ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 325 



Notes on Agaricacese.* — P. Dumee has become convinced of 

 the probable identity of Trklioloma melalencum, T. grammopodium, 

 T. arcuatum, T. hrevipes and T. humile. He describes the points on 

 which these five forms agree, not only the field characters but the 

 microscopic details, such as basidia, cystidia and spores. The cystidia 

 are peculiar in having a cap-like ornamentation at their tips. The 

 oldest name is T. arcuatum, but the author would prefer T. melaleucum 

 as best representing the fungus. 



P. Dumee t has received confirmation of his view that Volvaria 

 speciosa and V. gloiocephala are the same species. A correspondent in 

 Italy watched the development of the former species, and its characters 

 changed during growth to those associated with V. gloiocephala. 



Genus Polyporus.| — 0. G. Lloyd has recently issued a synopsis 

 of the section Apus of the genus Polyporus. The genus as understood 

 by Lloyd consists of soft fleshy species, annuals except in the tropics. 

 Some of them are stalked, more of them are sessile, and it is these that 

 are now described. They are divided and arranged according to the 

 colour of the tissue and of the spores. There are a very large number 

 of species, each of which is carefully described and in most cases figured. 



Fungi from New Caledonia. § — N. Patouillard describes a number of 

 new fungi from the above country. CypheUa crateriformis on decaying 

 branches has an unusually long stalk and a gelatinous consistency. It is 

 a pure white species. A new genus, Catilla Pandani, first placed in 

 the genus CypheUa, is also described ; it is a gelatinous form, and the 

 base of the "cup" is occupied by basidia and by cystidia. The re- 

 maining new species belong to PJeurotus, Hysterangium, Sarcosoma, and 

 NummnJaria. 



Insect Fungi. — G. Arnaud || describes a very large form of Isaria 

 from Madagascar, measuring with the insect a height of 13 c.cm. He 

 identified it as nearly related to Isaria arbuscula. The author takes 

 occasion to review and compare the allied species of Isaria, Mycomalus, 

 and Beauveria with their conidiophores and conidia. 



P. Vincenslf describes a new species of VerticHlium, ^\ Barhozae, a 

 form of Isaria which was found on the chrysalis of a butterfly. It bore 

 a certain resemblance to the fructification of Isaria arbuscida. Another 

 species, Fusarium acremoniopsis sp. n., was taken from a caterpillar which 

 it affected injuriously. Vincens describes the condition of the host and 

 the fungus. 



Comparative Value of Fungicides.** — J. Vargas Eyre and E. S. 

 Salmon have carried out experiments on spraying fungus pests, more 

 especially American gooseberry-mildew. They found that liver-of-sulphur 

 even in weak solutions injured the young shoots. They recommend a
