Nomenclature.— A few words are necessary with regard to the 

 nomenclature and the synonjnns, as the greatest confusion has 

 existed with regard to this genus. The first description of the genus 

 Monilia, as we understand it, was given by Persoon as ' Stipitafa, aut 

 effusa byssoidea, Fila moniliformias articulata,' and the first date 

 given by Saccardo 1797, though the earliest we have found is in his 

 book of 1801. The name is derived from monile, a necklace. 

 Link's description in Gmelin's thirteenth edition (really the four- 

 teenth edition) of Linnaeus's ' Systema Natura,' 1791, refers, it is 

 true, to Monilia aurea (Link, 1791), but it was described as Oidium 

 aureum Link, 1791. The other synonjnns do not require explana- 

 tion. 



We have not included the genus Zymonema de Beurmann and 

 Gougerot, 1909, in the synonyms because Z. gilchristi, the cause of 

 American blastomycosis, more usually called Cryptococcus gilchristi,
