VIII. .FUNGI.

Tribe VI. Tremellini. Gelatinous Fungi, with sometimes a more solid nucleus, vari- 
ously shaped, often lohed, convolute or discoid; sporophores large, simple or divided. 
Spicules elongated into threads, which are not compacted into a true hymenium. 
22. IIirneola. Substance tough, externally hispid. 
Suborder II. Gasteromycetes. — Hymenium concealed witliin the sub- 
stance of the plant, exposed only by the rupture or decay of its walls (peri- 
dium ), consisting of closely-packed cells, of which the fertile bear naked spores 
on distinct spicules. 
A large suborder, of high development, remarkable for the drying up of the hymenial 
tissues of many, whence their cavities contain a dusty mass of spores. Spiral threads occur, 
mixed with the spores, of some. 
* 
Tribe VII. Fhalloidei. Young pileus enclosed in a gelatinous stratum, and this in a 
qlobular vo/va, which bursts irreqularly and exposes it. Hymenium deliquescent. 
( Fetid Fungi.) 
23. Aseroe. Pileus cylindric, branching at the summit into forked horizontal rays, 
sheathed with the volva at its base. 
24. Ii.eodictyon. Pileus forming a globular reticulated branched network, the branches 
tubular. 
Tribe VIII. Tricbogastres. Usually globose dry Fungi. Hymenium enclosed in a 
single or double coat (peridium ), at length drying up into a dusty mass of microscopic 
threads and spores (capillitium). ( Chiefly terrestrial, puff-balls, etc.) 
25. Secotium. Pileus subglobular, stalked ; stalk sheathed with the volva at the base. 
26. Paurocotylis. Globose. Peridium of closely interwoven tlocci. 
27. Geaster. Peridium splitting into reflexed segments. 
28. Trichoscytale. Cylindric. Outer peridium hard, surrounding the base of the 
capillitium with a volva. 
29. Bovista. Globose. Peridium like parchment, cracking off in large flakes. 
30. Lycoperdon. Globose or pyriform. Peridium papery, persistent, warted or tuber- 
cled towards the apex. 
31. Scleroderma. Subglobose. Peridium corky, bursting by an indefinite aperture. 
Tribe IX. Myxogastres. Usually minute Fungi, pulpy when young, of various forms. 
Peridium usually globose , single or double , containing a dusty mass of flocci, mixed with 
spores. 
32. JEthalium. Indeterminate, adnate, globose or oblong, pulpy masses. Outer peri- 
dium floccose. 
33. Diderma. Minute. Peridium globose, double, outer polished. 
34. Didymium. Minute. Peridium subglobose, single, outer furfuraceou3. 
35. Stemonitis. Minute. Peridium globose or cylindric, single, evanescent, traversed 
by the stipes. 
Tribe X. Nidulariacei. Peridium of various forms, bursting at the apex horizontally , 
containing separate sporangia, in which the spores are formed. 
36. Cyathus. Peridium of 3 membranes. 
37. Crucibulum. Peridium of a uniform spongy consistence. 
Suborder III. Coniomycetes. — Very minute Fungi, including rusts, 
bunt, smut, various mildews, etc. Hymenium 0. Spores abundant, conspi- 
cuous, often large, surrounded by a perithecium or naked, terminating incon- 
spicuous threads. Threads often arising from a creeping mycelium. Peri- 
dium ( perithecium ) when present very delicate and evanescent.
