VIII. FUNGI. 
This suborder is distinguished by the relative predominance of the reproductive bodies, 
which are very fugacious and soil the hand. It contains many obscure and most curious 
plauts, whose development and organization have taxed the skill and patience of the most 
eminent naturalists. Some species present different forms, arising from different forms of 
spore ; some are supposed to originate infectious diseases in the animal kingdom ; others 
attack and destroy living plants. 
Tribe XI. Sphaeronemei. Perithecium more or less distinct. 
38. Leptostroma. Perithecium thin, falling off by a transverse rupture. 
39. Phoma. Perithecium puuctiform or pustular, with a minute orifice. Spores minute, 
simple. 
40. Hendersonia. Perithecium subglobose. Spores 2-multiseptate. 
41. Archersonia. Perithecium fleshy, lobed, multicellular. Spores simple or septate. 
42. Phlyct.ena. Perithecium spurious ; spores very slender, on short sporophores. 
43. Pilidium. Perithecium flat, shield-like, smooth, variously ruptured. Spores linear, 
sessile. 
44. Asteroma. Perithecia arising from creeping filaments, flat, with no determinate 
orifice. 
Tribe XII. Torulacei. Perithecium altogether wanting. Spores compound , monili- 
form or arising from, repeated division , rarely reduced to a single cell. 
45. Gymnosporium. Spores superficial, conglobate. 
Tribe XIII. Pucciniaei. Parasitic on living plants. Peridium 0. Spores producing 
secondary spores in germination , usually ohlong and septate. 
46. Puccinia. Spores naked, 1-septate, on a distinct peduncle. 
47- Uredo. Spores sessile, each contained in a cavity of a multicellular stroma. 
48. Uromyces. Spores stalked, each contained in a cavity of a multicellular stroma. 
49. Ustilago. Spores deep-seated, simple, on delicate threads, or breaking up into a 
powdery mass. 
Tribe XIV. .fficidiacei. Peridium distinctly cellular. Mycelium traversing the tissues 
of living plants. 
50. jEcidium. Peridium bursting open. Spores concatenate. 
Suborder IV. Hyphomycetes.— Filamentous or floccose Fungi. Fila- 
ments naked, simple or branched, free or united below so as to form a distinct 
stem with free branches. Spores terminating the filaments. 
Most of the species of this vast tribe come under the common term of moulds, whose 
ravages no animal or vegetable matter escapes. Coincident with their attack a chemical 
change takes place in the substance attacked, known as fermentation. They are developed 
with extreme rapidity, and are often poisonous. The various mildews of the Vine, Hop, and 
silkworm belong here, as do the potato disease, and o'idium of the grape. 
Tribe XV. Stilbacei. Stem or stroma compound. Spores collected into a globose head, 
usually terminating a distinct stalk, sub gelatinous, diffluent. 
51. Stilbum. Stem firm, long. Head globose, deciduous. Spores small, involved in 
gluten. 
52. Epicoccum. Head subglobose, studded with large spores. 
Tribe XVI. Dematiei. Filaments free, more or less corticated and carbonized. Spores 
often compound and cellular. 
53. (Edemium. Filaments free, dark, flexuose, with reticulate large spores on their 
sides. 
54. Macrosforium. Filaments slender, evanescent. Spores erect, stipitate, multi- 
septate.
