immersed in water. The final conditions are small clavate bodies 
of the order Spheriacei, belonging to the genus Claviceps. The 
Sclerotium of the Elcocharis has been found in this country, but 
we are not aware that the Olaviceps developed from it has been 
met with or induced by cultivation. One method recommended 
for this sort of experiment is to fill a garden-pot half full of 
crocks, over which to place sphagnum broken up until the pot is 
nearly full, on this to place the Sclerotia, and cover with silver 
sand; if the pot is kept standing in a pan of water in a warm 
room, it is stated that production will ensue. Ergot of the 
grasses will not always develop under these conditions, but 
perseverance may ultimately ensure success. 
A species of Sclerotium on the gills of dead Agarics originates 
Agaricus tuberosus, another Agaricus cirrhatus,* but this should 
be kept zn sitw when cultivated artificially, and induced to 
develop whilst still attached to the rotten Agarics. Peziza tube- 
rosa, in like manuer, is developed from Sclerotia, usually found 
buried in the ground in company with the roots of Anemone 
nemorosa. At one time it was supposed that some relationship 
existed between the roots of the anemone and the Selerotia. 
From another Sclerotium, found in the stems of bulrushes, Mr. 
Currey has developed a species of Peziza, which has been named 
BP. Curreyana.t This Peziza has been found growing naturally 
from the Sclerotia imbedded in the tissue of common rushes. 
De Bary has recorded the development of Peziza Fuckeliana 
from a Sclerotium of which the conidia take the form of a species 
of Polyactis. Pezizt ciborioides is developed from a Sclerotium 
found amongst dead leaves; and recently we have received from 
the United States an allied Peziza which originated from the 
Sclerotia found on the petals of Magnolia, and which has been 
named Peziza gracilipes, Couke, from its very slender, thread- 
like stem. Other species of Peziza are also known to be 
developed from similar bases, and these Fuckel has associated 
* Dr. Bull has been very successful in developing the Sclerotium of Agaricus 
cirrhatus.
