much research. Eriksson has gone over the whole groand and made 

 many cnltural experiments. He considers that even yet there have been 

 too few experiments with the Uredo stages, and some of his decisions are 

 only provisional. He has delimited three species : — (1) Puccinia caricis, 

 diffusa n. nom., the Uredo-teleuto stage of which is on eight different 

 Carices, the fecidinm stage on Urtica dioica {U. urens), and also on Eibes 

 grossuJaria {R. ruhrum, R. aureum) ; (2) Puccinia caricis-urticee on 

 eighteen species of Car ex, the t\3cidia on Urtica dioica (U. urens) ; 

 (3) Puccinia caricis-ridis, the ascidial form of which grows on species 

 of Eibes. He distinguishes here three sub-species : —Purcinia caricis- 

 ribis-difusa n. nom., and P. caricis-grossidariae n. nom., with a wider 

 range of ajcidial hosts within the genus Ribes ; lastly, P. caricis-ribes- 

 nigri n. nom. on Ribes nigrum, chiefly with three forms, according to 

 the Carex on which the Uredo-teleuto stages are developed. Full details 

 are published of the various cultures. A. L. S. 



Indian Hymenomycetes.— S. R. Bose {Reports Ind. Assoc. Cult. 

 Sci., 1920 (191S), 136-43, 13 pis.). A series of Agarics and Polypores 

 illustrated by photographic slides has been published by Bose. A full 

 description of each species is given, with notes as to habitat and biological 

 data. ■ A. L. S. 



Contribution to the Study of Fructicolous Fung-i in Belgium. — 

 El. and Em. Marchal (Bull Soc. Rog. Bot. Belgiqae, 1921, 54, 109- 

 39, 2 pis.). The investigation was conducted mostly on fleshy fruits. 

 The fungi found on these were isolated by cultivation, and an account 

 of them is given. The species determined belonged to Phycomycetes, 

 Ascomycetes and Fungi Imperfecta In all, sixty-seven different species 

 were identified ; twenty-four of these as species or varieties are new to 

 science, and twenty-one new to Belgium. Those known to be harmful 

 to fruit are indicated. The research is still being prosecuted, and 

 considerations affecting fruit preservation are attended to. A. L. S. 



Schedse ad Mycothecam Boreali-Africanam. — Rene Maire {Bidl. 

 Soc. Hist. Nat. Afrique du Nord, 1917, 8, 242-61, 6 figs. : 1919, 10, 

 130-51, 3 figs., 1 pL). In these two papers the author records the 

 fungi of fascicles 10-12 and of fascicles 13-16. The numbers run from 

 251-400 ; the list consists mostly of records of species already described, 

 but with new localities and with habitats. A number of species, mostly 

 Uredinea, are diagnosed. The plate gives a fine representation of a 

 new Phurotus, P. guccse, which grew on dead or dying trunks of 

 Yucca ehpliantipes Reg., of which it is a wound parasite, killing the 

 tree in one to three years after attack. A. L. S. 



Studies of Basidiomycetes. — A. Sartory and L. Maire {Saint- 

 Xicolas-de-Port, 1918). The authors have issued three pamphlets. The 

 first, " Synopsis du genre CoUgbia " (226 pp.), gives diagnoses, sviionymy 

 and critical notes of the species found in France. Synoptic tables are 

 drawn up and a few figures are used to interpret difficult points. The 

 second, on Tricholoma (158 pp.), follows the same lines. Habitats, and 

 in some instances localities, are included in both monographs. The
