During the decomposition of 250 A TEXT-BOOK OF BOTANY. leaves the acid substances are decomposed and to some extent dissipated in the form of gases. The chief agents in the decay of leaves are fungi and bacteria. A number of forms of an...imal life also contribute greatly to the decay also, as earthworms, larvae, flies and beetles and myriapods or thousand-legged worms. Coville distinguishes two kinds of leaf mold : (a) In which the leaves show a condition of imperfect decomposition, due to the development and maintenance of an acid condition, which is inimical to the growth of microorganisms of decay. Because of the resemblance of this mat or turf to bog peat in appearance, structure, and chemical composition, and be- cause it supports a type of vegetation similar to that of bog peat, it has been named UPLAND PEAT.
