species of Ghalara as figured by Saccardo* * * § and Corda,t in which the 
spores are represented as being abjointed, not at one but at various 
points within the sheath-like liyphoef as in the case of Sporoschisma 
mirabile , B. & Br.;§ Bloxamici truncata , B. & Br.$|| ThieJavia basicola , 
Zopf.jfl Aphanomyces stellatus , DBy.,** and probably, although it has 
not been possible to exa mine figures, Trullula nitidula , Sacc.tf 
When the conidiophore has reached the limit of its growth the outer 
cell wall of the tip and the portion immediately below it ceases growing 
and becomes slightly tinted olive color lik e the mycelium. The pro¬ 
toplasm contained between the last septum and the apex continues 
to grow and ruptures or absorbs the cell wall of the tip, pushing out, 
seemingly as a naked protuberance of the protoplasmic contents of the 
cell, but probably clothing itself with an extremely thin membrane, 
leaving behind the shar ply defined broken edge of the conidiophore. 
After growth has conti nued for a few minutes and the cylindrical pro¬ 
trusion has attained about the length of the diameter of the sporophore, 
a septum forms below the mouth of the sporophore and by the further 
growth of the protoplas mic contents of the mother cell the fully formed 
gonidium is pushed out from the sporophore only to be followed by a 
second spore in the same way. Fifty to sixty of these spores are fre¬ 
quently th us shoved out of a single vigorous sporophore, varying from 
one-half to one hour each in time of appearance. These hyaline conidia 
remai ned attached to each other in long chains, often doubling upon 
themselves in Van Tiegliem cell cultures and forming several rows upon 
the moist underside of the cover glass (Plate II, Fig. 1). 
It is surprising that in such a work as that by Dr. Alexander Zalewski, 
TJeber Sporenabschnur ung und Sporenabfalien bei den Pilzen, published 
in 1883,|| no mention should be made of such a striking modification of 
the author’s second type of spore formation, called S'uccedane reilieniveise

t Mr. J. B. Ellis and Dr. H. W. Harkness have kindly allowed the examination of 
Chalara acuaria, C. & E., and Chalara Irachyspora, Sacc., in which the spores are 
b orne apparently as in Chalara Ungeri, Sacc., by abjunctiou from an elongated mother 
c ell, if the term may properly be applied to such cell with power of continuous conidia 
formation.
