AUSTRALIAN FUNGI.

Genus 18. TILMADOCHE. Fr. 
Sporangia stipitate, splitting in an irregular or reticulate manner, 
without columella; wall of sporangia single, very delicate, weakly, 
but not uniformly containing deposits of lime; tubes of the capilli- 
tinm at the bottom simple, forking through the whole length at a 
sharp angle, the rest straightened, therefore formed into a regular 
net; granules of lime very small, fusiform, not numerous.

Mass. Mon. 327. Sacc. St/ll. 1244. 
Sporangia lenticular, plane or concave below, usually cracked in 
many places, umbilicate, greyish-white, stipitate, nodding ; stem 
of variable length, subulate, eernuous, furrowed, whitish-grey or 
greyish-brown ; capillitium strongly developed, tubes uncoloured, 
containing very small irregular granules of lime; spores bright- 
violet, smooth, 9-10 fi.

Mass. Mon. 329,=T. viridis. Sacc. Syll. vn., 1247. 
Sporangia globose, flattened, or lens-shaped, plane below or con- 
cave, usually cracked in many places, umbilicate, yellow, greenish 
yellow, or rusty orange, stipitate, nodding, splitting irregularly, or 
in a reticulate manner ; stem variable in length, subulate, eernuous, 
straw-colour, yellow, scarlet, or ferruginous ; capillitium coloured 
the same as the sporangia ; tubes strongly developed, containing 
fusiform colourless granules of lime; spores globose, minutely 
warted, 9-11 /x.

Genus 19. LEOCARFTJS. Link. 
Sporangia irregularly splitting, with double walls ; inner wall 
surrounding the mass of spores on all sides, and giving origin to 
the capillitium; outer wall thick, passing down to the stem or 
hypothallus. Tubes of the capillitium formed into a thick net, the 
greater part of the knots weakly developed, filled with air, the rest 
very much swollen, and changed into granules of lime. 
2078. Leocarpus fragilis. Dicks. Rifki. Mon. 132, f. 93. 
Mass. Mon. 338. Sacc. Syll. 1242. 
Sporangia obovate, or somewhat roundish, sessile, or with a thin 
thread-like, coloured, rising stem ; bright, shining, containing 
coloured granules of lime ; spores dull violet, spiuulose, 12-14 fi. 
On grass, twigs, moss, etc. Tasmania. (Fig. 362.) 
Genus 20. FULIGO. Hall. 
Variable in size, deformed, diversely coloured, ajthalium com- 
pounded of variously entangled vein-like sporangia, with but little 
cohesion ; central stratum filled with spores and capillitium, outer
