Family 5. Pezizace^. — The apothecia of this family are saucer- 

 or cup-shaped, sessile or stalked, arising from a mycelium which is 

 found in the substratum. The peridium and hypothecium consists 

 of rounded cells and they are of fleshy, or leathery consistency. . The 

 asci, which are usually eight-spored, are separated by distinct para- 

 physes. The spores are usually hyaline. Lacknea and Peziza are 

 the most important genera. Lacknea scutellata (Fig. 58) has a 

 scarlet to vermilion-red cup, whose margin is beset with a fringe of

large brown bristles. It grows on wet sticks and logs in damp, or wet 

 places, especially at the water's edge. L. hemispJuBrica has a cup i to 4 

 cm. wide with a bluish-white to gray disk and with brownish outside 

 bristles which fringe the margin of the apothecium. It grows on much- 

 decayed wood. Peziza aurantia, which is found in the fall in woods, 

 and is edible, has a bright orange cup i to 5 cm. wide, powdery outside. 

 At first, it is cup-shaped, then saucer-shaped and irregular. It is 

 stemless, or nearly so. The spores are clear, elliptic and strongly 

 netted. A woodland form, P. coccinea, is scarlet in color and suggests 

 a wine glass in its stalked apothecium. P badia grows on the 

 ground in grassland and woodland, and is also edible. It has a
