Oct. 1903] Notes from Mycological Literature

matic aspect it may be said that the name accepted by us (i. e. 
Corda’s name) is rejected by Mons. Maire, his statement being: 
“En resume, a notre avis, les denominations anterieures a la 
decouverte de la tete condifcre, e’est a dire a Costantin, doivent 
etre releguees dans le chaos des anciens noms douteux et inap- 
plicables.” As two species are involved his list is as follows: 
I. Botryosporium pyramidale Cost.; 2. Botryosporium long- 
ibrachiatum (Oud.) Maire, (Botrytis longibrachiata Oud., B. 
[Polyactis] doryphora Pound & Clem., B. pulchellum R. Maire, 
Cephalosporium dendroides Ell. & Kellerm.) 
Bacteria in Modern Economic Agriculture is the title 
of an instructive article by Professor Albert Schneider in the 
August number of the Popular Science Monthly (66:333-343). 
The Rhizobia, or Nodule Bacteria, “assimilate free nitrogen in 
artificial culture media or when not symbiotically associated with 
leguminous plants.” Therefore it would seem probable that 
Rhizobia of leguminous plants might be modified by culture 
so as to induce them to grow on the roots of other plants, say 
corn, wheat, rye, barley, etc. Experimental results are not yet 
conclusive, yet “the indications are that they will finally prove 
successful.” Then there may be other organisms or soil bacteria, 
not found in leguminous root nodules, that can fix free nitrogen, 
and which may be especially adapted to gramineous plants. “It 
would appear that the Bacillus ellenbachiensis of Caron is such 
an organism. ... It would be especially advantageous, be¬ 
cause, in contradistinction to Rhizobia, it forms spores. Spore¬ 
bearing cultures would be desirable because they would keep bet¬ 
ter and longer.” 
The Fifth Installment of the Polyporaceae of North 
America, by William Alphonso Murrill, is published in the Bul¬ 
letin of the Torrey Botanical Club (30:423-434, Aug. 1903). 
The genera Crytoporus, Piptoporus, Scutiger, and Porodiscus 
are included, the species being those found chiefly under the 
genus Polyporus in Sacardo. Those treated formerly (groups 
of the genus Fomes, as this term is generally used) are for the 
most part perennial with large stratified sporophores. The plants 
included in this paper are annual and their fruit-bodies are less 
conspicuous, their mycelium being usually comparatively lim¬ 
ited in extent. They are mostly terrestial, somewhat fleshy and 
allied to the Boletaceae. Full synonomy, notes and distribution 
are given. One new genus is proposed, also three new species; 
ten new names (or new combinations) are given.
