Staining of Fungus Spores.* — Josef Schorstein has been experi- 

 menting with spores of Morchella esculenta and their reaction to stains. 

 The fungus was kept moist for a time, so that a number of spores ger- 

 minated, then after some delay they were stained. It was found that 

 the germinated spores alone had taken up the stain acid methyl-green, 

 the germinating tube turning blue. After 12 hours the tube became 

 green, and the remaining spores began to show coloration. Schorstein 

 describes the physiological conditions inducing these differences in 

 staining capacity.

Development of Lichen Apothecia.f — W. Nienburg has examined 

 the apothecia of several forms of Lichens, and draws various interesting 

 conclusions from the results of his research. He finds that in Usnea 

 several carpogonia with trichogynes are developed under the cortex, all
