 seberry-Mildew poisonous?]. (Medd. fra Foreningen tilSvam- 

 pekundskabens Fremme. I. 108—111. K0benhavn, 1915.) 



Against the supposition that gooseberry, attacked by the mil- 

 dew, Sphaerotheca mors uvae, should be dangerously poisonous for 

 man, the author tries to prove the improbability hereof.

The house-fly pest {Empusa muscae) has been kept in culture 

 on living flies for two months during Nov. and Dec. The time of 

 incubation was 7 days. The author did not succeed in growing the 

 fungus on artificial substrata. It is thought that the pest might be 

 useful in the control of the house-fly, and a scheme is mapped out.

1. Les faux balais de sorciere de l'Arbousier. — Les pousses 

 envahies par Exobasidium Unedonis n. sp. forment dfes le mois de 

 fevrier, dans les forets d'Algerie, des touffes d'un vert päle rou- 

 geätre. Ce n'est pas un vrai balai de sorciere, car les pousses sont 

 en nombre normal et ne se ramifient pas; elles sont seulement de- 

 formees et plus precoces que les pousses normales. Les jeunes 

 pousses envahies meurent avant que les pousses saines aient pris 

 leur dimension definitive. Toutefois elles ne tombent qu'au cours 

 de l'hiver suivant.
