Notice their attachment to the stipe, whether free, not touching it at all; adnate, attached squarely to the stem at their anterior ends; or decur- rent, running down upon the stem for a greater or less dis- tance (Fig. 528). 394. The Hymenium. — Cut a tangential section through one side of the pileus and sketch as it appears under the lens. If a very thin cross section of one of the gills is made and placed under the microscope it will appear as in Figure 529. More highly magnified sections are shown in Figures 530, 531- The blade of the gill, called the trama, is covered on both sides by a membranous layer bearing elongated club-shaped cells set. 529-331. — Sections of a gilled mushroom : 529, through one side, showing sections of the pendent gills, g, g, (slightly magnified); 530, one of the gills more enlarged, showing the central tissue of the trama, tr, and the broad border formed by the hymenium, h\ 331, a small section of one side of a gill very much enlarged, showing the club-shaped basidia, b, b, standing at right angles to the surface, bear- ing each two small branches with a spore, s, s, at the end.
