CASTELLANIA 



Coloniis albidis, humidis, nitidis, pseudomycelio non bene evoluto vel 

 morphologia ignota ; gelatina non liquef acta ; f ermentatio adest. 



The type species is Monilia hronchialis Castellani. 



Colonies white, humid, usually shining, pseudomycelium not well developed, 

 morphology unknown; gelatin not liquefied, sugars fermented. 



After all the species of the imperfect filamentous yeasts have been dis- 

 tributed to existing genera as far as possible, one is confronted with many 

 species which have been described without a sufficient characterization of 

 their morphology. They have mostly been based on a minute description of 

 their reaction with sugars and the coagulation of milk. They constitute the 

 bulk of Monilia as described by Castellani & Chalmers (1913). While it is pos- 

 sible that some species have been included here which will be found to belong 

 elsewhere, it is felt that they make a natural group. They are mostly sapro- 

 phytic or weakly parasitic in lungs, mouth, and intestinal tract. It is with 

 great pleasure that I dedicate this genus to Castellani, who has done so much 

 work on this group. 



There are a few species which differ from the greater portion of the genus 

 in having a thin pellicle on broth. The position of this group of species is 

 uncertain since they have strong resemblance to Pseudomonilia, but it has 

 been thought best to place them here until more is known of their morphology, 

 especially as they differ from Pseudomonilia by their fermentation of sugars.
