On dead leaves of Aira caespitosa. 



A true Mollisia ; when young and incurved, brown, when 

 fully expanded entirely white or pallid. Berkeley says: 

 " When old it bears some resemblance to pale forms of P. 

 atrata and P. palustris. The minute speck of down at the 

 base is completely covered when the plant is fully expanded, 

 and cannot be considered as a tapesium or subiculum." 



Type specimen examined.
