By Annie Lorrain Smith and Carleton Rea, B.C.L., M.A., &c. 
Chrysophlyctis Schilb. Ber. d. Deut. Bot. Ges. XIV. 1896. 
Sporangia thick-walled, golden brown, without mycelium, spherical, 
containing zoospores, occurring singly or a few together among the 
cells of the host plant. 
C. endobiotica Schilb. 
Occurring on the tubers and lower leaves of the Potato, causing 
gall-like outgrowths, the outer layers of the galls especially crammed 
with sporangia. ‘The sporangia are thick-walled subspherical, vary- 
ing in size, about 60-70 x 50u. I have not succeeded in germinating 
these sporangia, the material I examined was sent in to the Royal 
Agricultural Society in August from N. Wales. 
M. C. Potter describes the same disease sent to him from Cheshire 
in 1900. Journ. Board of Agric. LX. (1902), pp. 320-323, pl. 1. 
There seems to be little doubt that it is the fungus described by 
Schilbersky, though no measurement. or plates accompany his 
description,

Hyphz long, slender, much branched up to Ic.m. in height and 
6°5 to 1°74 in width. Conidia chiefly terminal, spherical, varying 
from about 12 to 28u in diameter, sometimes intercalary and barrel- 
shaped; oogonia terminal from 19°6 to 22°Qu in diameter, antheridia 
usually one to each oogonium, arising from the oogonial stalk, or in 
luxuriant cultures diclinous in origin ; Oospores one in each oogonium 
from 14°7 to 18°34 in diameter, with a smooth, thick, yellowish 
epispore, germinating after a period of rest by one or more germ- 
tubes. Zoospores never developed. 
Saprophytic on vegetable and animal substrata.
