xlviii PBOCEEDINGS OF THE 



of zygospores in all the species of Mucorini; but they are perhaps 

 justified in transferring Syzygites to Mucor, under the name of 

 Mucor Syzygites. Some useful remarks are appended as to the 

 necessity of a large reduction of the genera of the Mucorini ; and 

 it is suggested that the arrangement of the species must remain in 

 suspense, starting with six well-defined ones, viz. Mucor Syzygites, 

 M. Mucedo, M. Fhyeomyces, M. macrocarptis, and M. fusiger. 



The rest of the paper under consideration relates to a peculiar 

 mode of development of the conidia of Peronospora infestans 

 (the Potato-disease fungus), and to the germination of the oospores 

 of P. ValerianellcB, which have been observed to produce germ 

 filaments similar to the mycelium of the species, and not to 

 yield zoospores. 



To those mycologists who are particularly engaged in the study 

 of the Discomycetes may be recommended a pamphlet published 

 at Genoa in 1864, by M. de Notaris, under the title " Proposte 

 di alcune rettificazioni al profile dei Discomiceti." The author is 

 of opinion that the genera of this large division, defined, as he 

 says, by Pries in the ' Summa Vegetabilium Scandinavise ' con 

 singolare perizia, required to be reconsidered with reference to tlie 

 light thrown upon the group by recent investigations. 



A fourth number of Holfmann's 'Icones Analyticae Pungorum,' 

 a work devoted to the development and minute anatomy of 

 fungi, has just been published. 



The efi'ect of fungi in the production of cutaneous disease is a 

 question upon which recent investigations afibrd very little satis- 

 factory evidence. The hopelessly irreconcileable opinions of 

 the best French and English authorities lead only to the conclu- 

 sion that either one side or the other has a very imperfect notion 

 of the causes of the diseases committed to their care. The fear- 

 ful complaint (not belonging to the cutaneous class) known as 

 the fungus-foot of India, has been the subject of careful investi- 

 gation by Dr. H. J. Carter, Dr. H. V. Carter, and Mr. Berkeley ; 

 and the results of their inquiries will be found condensed in a 

 short but very interesting paper, published in the 8th vol. of the 

 Journal of the Linnean Society. 



The use by the Eussians of the well-known Phallus impudicus 

 in medicine has been the subject of an interesting paper by Dr. 

 Kaleniczenko, in the 25th vol. (p. 529) of the Prench periodical 

 ' rUnion Medicale'*. The fungus is collected both in the young 

 and mature condition. The gelatinous contents of the young
