phore terminates in a flaring cup and the spores are formed by a 

 budding process in the bottom of the cup. As spores are successively 

 formed in this manner they are held together in a spherical mass by

some adhesive substance so that a ball of spores is often observed 

 at the mouth of the conidiophore. The depth of the cup in an old 

 conidiophore makes this a semi-endogenous type of sporulation. This 

 is the typical manner of sporulation in P. verrucosa, but careful ex- 

 amination of some strains has shown that rarely a few conidiophores 

 bear conidia terminally and laterally in a manner similar to that 

 seen in P. Pedrosoi.
