season was favourable, and the locality so rich in species, that 612 

 species and twelve varieties were collected in a few days. Three species 

 new to Britain were foxmd—Tricholoma earneolum, Pholiota sororia, and 

 Inocybe commixta. One of the most interesting species met with was 

 Bolbitius Bolton i Fr. A list is added of the fungi collected. 



British Mycolog-y.* — A series of papers are published in the Annual 

 Transact ions of the Mycological Society dealing with various aspects of 

 our fungus flora. An account is given of the annual fungus foray held 

 last autumn at Drumnadrochit in Inverness-shire, and the species ob- 

 served are enumerated. The list is especially rich in micro-fungi 

 collected chiefly by D. A. Boyd. Carleton Rea, the President for the 

 year, gave in his address a resume of Patouillard's scheme of classifica- 

 tion of the Hymenomycetes, with notes on many of the larger fungi 

 from personal observation. Em. Boudier contributes the diagnosis of 

 a new and interesting Discomycete, Pseudo-phacidium Smithianum. It 

 occurs as a parasite on Empetrum nigrum. A. Lorrain Smith supplies a 

 second record in this country of Myxococcus piriformis, the only 

 member of the Myxobacteriaceai that has been detected here. R. H. 

 Biffen records two species of Laboulbeniaceae, Stigmatomgres purpurea* 

 on specimens of Scatella from North Cornwall, and Laboulbenia vulgaris 

 on various hosts, chiefly Bembidium collected at Durnford Fen, Cam- 

 bridge. These are the first record's of the order for Great Britain. 

 M. C. Cooke discusses the identity of Hygrophoris Clarhii : there are 

 three different diagnoses of species, each purporting to be H. Glarhii. 

 Cooke thinks the species had better be ignored, as no one knows which 

 is the true one. C. Crossland publishes a long and useful list of 

 omitted ascus and microscopic measurements of Ascomycetes. A new 

 ( 'lararia is published by W. B. Allen. A. D. Cotton gives notes on marine 

 Pyrenomycetes, new species or new to Britain. An instructive paper, 

 "Recent Work on the Reproduction of Ascomycetes," has been written 

 by H. C. Fraser. It sums up the work done in that branch of* myco- 

 logy, giving succinctly and clearly the new discoveries that have been 

 made by herself and other research workers, and indicating the bearing 

 that these new facts have on the relationships of the different groups. 

 Much work still remains to be done on the subject. T. Petch sends 

 from Ceylon an account of the Bleeding-stem disease of the Cocoanut- 

 tree, caused by a black mould, a species of Thielaviopsis. A series of 

 notes on fungi are contributed by M. C. Cook, and finally the usual 

 lists of new and rare fungi are provided by A. Lorrain Smith and 

 ( arleton Rea. with an additional list by H. C. Hawley. The large 

 number of new species for the year testifies to the good work done by 

 members of the society. 



Gooseberry Mildew.f — J- Eriksson gives an exhaustive paper on 

 this subject. He describes the appearance of the fungus and its occur- 

 rence in America and Europe. In addition to gooseberry bushes 

 it attacks Ribes nigrum, R. rubrum, and R. aureuni. No varieties or
