capillitium none. The second number is devoted to a consideration of 

 the genus Bovistella, with diagnoses and notes on the species. There 

 are also remarks on some rare Australian fungi, and an account of 

 botanical work at Geneva. 



Tylostomese.* — C. G. Lloyd continues his study of G aster omycetes, 

 and has recently published an account of the Tylostomese. This family 

 includes the genera Queletia, Birtyocephalos, Schizo stoma, Battarrea, 

 Battarreopsis, ChJamydopus, and Tylostoma. The last mentioned is bj 

 far the largest genus, though only one British species is included in it. 

 The plants of this family are, with a few exceptions, of very rare occur- 

 rence. Some of the genera are founded on a species that has been 

 collected only once. Lloyd writes descriptions and notes on each of 

 the species, and they are all illustrated by photographic reproductions. 



Mycorhiza-producing Fungus.f— The fungus in question — Gortin- 

 arius rubipes sp. n. — has been described by C. H. Kauffman. It is 

 distinguished by its brick-red mycelial strands and stem. The colour 

 of the mycelium made it possible to trace its course in the soil, and it 

 was found that it was attached as an ectotrophic mycorhiza to red oaks, 

 a sugar-maple, and to Celastrus scandens which wound round one of 

 the oaks. The fungus was curiously selective ; in the case of Celastrus, 

 it neglected the oaks to attach itself to that plant. Some other trees 

 in the vicinity were also ignored. The writer presumes that "it is 

 ■dependent for its initial attachment on certain environmental factors." 



Notes on various Fungi.J — G. Bainier records work done recently 

 at the School of Pharmacy. Several species of Penicillium, P. Costantini, 

 P. rufescms, and P. patulum, are described and compared. He cultivated 

 the mould, Helicostylum elegans, and found that so many differences 

 were present that it was necessary to remove the plant to another genus, 

 Clmtostylum. Notes and observations are also published on Bispira 

 ■cornuta, the genus Ocemansia, and a new species of Hyphomycete, 

 Acrostalagmus nigripes, so named from the black colour of the stalk, the 

 verticils and conidia being colourless. 



Economic Use of Fungi. § — B. Beissinger calls attention to the use 

 made of the green-coloured wood which is permeated by the fungus 

 Peziza aeruginosa. He proposes to increase the quantity by growing the 

 fungus on beech wood. 



New Fungus Stain. || — F. Gueguen recommends Sudan iii. dis- 

 solved in lactic acid as a coloration of the oily substances in fungi. 

 He gives careful descriptions as to the preparation and employment of 

 that and other stains for fungi. Sudan iii. is useful also in the 

 examination of Lichens, and even in the histological study of the higher 

 plants.
