ing from one side of the apex. The spores are mostly a little narrower 
below and more aeute. 
Pestalozzia aquatica, n. s. On living leaves of Peltandra Virgin - 
tea, Newfiehl, X. J., August, 1889. Spots amphigenous,chestnut brown 
£ to 1 centimeter in diameter, concentrically wrinkled, border narrow, 
darker, acervuli epiphyllous, erumpent, J to £ millimeter in diameter, 
black, convex, then concave. Spores obovate, 18-20 by 0-7/*, 4-sep- 
tate, end cells hyaline, next to the lower cell subhyaline, two next above 
dark. Crest of three stout (15-20 by 1 /*) hyaline spreading bristles. 
What appears to be the same is found also on leaves of Sarracenia pur¬ 
purea. 
Pestalozzia nervalis, n. s. On veinlets of living white-oak leaf 
from which the parenchyma had been eaten away by some larva, Pa- 
cine, Wis., September, 1888. Dr. J. J. Davis, 3. Acervuli subhys- 
teriiform. Conidia narrow, elliptical or broad, oblong-fusoid, 4-sep- 
tate, terminal cells hyaline, colored part (3 inner cells) about 14 by 6/q 
lower hyaline cell 8-9/*, long, oblique bristle at the apex 8-9/* long. 
Pestalozzia maura, E. & E. J. M. IV, p. 123. Mr. Langlois finds 
this at St. Martinsville, La., on dead leaves of Persea Garolinensis and 
on leaves of QUercus virens and Q. palustris , differing from the Florida 
specimens only in the absence of any spots, the innate erumpent acer¬ 
vuli being scattered irregularly over the leaf and mostly erumpent be¬ 
low. This species is well characterized by its obconic conidia, having 
the two cells next below the upper hyaline cell almost black. 
BLACK SPOT OF ASPARAGUS BERRIES. 
By Charles E. Fairman. 
These berries are of some slight agricultural importance. Thus we 
read in the report of the U. S. Agricultural Department for 1885, p. G13, 
“To save seed the stalks should be cut when the former are scarlet and 
ripe, to be stripped by hand or thrashed off on a cloth or floor, then 
pounded in a wooden mortar with a wooden pestle to break tue outer 
shells. The seeds are then frequently washed to float away the chaff, 
dried in the sun and air and stored.” 
Asparagus berries are liable to a disease which may, for brevity’s 
sake, be called black spot. 
This is due (a) to the growth of fungi in the interior of the berry, 
( b) to growth of fungi on the exterior of the berry.
