THE MOULD-FUNGI.

FIG. 22. 



Monilia Candida, after Hansen : A, growth in beer-wort or other saccharine 

 nutritive liquids ; B, cells of a young film-formation ; G (p. 102), growth 

 of mould : forms like a are frequent ; they consist of chains of elongated 

 more or less thread-like cells, rather loosely united ; at each joint there 

 is generally a verticil of oval cells, which readily fall off ; b represents 

 another form, also very frequently occurring, but distinguished from the 

 former by having no verticillate cells ; instead of these there generally 

 issues from every joint a branch of the same form as the mother cell, but 

 shorter ; the links of these chains are not seldom closely united together, 

 the constrictions in many cases disappear, and a very typical mycelium, 

 with distinct transverse septa (c), is produced ; the forms b and c occur in 

 the nutritive medium, a commonly on the surface. Forms like d have 

 much resemblance to Oi'dium lactis. e shows a chain of pear-shaped cells 

 with verticils of yeast-cells resembling Sacch. exiguus ; the chain of 

 lemon -shaped cells represented at /closely resembles Ehrenberg's figures 

 of Oidium fructigenum. Between the principal forms here described 

 there are numerous yeast cells of different forms, and differently arranged 

 in colonies ; as is usually the case, there also appear forms like Sacch. 

 conglomerate Reess.
