Revissione delle forme del genere Steganosporium 
Corda by Dr. Alberto Noelli, published in Malpighia, An. XVII, 
Fasc. IX, pp. 412-418, contains descriptions of Steg. piriforme 
Corda, piriforme var. major Ell. & Ev., sesculi Sacc., compactum 
Sacc., muricatum Bon., cenangioides Ell. & Roth., and betulae 
Noelli n. sp. (nei rami di Betula alba). Synonyms and text fig¬ 
ures of the spores are given. 
Infection-powers of Ascospores in Erysipitace^e, by 
Ernest S. Salmon, Journal of Botany, May and June 1903 
(41 :159-165, 204-12) details a series of infection experiments 
with the ascospores of Erysiphe graminis DC. on Hordeum vul- 
gare. Heretofore experiments carried on by several persons have 
proved the existence of “biologic forms” of several species, in the 
conidial stage, of the Erysiphacese. The experiments referred to 
in this paper seem to show conclusively that the infection-powers 
of the ascospores, of which nothing has hitherto been known, are 
restricted in a definite manner. The results of the experiments 
will appear in the Beihefte of the Botanisches Centralblatt. 
A very Comprehensive Treatise on the Fungous Dis¬ 
eases of Grasses is that by L. H. Pammel and J. B. Weems in 
the Iowa Geological Survey, Bulletin 1 (pp. 185-292, 1901). 
Historical and descriptive notes are given of all the common fungi 
occurring on the native and cultivated grasses. Very many text 
figures and plates add much to the value of the article, which will 
prove very useful to beginners and amateurs, and even to pro¬ 
fessional botanists. The date in the preface shows that it was 
completed in 1899, but evidently there was considerable delay in 
publication. Consequently the nomenclature is not always such 
as the American mycologists use to-day. 
Dott. C. Massalonga in Note Micologiche published in 
Malpighia, An. XVII, Fasc. IX, pp. 419-423, discusses the follow¬ 
ing : (1) Sulla causa di un precoce disseccamento delle foglie di 
Quercus pubescens Willd. (with description of Gloeosporium 
nervicolum C. Massal. in litt.) ; (2) Sull antracnosi delle foglie 
di Populus tremula L.; (3) Di un ifomicete che vive parassita 
sul tallo di Candelaria vulgaris A. Massal. (with description of 
Fusarium lechenicolum C. Massal. in litt.) 
A New Species of Geaster is described and figured in the 
Botanical Gazette, 36:303-6, Oct. 1903, by George F. Atkinson; 
it is called Geaster leptospermus Atks. & Coker. It is remarkable 
in its (1) habitat (on bark of living trees among moss) ; (2) be¬ 
longs to the fornicate section of the genus (in which but few
