cystocarps, made by Hauptfleisch ; and draws comparisons between bis 

 own results and those of Phillips on other species. 



Algae of Verona.* — Achille Forti gives a short account of the 

 work published by various authors on the algas of Verona and the neigh- 

 bourhood, and this is followed by a list of 173 species of Florideae, 

 Characeae, and Chlorophyceae. The list is to be continued. 



Algae of Jamaica. f — F. S. Collins publishes a list of algae, in- 

 cluding a few fresh- water species, from Jamaica, mainly founded on 

 collections made by Mrs. Pease and Miss Butler, Dr. J. E. Humphrey 

 and Dr. Duerden. The new species here described are : — Scytonema 

 conch opJiilum Humphrey, a shell-boring species, Diplochsete solitaria 

 representing a new genus of Chaetophoraceae, Cladophora intertexta, 

 Dictyerpa jamaicensis, a new genus of the Dictyotaceae, Goniotrichum 

 Humphreyi, Cordylecladia Peasise, and Antilhamnion Butlerise ; the new 

 varieties are : — Oscillatoria princeps forma purpurea, Sargassum vulgar e 

 forma ovata, and Callithamnion byssoideum var. jamaicensis. Tables are 

 given, comparing the marine flora of Jamaica with the floras of New 

 England, Great Britain, the northern coast of Spain, the coast of 

 Morocco, the Canary Islands, and Puerto Eico. A graphic account is 

 given from notes by Mrs. Pease, of the manner of collecting and the 

 appearauce of certain algae when growing. Notes by the same collector 

 are also inserted occasionally under the species names in the list and 

 add to the general interest of this paper. 



Fungi. 



Coprophilous Fungi II. t — G. Massee and E. S. Salmon describe 

 experiments which prove that the various species of Fungi occurring 

 on dung originate from spores swallowed by the animal along with its 

 food. The enumeration of species, which is arranged systematically, 

 includes several that have occurred on the dung of exotic animals, ob- 

 tained from the Zoological Society's Gardens. Two new genera are 

 described: Araclmomyces (Perisporiaceae), with two species; and Gym- 

 nodochium, related to Berkeley's Endodesmia (Tubercularieae). New 

 species have been found in the following genera of Ascomycetes : — Asco- 

 desmis, Arachniotus, Myxotrichum, Chsetomium, and Nectria, and of Hypho- 

 mycetes in Ceplialosporium, Acremonium, Sepedonium, CEdocephalum, 

 Trichothecium, Trichosporium, Chvetostroma, and Graphium. A large 

 number of species new to the British Flora were also recorded. 



Fertilisation of Pythium de Baryanum.§ — This fungus, which 

 causes the damping-off of seedlings, has been investigated by Kiichi 

 Miyake at Cornell University. He gives a historical sketch of previous 

 researches on the fertilisation process in Pythium. The improved 

 methods of the present day have enabled him to arrive at more definite 

 results than was possible to older workers. Nuclear division in the 

 sexual organs he finds is similar to that which takes place in Cystopus 

 .and Peronospora. Of the many nuclei in the oogonium and antheridium,
