BURRILLIA DECIPIENS (Wint.) Clint, n. nom. — Doas- 
sansia decipiens Wint., Journ. Mycol. i :io2. 1885. 
Host: Limnanthemum lacunosum, N. J. (type). 
The spore J balls of this species have no definite cortical layer 
and for this reason it has been placed by the writer under 
Burrillia. 
BURRILLIA ECHINODORI Clint, n. sp. — Doassansia 
alismatis of Hark, in Proc. Calif. Acad. Sci. II, 2:231. 1889. 
Sori in the leaves, forming irregular to sub-circular areas, 
showing spore-balls as closely clustered very minute elevations 
on both surfaces of the leaf; usually a single spore-ball occupying 
entire section of leaf between layers of the epidermis, more or 
less merged sidewise, often irregular but chiefly oblong to sub- 
spherical, without distinct cortex but composed of sterile cells 
and spores intermixed; sterile cells light reddish brown, with 
thinner walls than the spores and more irregular in shape and 
size; spores light-colored, chiefly ovoid to spherical, occasionally 
somewhat flattened, apparently thick-walled, 12-18 n in length. 
Llost: Echinodorus rostratus, Calif., Fla. (type). 
This species was, apparently, first reported from California 
by Plarkness, who called it Doassansia alismatis. Setchell evi¬ 
dently made an examination of this material as he states that it 
is not this species but an Entyloma with a compact sorus. The 
writer’s description is based on a specimen in the herbarium of 
the U. S. Dept. Agr., Div. Veg. Path, and Phvs., collected by 
Simson in Florida in 1892. Sections from this material show 
that the sori have no definite cortex and that the spores are 
larger and thicker walled than either Doassansia alismatis or D. 
sagittariae to which the species has superficial resemblance. 
The sori are also much larger; these larger sori in some cases, 
however, appear to be due to a very complete fusion of smaller 
sori. The peculiarity of the species is that the sori are not com¬ 
posed entirely of spores but of sterile cells and spores intermixed. 
The sterile cells are not strikingly different from the spores but 
have more the appearance of the ordinary cortical cells. Upon 
staining with eosin the spores become more evident through their 
thicker more regular walls.
