'anna and Erna-

Characterised by the almost smooth spores, absence of a definite pedicel, and 
fimbriate mammose stojua. According to Alorgau the stoma is situated at the 
base of the jilant. The gleba is olivaceous when ymung, deep umber when old; 
frcc|uently' in Australian plants identical in all other respects, it is tinged with 
piurple. — Cunningham. 
505. Disciseda cervina (Berk.) Cunn. (L., cervinus, fawn coloured). — Peridium 
up to more than 14in. (4 cm.) diameter, depressed-globose; exoperidium thick, 
brittle, flaking away irregularly save at the base; endoperidium tough, membran- 
ous, purplish or tan coloured, furfuraceous, dehiscing by' a fimbriate, mammose
