Schaeffer, I would suggest that these are instances of increase from ad- 

 hesion. During the development of the ovules of the higher plants, 

 adhesion frequently takes place so as to produce a double seed, or a 

 better illustration will be found in the instances of proliferous flowers, 

 as seen in the common daisy called hen-and-chickens. 



It is then probable that such instances of multiplication in fungi 

 arise from the same cause, and that during their early development 

 two or more spores are developed under the same volva, and the 

 smaller fungi are nourished through the means of the larger one, just 

 as the smaller flowers of the daisy grow on the larger one. 



In submitting these remarks to the attention of the Microscopical 

 Society, I do it with the hope of drawing attention to an interesting 

 department of inquiry, and not at all with the feeling that I have 

 given that attention to the subject which its interest and importance 

 demand.
