EXPLANATION OF FIGURES IN PLATES 
XII and XIII. 
Illustrating Mr. Barker’s paper on Monascus. 
Fig. 1, a-e. Successive stages in the germination of a conidium. x 400. 
Fig. 2, a-h. Successive stages in the formation of an archicarp. x 800. 
Fig. 3, a, b. Two periods in the development of an archicarp, showing the 
branching of the antheridial branch and the formation of a conidium by it. x 650. 
Fig. 4. Intercalary formation of an archicarp. x 650. 
Fig. 5. An ascogonium spirally curved around an antheridium. x 800. 
Fig. <5. A conidium functioning as an antheridial branch, x 650. 
Fig. 7. Archicarp formation at the base of a chain of conidia, the lowest 01 
which behaves as an antheridial cell, x 650. 
Fig. 8. Showing point of fusion between the ascogonium and the antheridial 
branch at some distance behind the apex of the former, x 800. 
Fig. 9. Showing fusion between the ascogonium and the antheridial branch, in 
which the papilla developed from the latter is conspicuous, x 3000. 
Fig. 10. Formation of papilla on the antheridial branch beyond the apex of the 
ascogonium, the latter having ceased to grow, x 650. 
Fig. 11, a-d. Development of investing hyphae. Successive stages, x 1000. 
Fig. 12. Formation of auxiliary investing hyphae. x 1500. 
Fig* I 3> ct~c. Successive stages in the development of an ascocarp, showing the 
origin and development of the 4 internal ’ hyphae and asci. x 1000. 
Fig. 14. A branch bearing an ascocarp and clasping hyphae. x 800. 
Fig. 15, a-c. Nuclear structures in archicarps. (a) Fusion between the asco- 
gonium and antheridium doubtful : both organs crowded with nuclei, especially at 
the place where fusion occurs, (b) A nucleus occupying the canal between the 
ascogonium and antheridium. Central cell cut off and filled with nuclei. Nuclei 
in male branch comparatively few with sharp outlines, (c) Aggregation of nuclei 
in the centre of the swelling central cell, x 1 200. 
Fig. 16. Section through young ascocarp showing comparatively large central 
cell surrounded completely by investing hyphae. x 1000.
