by fusion of the protoplasmic contents of the beaks. A few 

 hours after fusion the protoplasm contracts from the walls, and 

 small spherical masses are formed, which eventually become 

 spores. 



The probability of this being a sexual act is supported by 

 the presence of a deeply stained body presumably a nucleus, irr 

 the beak, of each conjugating cell. After conjugation these two 

 bodies fuse, the fused mass afterwards dividing, one portion 

 passing into each cell, where it eventually breaks up into a 

 number of bodies round which the spores are formed. This 

 conjugating yeast constitutes the type of a new genus called 

 Zygo-saccharomyces. ____ G. Massee (Kew).

I. Cercosporella Narcissi n. sp. 



Alba aut albida, 100 — 150 ft alta, effusa, fasciculata, amphigena^. 

 in partibus foliorum mortefactis ochraceis aut ochraceo-fuscis parasitans, 

 sporalis elongatis, inverse cylindrico-clavatis. 



Hyphae conidiferae fasciculatae, breves, 20 ^ circiter longae, 2 — 3 

 crassae, hyalinae, continuae, intus granulosae, cylindricae sed ad apicem 

 undulosae vix attenuatae. Sporulae majores, 50 — ISO,*/ longae, 4— 5 latae^ 

 3 — 8 septalae, hyalinae, intus granulosae praecipue ad basin, ad apicem 

 saepius attenuatae, sed etiam breviores, cylindricae. 



Ad folia Narcissi poetici culti quae execat; Montmorency, 1898 et 

 1899. Etiam Peronnas prope Bourg (Ain) unde misit Dom. Clerc. 



Ce parasite mortifie les feuilles ä la fa9on du Botrytis cinerea 

 mais il est peu prejudiciable parce qu'il ne se montre guere qu'apres la 

 floraison. 



II. Scopiilaria Clerciana n. sp. 



Hyphae fertiles gregariae, erectae, crassae, polyseptatae, minutissime^ 

 verruculosae; simplices, 0,30 mm — 0,50 mm altae, 25 ,« crassae, pallidae 

 et vix fuscescentes, ad apicem conoideae et ramis congestis oblongo- 

 cylindricis, medio uniseptatis, verticillatis, ad apicem 3 — 4 divisis, ramulis 

 tenerrimis longe acutis, etiam uniseptatis, articulos 3—5 Ultimos 

 hypharum tegentibus et scopulam minutissimam formantibus. Hae sco- 

 pulae muco agglutinatae capitulum rotundum album sporarum penetrant 

 et sustinent. Sporae albae, ellipticae, intus guttulis minutis repletae 

 aut granulosae, 7 — 8 // longae, 4 crassae, ad apices ramulorum primo 

 gignuntur.

II n'existe aucune relation entre la production de l'acide 

 succinique et de laglyc^rine; les deux varient, independamment 

 l'une de l'autre, avec les conditions de l'exp^rience (influenae 

 du Sucre, de la matifere azot^e, des acides, de la temperature) 

 et avec la levure employee (levure de vin et levure de sucre 

 de lait).
