gillus Orysae can produce comparatively much tryptophane. Conse- 

 quently several alcoholic drinks, brewed from raw material, in 

 which Koji, a steamed rice upon which the mycelium of ^s^^r^/Z/ws 

 Orysae has been developed, is used, contain tryptophane. The quan- 

 tity of tryptophane produced differs according to the varieties of 

 Asp. Orysae; the Optimum temperature for its formation being 55°, 

 the crilical temperature which destroys the enzyme 68 — 70°. Other 

 mould fungi {Aspergillus albus, A. nidulans, A. ßavus, A.luchuensis, 

 A. Wentii, A. melleus, Dematium pullans, Penicülutn glaucurn) and 

 many Yeasts formed tryptophane also; most of these, as Sake-yeasts 

 and socalled ageing yeast [Willia anomala) are able to assimilate the 

 substance afterwards, while lactic acid bacilli seem not to posess 

 the power of assimilation. M. J. Sirks (Haarlem).

Gelegentlich der an verschiedenen Arten Böhmens (im Süden 

 und Osten) beobachteten Erkrankung der Kleearten (Krebskrankheit 

 des Klee) bespricht Autor die Morphologie und Oekologie des Erregers 

 dieser Krankheit, der Sclerotinia trifolioruni Eriks. Autor hat sie 

 nicht nur an Kleearten (z. B. auch auf Trifolium pannonicurn) , son- 

 dern auch an anderen Pflanzen, wie z. ß. am Lotus corniculatus und 

 L. uliginosus konstatieren können. Jar. Stuchh'k (Zürich).

Discusses the connection of the spheres of Entoloma microcar- 

 piim with those of Aegerita Duthiei the well-known termite 

 fungus. The facts available tend to show that the Entoloma is not 

 connected with Aegerita and that it is only accidentally presenl on 

 old termite nests. A. D. Cotton.

 b a r k and Nectria cancri nova species. (Ann. Jard. bot. Bui- 

 tenzorg. XXVII. p. 59—64. with 4 pl. 1913.) 



In his researches about cacao-canker in Java, the Author ob- 

 tained 15 strains of Fusarium, being present as saprophytes in 

 diseased bark. Six of these belonged, as indicated by spores and 

 colour of cultures to F. {Spicariä) colorans de Jonge; the other 9 to 

 F. theobromae Appel et Strunk. From these nine strains 5 always 

 gave, when cultivated on wood (cacao-twigs), not on rice or agar, 

 perithecia, also in pure cultures, derived from one isolated asco- 

 spore; the perithecia appeared to belong to the genus Nectria, but 

 it could not be identified with one of the existing species; a new 

 species Nectria cancri n. sp. therefore being created. Description 

 and tigures of this new species are given.
