Introduction to the study of fungi : their organography, classification, and distribution for the use of collectors . der the name ofPoria. The pileus is reduced to a thin stratum, mostly spreadover, and adhering closely to the matrix, the outer surfacecovered with the crowded pores. In habit the resemblance isto Corticium, but instead of a smooth horizontal hymenium itis a porous one. Normally the pores are in a single series,whilst in resupinate forms, or species, of Fomes they are thicker,firmer, and stratose. Allied to Fomes rather than to Polystictus, the genusTrametes is to be recognised chiefly by the thick obtusedissepiments of the pores,the tubes deeply sunk intothe substance of the pileus,and not stratose, and with-out the hardened crust tothe pileus. The pores arerounded and often unequal,whereas in Sclerodepsis theyare large, sometimes an-gular, with the edge acuteor toothed. Daedalea isin substance and generalappearance very likeTrametes, with the poressinuous or labyrinthiform(Fig. 53). Hcjxigonia ratherapproaches Polystictus thanTrametes, but the pores arewith firm entire Fig. 53.—Daedalea quercina. mostly large and hexagonal,Favolus differs from Hexagoniain the pores being less hexagonal, but angular and radiatingfrom the stem; most species being substipitate, and fleshyrather than rigid. In LascMa the substance is still softer,and more gelatinous, whilst the dissepiments are vein-like, I40 INTRODUCTION TO THE STUDY OF FUNGI and the pores shallower and irregular. The latter genusleads to Merulius, with its soft, waxy hymenium, the surfaceof which is reticulated with obtuse folds, forming irregularareolae, the folds sometimes rather toothed. This is possiblythe lowest and most imperfect of the Polyporei. A recentgenus, Campbdlia, is a higher development, with a pileus andstem and more distinct pits or pores. Porothelium has thehabit of Poria, but the tubes are more scattered, reduced topapillae, and at length pierced and open. Some au
