Fruit-bodies of Daedalea imicolor can retain their vitality kept in 
the dark, and exposed to ordinary air at room temperatures, for at least 
eight years, and those of Schizophyllum commune for at least six years. 
These two species retain their vitality longer than any others which have 
been tested. In most species, the vitality persists only for two or three 
years and is lost in less than five. In the case of the Daedalea 
and Schizophyllum cited, the fruit-bodies revive much more slowly than 
fruit-bodies only one year old, shed a reduced number of spores, and 
become putrid relatively sooner. “It is evident that their vitality has 
become very much diminished and that shortly it will be extinguished 
altogether”. A list is given showing the length of time that certain 
Hyjnenomycetes can endure desiccation without losing their vitality. 
Experiments are described in which Schizophyllum commune retained 
its vitality after being dried and kept in vacuo for sixteen and a half 
months in the dark at ordinary room temperatures: and in which Schizo¬ 
phyllum which had already been kept for two and a half years after being 
thoroughly dried and placed in a very high vacuum was subjected to a 
temperature of —190° C for three weeks, and found to liberate spores 
when brought back to suitable conditions. The experiments seem to indicate 
that here there must be a temporary suspension of vitality.

par YAmylomyces Rouxii (Compt. Rend. Acad. Sc. 1913, 156, 
No. 12, 959—962). 
Aus Amylomyces Rouxii (= Mucor R.) kann man drei verschiedene 
Phosphor Verbindungen gewinnen: zwei organische und eine an¬ 
organische Orthophosphatverbindung. 
Die organischen Phosphorverbindungen sind als normale Bestand¬ 
teile der Pflanze zu betrachten; sie werden von der lebhaft wachsenden 
Pflanze gebildet. Die anorganischen Phosphorverbindungen entstehen da¬ 
gegen beim Altern des Pilzes als Zerfallsprodukte der organischen Phosphor¬ 
verbindungen. Die betreffenden organischen Verbindungen lassen sich 
durch ihre Löslichkeitsverhältnisse voneinander unterscheiden; die eine ist 
in Äther, die andere nur in Alcalien löslich. Lakon (Tharandt).

L’ Aspergillus fumigatus réclame, pour sporuler, la présence, dans 
le milieu de culture, de tous les éléments du liquide Raulin, en parti¬ 
culier de Mn, et à l’exclusion de Zn, dont le rôle est douteux. Au con¬ 
traire, pour Y A. niger , la sporulation n’est empêchée que par la sup¬ 
pression de K et de Mn; toutefois ce résultat reste justiciable d’expériences 
conduites avec une technique plus perfectionnée encore.
