(Auersw), Lewis (1911) about the Pleurage Zygospora, Dangeard 

 (1907) — Podospora hirsuta (sp. nov.), Wolf (1912) about Podospora 

 anserina (Wint.) and Woronin (1869) about Podospoi-a fimiseda 

 (Ces et de Xot, Sordaria fimiseda Ces et de Xot, Bombardia fimi- 

 seda Kirstein) ^). 



Zukal (1889) states that the perithecium of the Sordaria Wies- 

 neri is formed from the entwining of several side branches of the 

 cells of the mycelium, wliicli originate on different hyphae. This 

 form possesses no sexual cells. 



Gilkinet (1876) in his investigations notes, that the Sordaria fimi- 

 4îola has quite developed male (pollinodium) as well as female (car- 

 pogonium) sexual cells. These look like threads coiled in a spiral. 

 He thinks the top of these threads fuse and from the carpogonium 

 fertihsed in such manner is generated the fruit body. The same is 

 noted by Nichols (1896) in a similar form. This author denotes 

 that the antheridia are not always developed, although it appears, 

 this does not hinder the further development of the ascogonia and 

 the formation of the ascogenous hyphae with asci. 



Dangeard (1907) quite denies the presence of antheridia in the 

 Sordaria fimicola and in other species, Avhich he has investigated. 

 As to the structure of the ascogonia, he notes the same spiral 

 coiled thread, as described by the two above mentioned investiga- 

 tors, not only in the Sordaria fimicola, but also in the Hypocopra 

 merdaria and Podospora hirsuta. The origin of the ascogenous hy- 

 phae, forming asci, is not cleared up in the latter specia. But Dan- 

 geard considers fully established the connection between the asco- 

 gonium and the ascogenous hyphae in S. fimicola -) and notes 

 that the same connection must probably exist in the H. merdaria. 



The development of Sordaria macrospora and Sporormia inter- 

 medie, as stated by the same author, is somewhat different. By the 

 first species the formation, wiiich he takes for an ascogonium, looks 

 like a long straight thread, which is divided by transversal walls 



1) We must also note Griffiths' study. Xot having the same лув can only 

 indicate that it can be found in the 3Iem. of Torrey Bot. Club XI, 1 — 134 p. 

 ] — 19 plate. 1901. The North American Sordariaceae. 



2) This connection is not shoAvn on the drawing given by the author (Plate 

 LXXIV, Fig. 5). Small cells with dense contents simply lie next to the ascoge- 

 nous cells and are no луЬеге joined with flie same.
