The pre- H YMENOM YCE TES 127 ceding chapter having prepared us for the general attributes ofthe order, we may proceed to indicate the six groups into whichthe genera naturally fall. Four of these have the hymeniuinnormally inferior, in the other two either superior or on all four first are the Agaricini, Pohjporci, Hyclnci, Thdcpliorci,and the two latter Clavariei and Trcmellini. The Agaricini are pre-eminently soft, fleshy, putrescentFungi, of the mushroom type, in which the inferior hymenium,or spore-bearing surface, is spread over folds, or gills, which ^. ^\f^. Fig. 49.—Agaric. A, young state ; B, mature ; C, section, radiate from a central stem to the circumference of a pileus orcap. In the typical form there is a floccose mycelium ofdelicate threads, surmounted by a stem, more or less developed,and crowned by a hood or cap of umbrella-like form, with gillson the under surface. In the earliest condition the form isnearly globose, enclosed like an egg within a thin shell ormembrane. As it progresses in growth the egg-shaped bodysplits round the centre, the upper hemispherical portion beingcarried upwards by a quick-growing stem, forming the cap, thelower half remaining behind to constitute the base. At themargin of the pileus the jagged remains of the fissured mem-brane often adhere for some time, and in like manner there 128 INTRODUCTION TO THE STUDY OF FUNGI may be traces of the fissure on the basal portion.
