SUPPLEMENTARY REMARKS ON BUD-, MOULD-, AND AXIMAL-FUNGI.
BUD-FUNGI.

Bud-fungi (yeast-fiingi, yeast, Saccliaromycetes,Bla8tomycetes,
etc.) are microscopically small, mostly spherical, oval or cylin-
drical vegetable cells, witli membrane and protoplasm (Fig. 123).
The size of the cells varies considerably in the diflterent kinds,
from 2.5// in thickness and 5// in length in Saccharomyces exig-
uus, to bfj. in thickness and 100/^ in length in Saccharomyces

Various Forms of Yeast-Fuxgi. «. colonies of round cells (Saccharomyces conglomer-
atus?); b. single cells of different forms ixirtly forming daughter-cells; c, cylindrical cells of
the pellicle-fungus (Saccharomyces mycoderma).

albicans (Fliigge). They proliferate in the following manner : at
or near one or both ends a dilatation appears; this immediately
fills with the contents of the cells, gradually grows into a new
cell, and finally separates itself from the old cell by means of a
transverse wall. The old cell is called the mother-, the new
one the daughter-cell. The latter then forms new cells in the
same way. The daughter-cells either separate themselves from
