This is tlu^ more advanced state of Phi/llot^NcIa Taraxaci, the 

 si)ores of which were found in some pycnidia in largi' numbers mixed 

 with the more mature septate sjiores. and some ]n'cnldia had only the 

 simple spores, diifering from lIoUos's description merely in being 

 ])ert'ectly colourless. 



It is ])robable that Sept or i a Taraxaci Hollos {ibid. p. -102; Sacc. 

 ihiil. ]). 1107) is another form of si)ore in the same life-cycle, even if 

 not a further develo])ment of the utncoc/ii//<( as that is of the Plit/llo-
