Fig. 17. Section through an ascocarp of the same age with the central cell not 
completely in view, x 1000. 
Fig. 18. Section through a slightly older ascocarp, a small part only of the 
central cell being included, x 1000. 
Fig. 19. Section through an ascocarp of the same age, showing a large 
undivided central cell, x 1000. 
Fig. 20. Similar section through a rather older ascocarp, showing a beak -like 
protuberance of the central cell, x 1000. 
Fig. 21. Section through an ascocarp showing a large central cell with a small 
nest of ascogenous hyphae at one point of its surface, x 1000. 
Figs. 22-24. Similar sections, showing varying position of the nest of ascogenous 
hyphae. x 1000. 
Fig. 25. Section through an ascocarp, showing the central cell as a complete 
ring around the ascogenous hyphae. X 1000. 
Figs. 26-31. Various stages in the further development of the ascocarp, showing 
the increasing complexity of the internal ascogenous hyphae and variations in the 
extent of the development of the central cell, x 1000. 
Fig. 32. Section through an ascocarp containing ripe asci. No trace of the 
central cell, which has degenerated, x 1000. 
Fig. 33. Section through a ripe ascocarp, showing spores lying free within the 
sporangium-like fructification, x 500. 
Fig. 34. Surface view of a young ascocarp, showing a conspicuous hyphal-like 
protuberance of the central cell. The investing hyphae are omitted with the 
exception of the cross sections around the central cell, x 1000. 
Figs. 1-14 were drawn from living material observed in hanging-drop cultures 
of beer-wort agar; Figs. 15-34 from fixed and stained material. Fig. 15, a , b, c, 
stained by the haematoxylin-iron-alum method, and Figs. 16-34 with safranin.
