Perithecia scattered, globose, one or more immersed in a mi- 

 nute brown spot arising from the delicate mycelium ; asci cylin-

When young, consisting of little tufts of short tawny threads 

 resembling in structure, though not in colour, those of R. viola- 

 cea; creeping below, erect above and slightly branched, and 

 bearing apparently at their tips subglobose conidia •003-*004 

 inch in diameter. The tips at length acquire a violet tint, which 

 gradually spreads as the tufts become compact and converted 

 into sclerotiiform bodies as large as a grain of mustard-seed, 

 which are connected with each other by a violet web. These 

 bodies are in general quite smooth, but occasionally they retain 

 about them little tawny patches which still show traces of the 

 original threads. There is no papillaeform apex as in R. Cro- 

 corum. 



This appears to be the first time that anything like fruit has
