Jan. 1906] Notes from Mycological Literature

September 1904. It is the only species known which occurs para¬ 
sitic on leaves. Looked at from above, the author says in speak¬ 
ing of the leaves, the host appears to be attacked by a leaf- 
parasite and it is quite surprising to find on the lower surface 
the sporophores of one of the Polvporaceae. The pileus is 
5-8 mm. in diameter and 0.2-1 mm, thick. 
Tycho Vestergren, Monographia der auf der Legumi- 
NOSEN-GATTUNG BAUHINIA VORKOMMENDEN UrOMYCES-ArTEN, 
in Arkif foer Botanik, K. Svenska Vetenskaps-akademien I 
Stockholm, Band 4, No. 15, is an important monograph, the sub¬ 
heads being Morphologische Uebersicht, Verwandtschaftsver- 
haeltnisse, Uebersicht der Species and Diagnosen der species. 
The spores of 17 species included in the paper, each fully de¬ 
scribed, are illustrated on two lithographic plates. Eleven of 
the species are new. Most of the species are from South Amer¬ 
ica (one only occurs in Europe) but a few also have been found 
in Mexico and the West Indies. 
A new Genus of Ascomycetous Fungi by Nathaniel Llyon 
Gardner forms vol. 2, No. 6, pp. 169-18, pi. 18, University of 
California publications, Botany, issued July 27, 1905. It is based 
on Sphaeria (Hypocrea) setchellii Hark., a species that was pub¬ 
lished some years ago. The generic name proposed is Nigro- 
sphaeria; its scant mycelium penetrates the subhymenial tissues 
of the host — in the case investigated this being the saprohytic 
Pseudhydnotria Harknessii, which grows in sandy soil. Both 
host and parasite are ascomycetous fungi. 
The Polyporaceae of North America — X. Agaricus, 
Lenzites, Cerrena and Favolus, by William Alphonso Murrill, 
Bulletin of the Torrey Botanical Club, 32: 83-103, February 1905, 
treats of plants with variable daedaleoid or lamelloid hymenium 
and light-colored context and spores. The author says they 
recognize none of the ordinary specific or even generic limita¬ 
tions of the group and that if they are amenable to ordinary 
methods of cultivation, they would surpass Oenothera in supply¬ 
ing most excellent examples of mutation. The treatment of the 
subject is similar to that in previous installments and needs no 
further elucidation. It might be remarked that it is not altogether 
unappalling to some botanists to see the name Agaricus trans- 
' ferred to our common Daedalea quercina — and whether Mr. 
Murrill’s nomenclature and many new genera of the Polypora¬ 
ceae will be accepted by the older workers remains to be seen. 
Organisms on the Surface of Grain with special ref¬ 
erence to Bacillus coli, by Haven Metcalf, Science, N. S., 
22: 439-441, 6 Oct. 1905, is a preliminary note on work done in 
the Piedmont region and the Rice-belt of South Carolina, in 
1903-4. Some of the conclusions are as follows: An immense but
