parisons with other Similar Societies, Conclusion. The author 
says the facts show clearly some very evident adaptations in 
Lichen thalli. 
Dr. G. P. Clinton has published an exhaustive mono¬ 
graph on the North American Ustilagineae, Proceedings of 
the Boston Society of Natural History, Vol. 31, No. 9, p. 329-529, 
October, 1904. This is based on his study of this group for sev¬ 
eral years under exceptionable advantages. He gives keys to the 
genera, full synonomy, cities exsiccata, names hosts and indicates 
distribution by States. All descriptions are newly written; there 
are included also a list of host-plants alphabetical under Families, 
Distribution of Species by Continents, Literature (203 items), In¬ 
dex to Synonyms, and Types are cited. Several species are re¬ 
duced to synonyms besides those given in the preliminary paper 
(in Jour. Mycol.) ; a dozen additional species are included besides 
another dozen of New Species. Illustration of all North Ameri¬ 
can species by spore drawings we are told is under consideration.

In Dritter Beitrag zur Pilzflora von Tirol von Fr. Bu- 
bak und J. E. Kabat, published in Oesterreichische Botanische 
Zeitschrift (the last installment in Mai 1904), many new species 
are described, also one new genus, namely, Colletotrichopsis. It 
differs from Colletotrichum durch die Lage der Borsten, die hier 
als eine Pyknidenwand fungieren. 
P. Hennings describes several new species in Hedwigia, 
43:147-9, Mai 1904, under the title Einige neue Pilze aus Cos¬ 
tarica und Paraguay. Of special interest we note his new species 
of a Rust on the potato, no uredineous species being hitherto re¬ 
ported on this host. The parasite in question is given as follows: 
Puccinia Pittieriana P. Henn. n. sp., auf lebenden Blattern von 
Solanum tuberosum L. 
Professor B. M. Duggar publishes as the first report 
on his extended studies of Agaricus campestris, Farmers’ 
Bulletin No. 204 (1904) on the Cultivation of Mushrooms. The 
description of the plant is followed by notes on Spores and Spawn, 
Commercial Mushroom Growing, Mushroom Enemies, etc. He 
points out the necessity of getting so-called virgin spawn which 
has never exhausted itself by the production of Mushrooms. It 
is now possible by means of chemical stimulation to germinate
