der-side from the frond, free, with a central puncture hy which it is af- 
fixed : seed-bearing lamina forming the disk, concave, coloured, covering 
the whole receptacle above, within similar, sub-cellular and striate, cut 
round, inflexed with a frond-like margin. 57. 2. 
Cetra ria. Frond cartilaginous or membranaceous, ascending or ex- 
panded ; lobe-laciniate, smooth and naked both sides ; receptacles (tar- 
gets) shield-like obliquely attched 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, within similar or cellular-striate, 
surrounded with a frond-like inflexed margin. 57. 2. 
Cexomy'ce. Ffond 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 attach- 
ed to the peduncles by their peripheries: seed-bearing lamina forming the 
receptacle above thickish, coloured, similar within, convex, reflexed and 
attached at the periphery, invested beneath with the woolly integument 
of the frtmd. 57. 2. 
Bsemy'cf.s. Frond crustaceous, flat, expanded, adnate ; bearing soft, 
solid, fertile peduncles {podetia :) receptacles (knobs) 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. 57. 2. 
Us"iVEA. Frond sub-crustaceous, teretish, branched, mostly pendulous ; 
central part hyaline, elastic composed of fascicles of tubes : receptacles 
orbicular, terminal, peltate, formed wholly from the frond, covered all over 
with its cortical substance, similar, nearly of an uniform colour ; its peri- 
phery destitute of margin, but often surrounded by a ciliate edging. 57. 2. 
Order 6 . Fungi. 
Lycoper"doS. Receptacle somewhat caulescent, at length bursting at 
the top, with scaly warts or prickles scattered over its surface, especially 
when young. Seminal dust green. 58. 1. 
Mucor. Receptacle membranaceous, globose, stiped, at first watery 
and pellucid, then opake ; seeds naked, sub-cohering. Very minute and 
fugacious. 58. 1. 
Ure'do. Receptacle none ; seminal dust under the cuticle of leaves 
and stems, when ruptured it is easily brushed off; the little masses of seeds 
uniform, mostly globose. 58. 1. 
Agar 'icus. Destitute of a volva at the base of the stipe, with or with- 
out the ring ; lamellae either entire or with shorter ones intermixed, rare- 
ly simply ramose. Never veiny. A vast genus. Persoon describes 447 
species, which occupy one third of his work on Fungi. 58. 1. 
Bole tus. Pileus various ; tubes and pores terete, entire. A large 
genus. Persoon describes 83 species. 58. 1.
