200 Barker .— The Morphology and Development of 
the stages figured by Went in the latter’s Figs. 20 and 22. 
Uyeda’s Fig. 9 represents a section through a developing 
perithecium, showing a large 'sporangium’ surrounded by 
a wall of hyphae. The S sporangium ’ is undivided and 
filled with granular protoplasm. Apart from any question 
as to whether any ‘ internal hyphae ’ have been overlooked 
in this preparation, it may represent the stage shown in 
Fig. 19 of this paper, or it may represent a section through 
an older perithecium, in which none of the ‘ internal hyphae ’ 
have been included, a portion of the swollen central cell with 
its investment of hyphae being merely shown. Fig. 10 of this 
observer represents a section through a perithecium, similar 
in size to the preceding, but having the ‘ sporangium ’ com- 
pletely divided into more or less angular areas. This, I 
suppose, represents the division of the protoplasm of the 
sporangium into spores, and may correspond to the stage which 
I have described above, where the ripe spores freed from the 
degenerated asci are lying within the perithecium and appear 
to be arranged in angular areas: but, judging from the figure, 
it probably represents the stage where the perithecium is 
entirely filled with dense entwined hyphae, shortly before the 
formation of the asci. There is then nothing in Uyeda’s paper 
to lead one to suppose that the ‘ Beni-koji ’ fungus differs in 
any way from M. purpureus , and thus from the - Samsu’ fungus, 
in the nature and method of development of its perithecia. 
Considering now Harz’s paper on Physomyces heterosporus , 
seeing how closely his account of the structure and develop- 
ment of the ‘ sporangia 5 corresponds with the accounts given 
by Went and Uyeda for M. purpureus , it seems hardly 
necessary here to recount in detail the reasons for supposing 
that he was really dealing with a form of Monascus. It is true 
that he did not describe the earliest stages of perithecial 
formation in much detail, and that consequently no com- 
parisons can be made as to the method of division of the 
ascogonial filament. But he stated that the earliest stages 
were represented by the formation of two or three small 
hyphae at the apex of a branch of the mycelium, and that
