Fig. 90. — Sporobolomyces roseus. Production of three spores successively 

 on one and the same sterigma, represented in lateral view semi- 

 diagrammatieally. The yeast cell is on malt-agar. Nos. 1-8, stages 

 in the development of the sterigma and the first spore ; nos. 9-12, 

 stages in the development of the second spore ; and nos. 13-16, 

 stages in the development of the third spore. Drop-excretion at the 

 spore-hilum prior to spore-discharge is shown : for the first spore at 

 nos. 6 and 7 ; for the second spore at no. 1 1 ; and for the third spore 

 at no. 15. Nos. 8, 12, and 1G show the discharge of the first, second, 

 and third spores respectively. The drop and the spore are shot away 

 together. Drawn by A. H. R. Buller and Ruth Macrae. Magnifi-
