ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 227 



French Mycology.* — L. Rolland describes Inocybe re-panda, which 

 had been placed in Entoloma by Berkeley on account of the reddish 

 tinge of the spores. Rolland has found that the colour varies between 

 red, green and brown. He discusses several other forms of Inocybe, 

 and notes the change of colour that may be looked for, and also the 

 change in odour at different stages of development. 



N. Patouillard f publishes a note on the genus Paurocotylis Berk., 

 which has been classed among the Gasteromycetes. Careful re-examina- 

 tion shows that the spores of P. pila, the typical species, are arranged 

 as if in asci, and that, with other characters, places it among the Ascomy- 

 cetes, near to Hydnocystis. The other species P.fulva belongs to the 

 genus Endoyone. 



G. Delacroix % has studied a disease affecting the mulberry trees in 

 Madagascar. The under sides of the leaves were covered with a white 

 coating of mycelial filaments. Conidia are produced singly at the apex 

 of the conidiophores. Delacroix considers it to be a new species, 

 Ovulariopsis moricola. With it is associated a species of Phoma, which 

 he considers also belongs to the life cycle of the fungus. 



Delacroix § has also published notes on Stromatinia Linhartiana, of 

 which the conidial form Monilia Linhartiana grows on the leaves and 

 twigs of Primus Padus, and which he finds to be identical with Ovularia 

 necans. The Peziza form grows on the mummified fruits in the 

 spring of the year, and is intermediate between Sclerotinia Padi and 

 S. Aucuparw. A fungus |j that grows on the bark, leaves and fruit of 

 the pear, apricot, etc., has been described in America as Sphccropsis 

 malorum. Delacroix finds that it is identical with Diplodia pseudo- 

 Diplodia. Macrophoma malorum he considers is another stage of the 

 life-cycle of the fungus. Dothichiza IT populea has been described as a 

 saprophyte on dead poplar branches. The w r riter has proved it to be 

 a wound parasite which kills the tree or branch when it has completely 

 circled it. He also discusses* the rottenness of potatoes caused by 

 Phytophthora infestans. He contrasts the mycelium and especially the 

 haustoria with those found in the fruits of a tomato attacked by the 

 same disease. He describes the effect produced by other diseases, such 

 as scab and gangrene caused by Bacillus caidivorus. Fusarium Solani 

 he considers to be a saprophyte, attacking tubers already invaded 

 by the mycelium of Phytophthora. Finally, he examines the cases of 

 immunity from disease and the influence of the soil on the growth of the 

 potato-disease. 



New British Fungi.f — The mycological members of the Yorkshire 

 Naturalist Union have been successful in adding no less than seventeen 

 species of fungi to the British Flora, and of these nine are new to 

 science. Diagnoses and notes of all the species have been published, 

 and a special account given of an interesting form, Symphosira parasitica 

 Mass. and Crossl. It somewhat resembles a very large species of Stilbum,
