EXPLANATION OF PLATES XXVIII & 1.:^^.— Continued. 



Fig. 16.— Vertical section through a nearly ripe " fruit-body " about the 

 median line ; several asci are far advanced, others and younger ones are 

 being produced among the delicate filaments. Zeiss E. 



Fig. 17. — Very thin median vertical section through a fruit-body at a 

 stage somewhat younger than fig. 10 ; among the hyphae filling up the 

 space beneath is the young coil of ascogeuous hyphee, the cells of which 

 are filled with fine grained protoplasm. Zeiss J. 



Fig. is. — Ascogenous hyphfe bearing asci in various stages ; from vertical 

 sections about the stage represented in fig. 16. Zeiss J. 



Fig. 19.— Filaments and young ascogenous hyphse obtained from the 

 inside of a fruit-body by dissection; about the same age as fig. 16. 

 Zeiss J. 



Fig. 20. — Portions of the cellular disc bearing fine branched filaments 

 which radiate into the cavity ; about the same stage as the last. Zeiss J. 



Fig. 21. — Ascogenous hyphse and young asci obtained from the inside of 

 a fruit-body at the same stage. In one ascus the protoplasm has already 

 begun to divide ; contents contracted by glycerine. Zeiss J. 



Fig. 22. — Portion of vertical section through a young fruit-body, 

 showing relations of the parts figured ; a young ascus has arisen from the 

 mass on the floor. Zeiss J. 



Fig. 23. — An ascus somewhat more advanced than in fig. 22 ; the pro- 

 toplasm has partially divided into four. Zeiss J. 



Fig. 21. — Similar preparations in glycerine ; in one case the protoplasm, 

 mostly divided into a tetrad, is pressed out from the young ascus. 



Fig. 25. — Portion of the mycelium on which two tufts of the " sporidia " 

 bearing filaments have arisen ; the filaments and " sporidia " are enveloped 

 in jelly. Zeiss D. 



Fig. 26. — Vertical sections through the points of origin of the tufts ; 

 the curved spore-like bodies are produced from the ends of the filaments. 

 Zeiss D. 



Fig. 27. — " Sporidia," and the filaments producing them more highly 

 magnified. Zeiss J. 



Fig. 2S. — Portion of mycelium with two of the tufts. Zeiss J. 



Fig. 29. — One of the tufts with numerous minute granules embedded in 

 the jelly. Zeiss E. 



Figs. 30 and 31. — Similar tufts from the lateral lobes which produce the 

 discs ; here, as in figs. 28 and 29, no " sporidia " are as yet abstricted off. 



Fig. 32. — Larger branches of the mycelium, the cells of which retain 

 their pale colour, and separate as toruloid individuals. Zeiss J.
