„investing hyphae, the development of which seems to be 

 „called forth by the act of fertilization, the ascocarp is 

 „produced. 



4. „The central cell swells enormously the investing hy- 

 „phae keeping pace with it. 



5. „The next step in the development consists in the 

 „formation of ascogenous hyphae from the central cell. 

 „It has not been possible to observe the earliest formation 

 „of thèse hyphae, owing among other things to difficulties 

 „in distinguishing them from hyphae. Nevertheless at a 

 „very young stage they hâve been observed as shortcoi- 

 „led, comparatively stout hyphae, situated in a kind of 

 „little nest or dépression in the side of the central cell. 



6. „It (the dépression) soon begins to increase in size, 

 „being ail the whiie completely filled with closely entwi- 

 „ned hyphae. 



7. „The ascogenous hyphae eventually produce small 

 „spherical eight-spored asci. 



8. „The asci are very thin-walled, and soon break down, 

 „liberating the spores into the cavity of the nest and at 

 „the same time the ascogenous hyphae also degenerate, 

 „so that the ripe ascocarp is filled, with a large number 

 „of spores, lying free in its interior amid a mass of mu- 

 „cilaginous substance, produced by the degeneration of the 

 „other structures." 



Auf Seite 196 — 199 1. c. folgt jetzt eine Erôrterung ûber 

 die sehr nahe Verwandtschaft von M. purpureiis Went, 

 und Barkers eigenen Material. Die ganzlich verschiedene 

 Resultate werden fehlcrhaften Beobachtungen Wents zu- 

 geschrieben wie wohl Barker M. purpureus Went nicht 

 gesehen hatte. 



Es lohnt sich einige Worte, in denen Wents und Bar- 

 kers Beobachtungen verglichen werden zu zitiren: „But 

 „we hâve seen that the apparent vacuolization is really 

 „due to the formation of hyphae branches from the „spo-
