laming the fruit immersed in them , generally strung on threads ; mostly of a 
grass-green or greenish colour , sometimes purple. They grow in fresh water , 
streams , springs , ditches , and stagnant waters; sometimes in damp woods ) and 
some in the sea. 
Confer'Na. Filaments articulated, uniform, simple or branched, containing 
the seed within them. No external fruit. 
E. The section Tremellinje comprises the old genus Tremella. Plants of this 
section are all gelatinous , hyaline , and covered with a •membrane. They are 
globose , palmate , or filiform ; and contain conferva-like filaments within. Colour 
green or purplish. They resemble Confervoidece in habit and place of growth. 
Nos //r roc. Flamentsmoniliform, constituted from coadunate globules. Fronds 
bullate, vesicular, (at length becoming flattened,) crowded with simple monili- 
form, curve-crisped filaments. 
ORDER V. LICHENES. 
Gyroph"ora. Frond foliaceous, coriaceous-cartilaginous, peltate, monophyl- 
lous, (when luxuriant, polyphyllous,) free beneath; apothecia somewhat §hield- 
form, sessile-adnate, clothed with a dark membranaceous cartilage, including a 
somewhat solid parenchymous substance; disk warty or circinal, plicate and 
margined. 
Parme'lia. Frcmd coriaceous, sub-membranaceous, flat, expanded, close- 
pressed, orbicular, stellate and lobed, or multifid-laciniate, having fibres beneath ; 
apothecia shield-form, sub-membranaceous, formed under side from the frond, 
free, with a central puncture by which it is affixed; disk concave, coloured,, 
covering the whole receptacle above, within similar, sub-cellular, and striate, 
cut round, indexed with a frond-like margin. 
Cetra'ria. Frond cartilaginous or membranaceous, ascending or expanded ; 
lobe Jaciniate, smooth and naked both sides; apothecia shield-like, obliquely 
attached to the margin of the frond, the lower free, being separated from it, 
the upper one sessile; seed bearing lamina forming the disk, coloured, plano¬ 
concave, surrounded with a frond-like indexed margin. 
Cenomy'ce. Frond crusty or cartilaginous, foliaceous, laciniate, sub-imbricate 
free, (rarely adnate ;) bearing sub-fistulous peduncles (podetia) both barren and 
fertile ; receptacles (knobs) orbicular, without margins, at length convex and 
capitate, inflated or empty beneath, terminal attached to the peduncles by their 
peripheries ; seed bearing lamina forming the receptacle above, thickish, col¬ 
oured, similar within, convex, reflexed, and attached at the periphery, invested 
beneath with the woolly integument of the frond. 
Bjeomy'ces. Frond crustaeeous, flat, expanded, adnate ; bearing soft, solid, 
fertile podetia; apothechia capitate, without margins, solid, terminal, sessile on 
the peduncles; seed bearing lamina covering the whole receptacle and adnate 
to it, convex reflexed, thickish, coloured, similar within. 
UsVnea. Frond sub-crustaeeous, teretish, branched, mostly pendulous ; cen¬ 
tral part hyaline, elastic, composed of fasicles of tubes; receptacles orbicular, 
terminal, peltate, formed wholly from the frond, covered all over with its coni¬ 
cal substance, similar, nearly of a uniform colour; its periphery destitute of 
margin, but often surrounded by a ciliate edging. 
ORDER VI- FUNGI. 
Lycoper^don. Receptacles somewhat caulescent, at length bursting at the 
top, with scaly warts or prickles scattered over its surface, especially when 
young. Seminal dust green. 
Mu'cor. Receptacle membranaceous, globose, stiped, at first watery and pel¬ 
lucid, then opake ; seeds naked, sub-cohering. Very minute and fugacious. 
Ure'do. Receptacle 0; seminal dust under the cuticle of leaves and stems, 
when ruptured it is easily brushed off; the little masses of seeds uniform, 
mostly globose. 
Agar'Acus. Destitute of a vofva at the base of the stipe, with or without the 
fing; lamellae either entire or with shorter ones intermixed, rarely simple ra¬ 
mose. Never veiny. 
Bole'tus. Pileus various; tubes and pores terete, entire. A large genus.
