“Soris minutissimis, punctiformibus, 50—60 y in diameter metien- 
tibus, vix convexis, numerosis, gregariis, subepidermide (macula sub- 
nulla) nidulantibus, griseo brunneis vel melleis ; sporis subglobosis vel 
irregulariter angulatis, 9—11 n in diameter, episporio levi, dilute brun- 
neo donatis; tegumento communi parum distincto.” 
Habitat in foliis Butomi umbellati , pr. Brunn Moravian (Niessl) et 
Breslau Silesiae (Schrceter). 
I have thought necessary and convenient to change the name of this 
Doassansia , dedicating it to Mr. Niessl, the first one who illustrated it, 
because the late Dr. Winter, previous to the reduction of Protomyces 
punctiformis , Xiessl, to Doassansia punctiformis , Schroet . gave the latter 
specilic name to a different Doassansia living on Lythrum hyssopifolium.
