42 SetchelL — An Examination of the Species 
part of August and show many sori already long past 
maturity. 
Distribution. Known only from the original locality at 
Green Pond, Morris Co., New Jersey! 
Literature. 
Doassansia decipiens , Winter, Journ. Myc., Vol. I, p. 102. Aug. 1885.

The three species just described are not readily distinguished 
from one another by the characters of the sori, and need to 
be carefully studied from living material. They certainly 
form a group distinct from that which clusters about D. 
alismatis as a type. They all have the spores compacted 
into sori, and readily separating at maturity. They have, how- 
ever, no cortex of sterile parenchymatous cells, as the species 
of Doassansia should have. On the other hand, they are 
to be distinguished from the species of Entyloma as described 
by De Bary (Bot. Zeit. Bd. 32, p. 107, 1874), and as found 
also in E. compositarum , E. lobeliae , E. menispermi, and E. 
physalidis , by the possession of distinct sori. But there are 
species still included under Entyloma , such as E. crastophilum , 
which approach them in this respect. Where this group of 
species is to be referred ultimately can only be settled by a 
careful study of the greater part or all of the species of 
Entyloma . They do not belong to the genus Doassansia , 
Cornu, but are to be included for the present at least under 
Entyloma.
