case of a chestnut colour, on whicli the perithecia are 

 now individually visible to the naked eye as yellow 

 granules. The ripe spores have the form of bi-

 which puts out the germinating filament, swells up 

 violently and splits the exospore into two halves. 

 The mycelium which proceeds from the Ascospores 

 produces, like that which arises from the conidia, at 

 first Conidiophores, and afterwards Perithecia.
