ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 421 



Switzerland. He has embodied the results in a series of tables. He 

 considers that there are a number of different forms or "lines" within 

 the limits of these species. On Cytisus he experimented with Uroinijces 

 Genistse-tinrtorise, and was al)le to detet'mine the ttcidium form on 

 Euphorbia Cyparissins. A. L. S. 



Observations on Puccinia Pruni-spinosse Parasitic on Apple 

 and Uromyces Terebenthi on Pistacia Vera. — Ali Eiza {Bull. Soc. 

 Mi/col. France, 1920, 36, 125-7, 1 fig-.). The author noted the disease 

 of apple-trees at Halkali, and was able to identify the fungus as Pmrinia 

 Frimi-spiiuisse. He also gives anew host for Uroviyces Terebenthi \ he 

 gives a figure of the teleutospore. A. L. S. 



Experimental Study of Puccinia Actaese-Elymi. — Eugene Mayor 

 {Bull. Soc. Mijcol. France, 1920, 36, l-JT-Gl). The author by numerous 

 inoculation experiments has proved that two species, both forming 

 a^cidia on the Helleborus group of Ranunculacea3, are included under 

 the above. The second he designates as F. ActaesR-Argopyri .

Uromyces Airae-fiexuosae. — C. Ferdinandsen and 0. Winge {Bull. 

 Soc. Mycol France, 192 0, 36, 162-4, 2 figs.). The writers have iden- 

 tified the form-rust Uredo Airse-fiexnosse aH a stage of Uromyces Airae- 

 pexuosse sp. n. The latter was found in autumn at Copenhagen 

 growing along with the uredo. A. L. S. 



New Lepiota from Brazil. — X. Patouillard {JjuU. Soc. Mycol. 

 France, 1921, 37, 81-::i). The new species Lepiota Fntteman&ii is dis- 

 tinguished from allied forms by the large size of the pileus (15 cm.), 

 and by the brown-black colour. A. L. S. 



French Hymenomycetes (VII. Stereum). — H. Bourdot and A. 

 CrALZiN {Bull. Soc. Mycol. France, 1921, 37, 103-12). The authors 

 give a synoptic key of Stereum species based on macroscopic characters. 

 They publish a first instalment of descriptions of the species. A. L. S. 



New Species of Polyporacese and some Polypores New to 

 Bengal.— 8. R. Bose {Ann. Mycol., 1921, 37, 129-81, 3 pis.). The 

 new species Fames rufolaccatus was collected in the Simla Hills, India. 

 It is closely related to Fomes pinicola, but differs in the large elongated 

 pores and the soft tissue of the pileus. A. L. S. 



Two New Basidiomycetes. — H. Bourdot {Trans. Brit. Mycol. Soc, 

 1921, 7, 50—1, 2 figs.). The fungi were collected by A. A. Pearson at 

 Weybridge, and submitted to the author for determination. The paper 

 opens with valuable notes on the early forms of resupinales, so 

 different in appearance from the mature stages. Gorticium Fearsonii 

 occurs as a ceraceous-pruinose efflorescence on a pine log. The second 

 species is also a delicate plant like a loose thin crystalline film of ice. 

 Bourdot places it in a new sub-genus of Heterochsete as Heterochsetella 

 rrystallina ; it also grows on pine wood, always in an advanced stage of 

 decay. The distinctive characters of these fungi are described and 

 figured. A. L. S.
