infecting generation after generation of Lolium plants without 
spore generation. Professor Freeman also says that the nature 
of the fungus still remains an open question. “I have previously 
enumerated the objections to the assignment of this fungus to 
the ergot-forming parasites and it certainly has little or no 
resemblances to the Uredineae. Nor has it any similarity to 
the Hyphomycetes and Pyrenomycetes of molded grains. The 
Ustilagineae seem to furnish the closest affinities.” 
Terminology of the spore-structures in tpie Uredine- 
ales, J. C. Arthur, Bot. Gaz. 39:219-222, March 1905, contains 
this suggestion relative to proposed designation: “The new terms 
consist of four words, with their derivatives, one for each of the 
four stages of uredineal fungi. For the sorus of the initial 
stage, usually designated by a cipher, and called spermogonium, 
pycnidium, etc., I propose pycnium; derivatives pycnial, pycnio- 
spores, etc. For the sorus of the first spore-stage, usually desig¬ 
nated by the Roman numeral I, and called aecidium, roestelia, 
peridermium, etc., I propose aeciurn; derivatives aecial, aecio- 
spore, etc. For the sorus of the second spore-stage, usually des¬ 
ignated by the Roman numeral II, and called uredosorus, etc., 
I propose uredinium (uredo) ; derivatives uredinicd, uredinio- 
spore or if preferred uredospore, etc. For the sorus of the third 
spore-stage, usually designated by the Roman numeral III, and 
called teleutosorus, I propose telium; derivatives teiial, telio - 
spores, etc.” 
The common Ithphallus impudicus, generally consid¬ 
ered to be a saprophyte only, has been found to be the cause of 
a destructive root rot of the vine in Hungary. According to the 
account given by Istvanffi (Ann. Inst. Cent. Ampelologique Roy. 
Hongrois 3: 1-55, 1904) the subterranean part of the stem is 
entwined by a network of the characteristic cord-like strands 
of mycelium of this fungus. From these, branches are sent into 
the interior of the stem. Small roots are totally destroyed by 
strands which penetrate them lengthwise, destroying all the 
tissues and leaving only the thin decaying cortex. In the older 
roots the cortex and phloem are totally destroyed, leaving only 
a mass of debris. The wood cylinder is last attacked, but this 
also is finally destroyed, leaving only scattered remnants of the 
vessels. [H. Hasselbring in Botanical Gazette.] 
Sexual Reproduction in the Rusts by A. H. Christ¬ 
man, Botanical Gazette, April 1905, can not be sufficiently indi¬ 
cated in a word but possibly the following quotation may show 
the trend of the article: “Maire’s conception that the nuclear 
fusion in the teleutospore is a mixis, was developed on the basis 
of the belief that no real cell fusion occurs in the life cycle of 
the rusts. It is at least a fair presumption that while no nuclear 
fusion occurs in the aecidium, the fusion of gamete cells described
