Charaoterize<i by the (usually) minute sterile liase and especially by the 
nature of the exoperidium, which is of short, stout, pallid s])ines often eouverg- 
ing in fours at the apices. Plants vary considerably in the degree of the rough- 
ness of the spores and depth of the colour of the eapillitiuni, doubtless owing to 
many being collecte<l before they wei'e properly matured. — Uuuninghani. 
498. Lycoperdon Gimnii Berk. (After Konald Campbell Gunn, 1808-1881, 
F.R.S., noted for his botanical researches in Tasmania, private secretary to Sir 
•John Franklin). — Peridium ® to (.in. (1 to 2 cm.) diameter, globose or sub- 
gloliose, bay-brown or yellowish-brown, with a small rooting base; exoperidium 
at first covei'cd with minute warts or tomentose, becoming tiocculent and areo- 
late wlien old; endoperidium bay-brown or yellowish, dehiscing- by a small, 
irregidarly torn, plane apical stoma; sterile base absent, or seldom scantily 
develo])ed. Gleba yellowish, becoming .olivaceous; columella absent; capillitium 
threads i)allid oliraceous or lemon yellow, thin walled, sparsely branched, con- 
tinuous, pitted. Spores globose, 4 to 5 g, pedicels tinted, iieuininate; epispore 
tinted yellow, finely verruculose. Solitary or in small groups on the ground. — 
Cunningh.-!m. South Australia — Big Swamj) west of Port Tuncoln (probably), 
klurray Range east of Truro (doubtful). Xew South Wales. Victoria. Tas- 
mania. IMay, August. 
A small subglobose plant with a poorly dcvelo])ed rooting base, the sterile 
base usually being absent. The yellowish nature of the gleba, capillitium and 
sjiores, S])aringly pranched, flaccid capillitium, small size of the p)eridium, and 
the furf uraeeous nature of the exoperidium, are the specific characters of the 
species. — Cunningham. 
BOVISTELLA Morgan. 
(Diminutive of Bvmsta.) 
Plants remaining attached to the place of origin, not breaking away at 
maturity: with a well-developed rooting base. Peridium globose or pyriform, 
of two layers; an external tlmi, usually fugacious exoperidkim, and an inner 
thin, flaccid, membranious endoperidium which dehisces by an apical definite or 
indefinite month. Gleba with or -vvithout a well defined sterile base ; capillitium 
of free threads, each consisting of a thick stem an<l dichotomous, tapering, acu- 
minate branches. Spores coloured, continuous, rough or smooth, globose, obovate 
or elliptical, pedicellate or apedicellate. Solitary on the ground. — Cunningham.

499. Bovistella verrucosa Cunn. (L., verrucosus, wuirty). — Peridium globose 
or shortly pryiform, up to Sin. (15 mm.) diameter; with a stnong, well-marked 
rooting base; exoperidium in the nature of a very delicate layer, soon more or 
less completely flaking away; endoperidium dingy white or p:illid tan, minutely 
and delicately tomentose, appearing almost smooth, very thin and fragile, 
flaccid, opening by an apical, irregular, indefinite plane mouth. Gleba bay-brown, 
sterile base absent; capillitium thi-eads of the usual t.vpe, pitted. Spores 
globose, 4 to 6 g, pedicels hyaline, acuminate, up to 12 g long; epispore tinted, 
finely and closely verrucose, 1.5 g thick. Solitary on the ground. — Cunningham. 
South Australia — Monarto South. September. 
The small size, pallid colour and tomentose nature of the endoperidium and 
rough pallid spores characteriso this species. 
500. Bovistella bovistoides (Cke. et Mass.) Lloyd. (Bovista, the genus; Gr., 
eid\os, a form or sort). — Peridium globose, depressed-globose or shortly pyriform, 
up to fin. (2 cm.) diameter, with a strong i;ooting base whach frecpiently 
attains a length of over fin. (1.5 cm.); exoperidium thin, w'hite, j)ersistiug as 
small areolate areas over the u])per part of the endoperidium, but, scanty or 
absent from the lower part, frequently falling a-vvay completely when the endo- 
peridium appears marked with lines arranged in an areolate manner; endo- 
peridium flaccid, (lull bay, or chestnut-brown, darker basally; mouth apical.
