The multitudinous forms which fungi assume, the differences of substance, and variability in size, render a somewhat detailed account of the modes adopted for their collection and preservation necessary. The habitats of the various groups have already been indicated, so that there need be no difficulty in selecting the most suitable spots, and as to the period of the year, this will be determined by the class of objects sought. Although it may be said that no time, except when the ground is covered with snow, is entirely barren of fungi, yet there are periods more prolific than others.[A] Fleshy fungi, such as the _Hymenomycetes_, are most common from September until the frosts set in, whereas many microscopic species may be found in early spring, and increase in number until the autumn.
