various food-stuffs. He finds that the occurrence of moulds varies 

 according to the quantity of the moisture present. Eurotium repens 

 appears first, then Eurotium rubrum n.sp. With a higher degree of 

 humidity Oidium forms appear, and with a still higher Penirillium 

 glaucum. The author notes the chemical reactions that take place, due 

 to the growth of moulds and bacteria. 



Fungus-Flora of Piedmont.* — Teodoro Ferraris publishes a first list 

 of the fungi from this district, in all 1(>2 species, many of them new to 

 the Italian Flora, and 19 species new to science. These latter are all 

 microscopic fungi, Pyrenomycetes or Deuteromycetes. 



Kryptogamen-Flora.j — A. Allescher continues and concludes the 

 addenda to the group of Fungi imperfecti that he has been issuing. 

 The last two parts issued deal with the remaining species recently dis- 

 covered and described, belonging to the different groups Sphseropsidese, 

 Nectrioideao, Leptostromacege, Excipulacea;, and Melanconieaa. The 

 number of species recorded reaches the total of 5387. 



Fungi Polonici.| — J. Bresadola publishes a list of the fungi collected 

 by B. Eichler. This first contribution includes the hymenomycetes, 

 beginning with the Agaricacerc, down to Corticium. Several new species 

 are included in the list. 



Fungi from New Caledonia. § — P. Hariot and 1ST. Patouillard pub- 

 lish a list of fungi chiefly from the neighbourhood of Noumea and the 

 Island of Pines. They have determined 84 species all belonging to 

 the Basidiomycetes and Ascomycetes. Among the former I they have 

 determined eight species new to science, in the latter group five species 

 are new. The authore give the habitat and locality of each plant. 



Micromycetes rariores selecti.|| — Tycho Vestergren publishes a 

 catalogue with diagnoses and critical remarks on 165 species included 

 in fasc. 11-17 of his Exsiccati. He describes a number of new species 

 belonging to the Hyphomycetes, Splueropsidea}, and Uredinetc, from 

 Eussia, Sweden, Germany, and Austria. 



Rare Sicilian Fungi.^T — F. Cavara describes two 'new fungi, one of 

 which he found on Etna last August. Riccoa sEtnen.sis gen. et sp. nov.** 

 formed a stalked capitate stroma, the disc bearing minute simple sporo- 

 phores with elliptical, hyaline, one-celled spores. He thinks that it 

 may be the type of a new family intermediate between the Stilbaceas 

 and the Hymenomycetes. The other new species, Cerionv/ces siculus, 

 he collected in the botanical garden at Catania. It was characterised 

 by a zonate disposition of the sporogenous layer, and he is inclined on 

 that account to place the fungus rather among the Tuberculariacese 

 than to consider it a form of Polyporus, the place usually assigned to 

 other species of Ceriomyces. The writer also describes a variety of
