Fig. 17. -f-. a , a very young branch, which will give rise to a long curved 
hypha with microconidia, like that figured in b. 
Fig. 18. Branch of the mycelium with chain of microconidia. 
Fig. 19. Top of a branch with microconidia: a, top of the hypha where 
one conidium is just escaping ; c, transverse cell-wall separating a microconidium, 
not yet free from the cell-wall of the surrounding hypha; c, transverse cell-wall 
not yet quite formed. 
Fig. 20. ££- 2 -. Three apices of hyphae bearing microconidia: a , without 
conidium ; b, with a conidium just escaping ; c , with two conidia. 
Fig. 21. Three stages of development of microconidia: a, with one 
conidium ; b, three hours afterwards, with three quite developed conidia and one 
not yet ripe ; c, one hour later, the last-formed basal conidium slides out of the 
cell-wall of the hypha like a microconidium. 
Fig. 22. A group of macro- and microconidia of different size. 
Figs. 23-32. Melanconium (Sacchari ?). 
Fig. 23. - 2 -P-. Stylospores germinating after one day. 
Fig. 24. -j-. Part of a mycelium developed in three days from the stylospore c 
in a hanging-drop of wine-must. 
Fig. 25. -j- 2 -. The same as Fig. 24, but three days later. 
Figs. 26, 27, 28. -®-. Mycelium with large black conidia. 
Figs. 29, 30. -S-^- 2 -. Mycelium with large black conidia. 
Fig. 31. -i- 2 -. Mycelium with branches developing conidia. 
Fig. 32. ^f- 2 -. Mycelium with chlamydospore g.
