Though there are exceptions to these rules, the beginner at collecting fungi for the table should not take immature fungi whose true character cannot be told. Reject fungi with enveloping cups at the base of the stem. Reject brightly colored fungi. Do not take fungi with gills white at maturity. Do not lake toadstools that ha\e tubes or pores on the under side. Do not take fungi with a milky juice. Before eating the fungi the novice should show them to an expert collector. Puff-balls are globu- lar fungi whose spores develop inside the mass and escape when the ball ruptures. Some attain a large size, a foot or more in diameter. One form has a thin rind which bursts at the lop and, when pressed, emits a cloud of fine spores. Puff- balls are found in fields and pastures and are edible in the white stage. Some fungi form shelf-like projections on trees and fallen logs, and on slumps. Some of these have gills (shelf agarics); others have myriads of small pores or tubes in which the spores form (Polypores'). Others again have numerous fine teeth on the under side on which the spores form (as in Hvdniim of the hedgehog fungi); in others the spores are borne upon branching surfaces, as in the coral-like Clavaria. Some fungi spread out on stumps and logs in gelatinous Fig. 171.
