On Conopodium denudatum (Bunium flexuosum). 
BIOLOGY.—The mycelium is perennial. I have cultivated in my 
garden for four years plants of Bunium in a flower-pot, which are 
annually affected with the fungus, but they have never produced the - 
zecidiospores. Although this fungus is very common around King’s 
Lynn, yet I have never found the 4ccdium bunii, which continental 
botanists consider to be connected with it.
