the spores in quantity under “pure-culture” conditions. It is con¬ 
fidently expected that investigations in the course of another year 
will put it within the reach of any practical and experienced 
grower to develop spawn from spores of selected Mushrooms. 
By such methods one could select the particular Mushrooms from 
which spores are to be taken, and therefore constant selection and 
improvement will become possible. Success has also attended the 
effort to grow “spawn” from bits of tissue of selected Mushrooms 
in test tubes filled with sterilized stable manure or compost. 
The Relationship of Sexual Organs in Plants by Brad¬ 
ley Moore Davis (Botanical Gazette, 38:241-264, 1904), though 
not primarily taxonomic and mycological, is an article that every 
mcyologist will desire to consult. The morphologist chiefly will 
be interested in the new terms used: Sporocyst, Gametocyst, Sper- 
matocyst, Oocyst, Gametangia, Spermatangia (antheridia), Oan- 
gia (archegonia), Coenogametes. 
Oogenesis and Fertilization in Albugo ipomoeae-pan- 
duratae, studies by F. L. Stevens, is published in the October 
No. (1904) of the Botanical Gazette. It is a brief account, illus¬ 
trated with two text-figures, touching only the salient features 
and those which present devergence from the usual types. The 
sexual organs and sexual spores are found in the hypertrophied 
parts of the host in such abundance as to render this species tbe 
most favorable of all of the genus for the study of Oogenesis and 
fertilization. 
A Previsional List of the Fungi of Nova Scotia is pub¬ 
lished by A. H. MacKay, in the proceedings and Transactions of 
the Nova Scotian Institute of Science, Vol. XI, part I, pp. 122- 
143, 1904. Most of the species are the higher fungi; one is doubt¬ 
fully proposed as new, namely, Boletus dartmouthi. 
The growth of Ramularia reticulata is recorded by 
Albert C. Herre in the Botanical Gazette for September, 1904. 
He finds that near the Stanford University, California, various 
measurements showa growth of 17 to 91 per cent, in length from 
September to the following May. A single measurement showed 
that Parmelia caperata, growing on the trunk of Aesculus cali- 
fornicus, in the same time increased 1.5 cm. in longitudinal diam¬ 
eter, and 1.0 cm. in transverse diameter. 
A note in Science, June 3, 1904, by Albert Francis Blakes- 
lee, pertains to a somewhat extended investigation on the method 
of reproduction in one group of the common Moulds. Some of 
the facts are stated as at variance with the conclusions of other 
investigators. Zygospore production (the author states) in the 
Mocurineae is conditioned by the inherent nature of the individual 
species and only secondarily or not at all by external factors. He
