334 FaulL — The Cytology of 
stain bright red and the linin network blue. The chromatin is sometimes 
in shapeless masses, but most frequently in longer or shorter threads 
or granules (Fig. i). Whether or not there is a definite number I cannot 
say. Now and then only two chromatic elements can be counted ; at other 
times four, while in other instances there seem to be more. Nor can 
I satisfy myself that they bear any relation to a central body, or, indeed, 
that a central body is a constant concomitant of the nucleus. It may be. 
Not seldom a granule that might be interpreted as such lies in contact with 
the nuclear membrane in the cells of the appendages, but as there are other 
red-staining granules in the cytoplasm it is difficult to say just what 
this particular one really is. 
Mitotic figures in the hyphae of several Ascomycetes have been 
observed by a number of cytologists, excellent illustrations, for example, 
being given by Fraser (’08) for Humaria , and Schlirhoff ('07) for Penicillium. 
Faull (’05) and Dangeard (’07) have noted them in the spores. 
The cytoplasm is finely granular or reticulate, but usually in the larger 
cells it is of a coarse spongy or reticulate structure. Oil bodies in L. chaeto - 
phora and L. Gyrinidarum are rare, but abundant quite highly refractive 
granular inclusions are of common occurrence. They may be small or 
quite large, and often regularly curved. Various sizes are shown in Figs. 3- 
6. They appear to be formed in the meshes or cavities of the protoplasm. 
The nature of these bodies was not determined. They make their appear- 
ance as the plant approaches maturity and do not show any especial 
affinity for the stains that were employed, though taking up the safranin 
and gentian violet to a limited extent, in contrast to the cytoplasm, which 
has a greater affinity for the orange G. Thaxter (’96) records an interesting 
fact in this connexion, namely, * that the contents of the living cells consist 
of rather dense granular protoplasm, in which, as a rule, certain highly 
refractive spherical oily masses are conspicuous. In some instances these 
masses are few in number, one or more of them being often very large 
(PL V, Figs. 4 and 5), while again they may be more numerous and uniform 
in size, completely filling the cells, as in the case of Laboulbenia Harpali , 
L. Philonthi , and many others.’ Whether or not the bodies I have 
described are to be identified as the smaller ones detected by Thaxter 
I cannot say, but it seems not improbable that they are the same. 
There is still another feature to be mentioned, to which reference 
has already been made, that is, the presence of protoplasmic strands running 
out from the pits in the septa and from the nuclei. These phenomena have 
been repeatedly observed. Fig. 20 illustrates a case in point. The strands 
passing out from a pit in one of the cells intersect those coming from the 
pit in the opposite septum. The strands are slightly darker, as if of denser 
substance than the rest of the cytoplasm, but at the points of intersection 
are several brightly red-staining granules, such as are to be found in the
