Trichias—The banded-spore., Geo. A. Rex. (Journ. Mycol., ii., 
pp. 85-87.) 
Of the three species of the Slime Mould genus 7richia dis- 
tinguished by reticulated or banded spores, only 7: chrysosperma, 
Bull., has heretofore been recorded as American. Dr. Rex now 
finds plants which nearly answer the descriptions of 7. affints, 
De By., and 7. Fackii, Rostfki. A list of specimens from widely 
separated localities is given. 
Vancouveria. Asa Gray. (Botan. Gazette, xi., pp. 182, 183.) 
Dr. Gray dissents from M: Franchet’s views (Bull. Soc. Bot. 
France) that the genus should be merged in Epimedium. 
Variation in Cultivated Plants. W.W. Tracy. (Proc. Sixth 
Meeting Soc. Prom. Agric. Science, pp. 45-48.) 
Vitality of Seeds buried in the Soil. W. J. Beal. (Proc. Sixth 
Meeting Soc. Prom. Agric. Sci., pp. 14, 15.) 
Wellingtonia gigantea. (Gard. Chron., xxvi., p. 18, f. 4.) 
Trees of the giant Seguoza, planted in Lancashire, England, 
in the autumn of 1864, have now reached a height of 40 feet, 
and are 8 feet in circumference just above the base. A repro- 
duction from a photograph illustrates one of the trees. 
Woods and their Destructive Fungi. P. H. Dudley, C. E. (Pop. 
Sci. Month. xxix., pp. 604-617, illustrated.) II. 
The practical side of the subject, detailing the action of fungi 
on telegraph poles, fence posts, ties and timbers, with descrip- 
tions and illustrations of their special enemies, and their mode of 
attack, are here given. The article concludes with a discussion 
of the various methods of preserving wood and an estimate of * 
the annual loss in money to the railroads in this country result- 
ing from the action of fungi. 
Botanical Notes. 
Annuario del R. Instituto Botanico di Roma. Edited by R. 
Pirotta. We have just received the first four fascicles of this 
valuable periodical, illustrated by twenty-eight beautiful litho- 
graphs. Besides several interesting general articles, there are 
enumerated the fungi, lichens, alge, and hepatics from the vicinity 
of Rome. In the last fascicle a new species of Plagiochila is 
described and figured.
