Bicentennary of Linne- — ^In connection with the Linnean celebration at the 



University of Upsala, a series of eight publications has been issued. In general 

 the volumes contain reprints of some of the most interesting minor papers of 

 Linne, which thus become accessible to a far greater number of readers. For 

 example, the '^ Invitation du recteur pour assister aux fetes'' is a paper of 107 

 pages, consisting chiefly of a reprint of Linne's ''Cultur der Pflanzen." The 

 announcements in reference to the conferring of doctor's degrees in philosophy, 

 medicine, law, and theologj' are four volumes of reprints. There is also a special 

 publication, "Linne och Vaxtodlingen," edited by Swederus. The first (pp. 341) 

 of four volumes containing the correspondence of Linne is also included. The 

 most elaborate member of the series is the *'Linneportratt/* prefaced by a colored 

 portrait of Linn^, and containing reproductions of numerous other portraits, 

 busts, medals, etc., as well as a description of the 515 portraits (paintings, medals, 

 etc.) in the collection of the University. The University of Upsala has certainly 

 spared no labor and expense in doing honor to her illustrious professor. — J. M. C 



Genera Siphonogamarum. — The tenth fascicle of Dalla Torre and Harms's"^ 

 list of the genera of seed-plants continues the general alphabetical list of names, 

 the last entry being Macrocarpium. — J. M. C. 



NOTES FOR STUDENTS 



Fungi in termite nests. — Petch gives an account of the fungi found in certam 

 termite nests in Ceylon, which grow from the combs found in the chambers. The 

 fungus flora of the combs in their normal state seems to be limited to few species 

 which occur almost pure. The only form on the normal comb is a hyphomycete 

 which was not determined, but from the descriptions seems to be like Sterigmato- 

 cystis. This fungus seems to be endemic in the nests, according to the author 

 not being found outside them. 



WTien the combs grow old they give rise to two forms of agarics, which, however, 

 the author regards as one species. Both have been described under several 

 names from material sent to Europe, These agarics arise from combs at a con- 

 siderable depth below the surface, so that their roodlke stalks attain an average 

 length of 30^°^. The lower part of the stalk is black, while the upper portion is 

 white. The first form is marked by the absence of an annulus and by the peculiar 

 fact that only a single plant develops from each comb. Although a large number 

 start, only one pushes its way to the surface of the ground. All the other rudiments 

 fail entirely- to develop, so that it is not possible to find specimens which have
