io Kingo Miyabe . — On the Life-history of 
growing paraphyses seemed to be dissolved away, their places 
being occupied at once by the latter. 
This internal change was accompanied by the general 
growth of the perithecium. The growth was especially active 
in the upper portion, which was prolonged into a short blunt 
beak. The bundle of paraphyses grew into the beak, forming 
a comparatively broad canal, and ceased to grow when it 
reached the external layer of the obtuse tip, on which usually 
more than one short papilla was found. 
The paraphyses were filiform, septate, and simple, or very 
rarely branched. They were then copiously filled with 
glycogen and fatty matters. The perithecia ceased to grow 
in size when the paraphyses in their interior had reached 
their full development. All subsequent changes in the interior 
attending the growth of asci produced little or no effect on 
the external configuration of the perithecium. 
About two weeks after the sowing, a large number of 
asci began to grow among the rows of paraphyses. The asci 
were formed as branches on some of those cells from which 
the paraphyses had sprung (Figs, io e and J2 A). They were 
at first somewhat club-shaped, and were full of colourless gran- 
ular protoplasm free from glycogen. The growth of the asci 
generally began to take place when the bundle of paraphyses 
had reached its full size. I have observed a few cases, how- 
ever, in which the asci had grown to about the length of the 
paraphyses, when the latter were still at about two-thirds of 
their growth. 
In an ascus which had attained the length of about 70m. mm., 
that is about one-half its full size, a globular nucleus was 
observed in its upper portion (Fig. 1 3 A). In one which had 
progressed a little further, eight spore-primordia made their 
appearance. When they were surrounded by a cell-wall, they 
were first divided into two by a transverse septum at the 
middle, then into four by two septa parallel to the first one 
(Fig. 12 B). At this stage, the spores were colourless and 
spindle-shaped ; and the ascus was still copiously filled with 
granular colourless protoplasm. Before any further division
