media the fungi could hardly be distinguished one from the 
other. The growth was abundant in ail, of a white, creamy 
colour. The fungi grew under Uvo forms : a globular form, 
morphologically similar to a typical yeasl; and a filamentous 
form, sliowing mycelial threads simple or ramified; asci and 
internai spores vvere always absent. 
Comparison with the thrush fungi foimd in the Tropics. — 
Anyone interested in the subject may compare the thrush 
fungi found in London with the moniiia foimd in the tropics , 
by oomparing Table l with Table IL It should be noted lhat 
several of the tropical monilias mentioned in Table II did not 
dérivé from cases of thrush, but from cases of bronchomycosis, 
blastomycosis, «. tea-faciory cough » etc. 
Conclusions. 
1. The term Thrush-Fungus ( moniiia , saccharomyces, 
oidium , albicans ) does not indicate a single species of hypho- 
mycete, but both in temporate and tropical zones lias been 
used to cover a large number of ditferent species. 
2. The fungi found in 11 cases of thrush-stomalitis investi- 
gated by me in London, belonged to seven ditferent species of 
the gémis moniiia Gmelin 1791. For No. 1 species of Table I, 
I propose the term moniiia Metchnikoffi. 
3. The fungi found in the London cases were different 
species from those found in the Ceylon and South Indian cases.
