Extract

So far as I am aware, the manner of the dehiscence of the perithecium of Sphaerotheca mors-uvae has not hitherto been described. Although in the main features the process of dehiscence is very similar to that which I have described for Erysiphe Graminis and for Sphaerotheca Humuli, some new points of interest have been observed.

Page 189 note 1 To secure as far as possible uniformity of the material as regards degree of maturity, every patch of mycelium (with its perithecia) taken from the shoots was divided into three portions, and one piece placed in each Petri dish. This was easy to do, as the patches were from 5 to 8 mm. long. The total size of the material placed in each Petri dish was 1 × 5 cm.
