194 Barker .— The Morphology and Development of 
formation of transverse septa. The cell at the apex of the 
ascogenous hypha he called the terminal cell, the middle cell 
the sporangium, and the lower cell the pedicel. The latter 
proceeded to put out branches, which grew around the 
sporangium, completely enveloping it. At the same time, 
the sporangium itself was continually swelling up, reaching 
in some cases a diameter of 75 /x. The terminal cell and the 
first investing hypha were soon lost sight of, owing to the 
development of the other investing hyphae. During the en- 
largement of the sporangium its wall thickened and its proto-' 
plasmic contents passed through several striking changes. 
In the young sporangium the protoplasm contained several 
large vacuoles. These divided again and again until the 
protoplasm possessed a foam-like structure. Later it became 
very opaque, the vacuoles at the same time becoming ex- 
ceedingly small, so that the interior of the sporangium could 
not be clearly seen. In the end the contents divided up into 
a number of spores. The exact moment of the division 
could not be discovered. While usually the whole of the 
sporangium was filled with spores, instances were occasionally 
met with where spores were only to be found in one portion 
of the sporangium, the remainder being filled with vacuolated 
protoplasm. When the surface of the mass of spores was 
carefully examined, no interstitial material was found between 
the spores, the latter presenting an angular appearance. The 
number of spores was variable, some sporangia containing 
only 6-10, while others contained from 150 to 500. When 
the spores were first liberated they retained their angular 
appearance, but soon assumed an oval shape. In size they 
were about 5-6*5 jot. Conidia were also produced soon after 
the formation of the perithecia. They resembled those 
described by the earlier authors. With regard to the 
systematic position of the fungus, Went, on Van Tieghem’s 
authority, in the absence of the necessary literature placed it 
in the genus Monascus. He considered also that this genus 
ought to be placed among the Hemiasci, showing in par- 
ticular much resemblance to Thelebolus . He also discussed
