trama a very unusual appearance; these oells probably represent internal oystidia. In T - 

 aria the surf ace of the pileus is never clearh defined; the marginal veil, made up of two 1 

 ers, is bo delicate that it soon disappears. The cells of 1 1 * « - young PluU ■ basidiocarpe ■■ire 

 constantly binucleate. — //• C. Cowles. 



lis?. \\ i; \ n i;k, John .1., and I, in I. I ; i PTOBB. A systematic study of the Proteus group 

 of bacteria, .lour. Bact. 4:331 353. L919, In this study eighty-four "f the Prc4 



groui> were obtained. Various morphological ami cultural tesl a were made upon the different 

 strains and the following conclusions reached: The group may in- divided into i wo genera, 



Proteus and Zopfiu8, the latter a new genUS. Two species are included in the firsl . /'. I "I'jriTin 

 and P. mirahilis, and one in the second, no name being suggested for this species. — '

 1919. — Polyporus tsugae (Murr.) Overholts is found to be a rot producer of dead hemlock tim- 

 ber. It attacks the sap and heart-wood destroying both cellulose and lignin. The fungus, 

 which is fully described, is shown to be different from P. lucidus and P. curlixii. — //. B. Rosen.

 sand-dunes. Trans. British Mycol. Soc. 6: 143-148. 1919. — A considerable number of spe- 

 cies of hymenomycetes, gastromycetes, and discomycetes are listed. The opinion is expressed 

 that the roots and other buried remains of Agropyron and Ammophila provide the means of 

 sustenance. — H. M. Fitzpalrick.

 In this journal, in 1915, an account was given of the occurrence of several alpine species of 

 Uredineae. The present paper supplies additional information on some of these, and records 

 the occurrence of several others. The uredo- and teleutospore stages of Melampsora alpina 

 Juel occur on Salix herbacea, and the aecidial stage of Saxfraga opposilifolia. This stage 

 has been known as Coeorna Saxifragae Went. A long description of this species V3 given. The 

 discovery of the aecidial stage clears up any doubt at to the distinctness of this fungus from 

 Melampsora arctica Rost. The aecidial stage of Puccinia borealis was discovered by Greville on 

 Ben Voirlich in 1821, and has been the only recorded British station. It is now recorded from 

 Ben Lui on Thalictium alpinum. Juel showed that the uredospore and teleutospore stages 

 occur on Argostis borealis. Authoxanthum orodatum may be another host. Infection experi- 

 ments are to be carried out to determine whether this species of grass is indeed another host. 

 Puccinia Polygoni-vivipari Karst. was found on Polygonium viviparum in Perthshire in 1915. 

 The uredo- and teleutospore stages of P. scptentrionalis are also found on Polygonium vivi- 

 parum, but at higher altitudes. The distinguishing marks of the two species are given. P. 

 Polygoni-vivipari appears to be autoecious. Uromyces Onobr ychidis Lev. was found in Kent 

 in cultivated sanfroin. It has not previously been reported from Great Britain. The char- 

 acters are given. Teleutospores had not been found in British specimens of Puccinia Hypo- 

 chaeridis Oud. up to the present time. They were discovered, along with uredospores, on //. 

 radicata at Epsom in 1916. Puccinia Crepidis Schrot. was found on Crepis virens in Perth- 

 shire in 1915. The aecidial stage of P. uliginosa Juel occurred on Pamassia palustris in Ar- 

 gyllshire in 1915. P. major Dietel was found on Ben Voirlich in 1915 in aecidial condition 

 where it occurred on Crepis paludosis. A correction is made of spore measurements of P. 

 Prostii given in Jour. Bot. 53: 44. 1915. — K. M. Wiegand.
