Synopsis of the Families. 



Is ABIACEI. Receptacle clavately branched, 

 or assuming Hymenomycetous forms, com- 

 posed of filaments closely attached in their 

 whole length; spores simple, attached to 

 simple pedicels arising in all parts (fig. 349). 



STILBACEI. Receptacle wart-like or 

 elevate above, stalked below, composed of 



filaments closely packed, coherent, termi- 

 nating singly in free subgelatinous spores. 



DEMATIEI. Mycelium filamentous, spores 

 compound or simple, arising from the apices 

 of erect, solid, corticate, subopaque fila- 

 ments (fig. 346). 



MUCEDINES. Mycelium filamentous, 

 spores solitary, or crowded on articulated 

 or branched tubular and pellucid filaments 

 (figs. 344, 345), soon separating and min- 

 gling with the mycelium, or adherent in 

 chained rows. 



SEPEDONZEI. Mycelium filamentous, 

 spores usually found heaped together resting 

 on the mycelium, and apparently springing 

 out of it directly. The spores are the 

 principal element in this Order, which ap- 

 proaches Coniomycetes. 



HYP'NEA, Lamouroux. A genus of 

 Rhodymeniaceas (Florideous Algae), the 

 only British species of which, H.purpuras- 

 cens, is a common purplish pink feathered or 

 shrubby sea- weed, the lobes being cylindri- 

 cal, filiform, and cartilaginous, growing from 

 2" to 6" in height, with the filaments about 

 1'" in diam. On stones, rocks &c. between 

 tide-marks. The fructification consists of 

 coccidia, tubercles immersed in the ramuli, 

 each containing a mass of small spores ; and 

 tetraspores, immersed in the lesser branches, 

 of separate plants.

HYPNOI'DE^E. A family of Pleuro- 

 carpous Mosses of large extent. Leaves 

 with the cells prosenchymatous, dense or 

 lax, smooth or papillose. Alar cells at the 

 bases of the leaves diverse : 1 , square, flattish 

 or yentricosely impressed, pellucid or yel- 

 lowish, or fuscescent; 2, few, vesicular, 

 placed at the very base, of a delicate yellow 

 or hyaline ; 3, obsolete, scarcely any, placed 

 at the very base, fugacious, hyaline, vesi- 

 cular ; 4, many, square, in papillose leaves, 

 but mostly not very conspicuous. Leaves 

 0-5-nerved. Nerves binate, diverse : 1, 

 divergent from the base, distinct, very cal- 

 lous at the back of the leaf and prominent 

 in the form of a spine from the dorsal sur- 

 face ; 2, flattened down, scarcely callously 

 prominent ; 3, in leaves where the alar cells 

 are vesiculiform, the nerves obsolete, indi- 

 cated by a pair of very short striae, mostly 

 inconspicuous.
