ON FRESH WATER ALG.E. 



a shallow cell be necessary, the first ring of cement may be dispensed 

 with, and the whole mounting of the specimen be done in a few 

 minutes. Even with this cement, and the utmost care in mounting, 

 the cabinet should be occasionally inspected, for there will always 

 be some slides into which air will penetrate. When such are found 

 efforts may be made to stop the leak by new rings of cement over- 

 laid upon the old ; but very often entire remounting of the speci- 

 men is the only satisfactory cure. 



Viennese Fungi. — The only fungi that I have seen exposed 

 for sale in Vienna are Truffles from France. Dried slices and 

 fragments of Boletus edulis — common in every shop at which dry 

 food substances are sold — and in the markets Agaricus melleus. I 

 find that Agaricus campestris and Ag. arvensis are well known and 

 eaten, but I have not seen them during my peregrinations. 

 Bushels of Agaricus melleus have been exposed for sale during the 

 past month. — [Ed. Grevillea.] 



Fungus Foray op the Woolhope Club. — During the third 

 week in October some very pleasant excursions were made in the 

 neighbourhood of Hereford, by the members of this Field Club, 

 and their friends. The meeting being held this year at a more ad- 

 vanced period of the autumn than heretofore, a different class of 

 fungi was consequently met with. On the 23rd the Rev. M. J. 

 Berkeley accompanied the members on an excursion to Holm 

 Lacy, where a profusion of Geoglossum olivaceum, P., was found, 

 or rather an interesting variety of this species, in which the stem, 

 although perfectly smooth, was of a bright green colour. It grew 

 gregariously amongst short grass, on a mossy lawn, and will be re- 

 presented in the forthcoming fasciculus of Fungi Britannici 

 Exsiccati. Upon the same occasion were found Agaricus icterinus, 

 Fr., Hygrophorus fornicatus, Fr., and Clavaria curta, Fr., all pre- 

 viously unrecorded as British species. Upon the tables were 

 specimens of the following less common species : — A. gloiocephalus, 

 Fr., Cantharellus umbonatus, P., Hygrophorus Haughtonii, B. & 

 Br., Lactarius uvidus, Fr., Polyporus Schweinitzii, Fr., The- 

 lephor a multizonata, B. & Br., Hyphomyces torminosus, Tul., 

 Marasmius Hudso?ii, Fr., and many others. On the following 

 day an excursion was made to Moccas Court, where specimens 

 of Clavaria purpurea, Mull, CI. umbrina, B., Hygrophorus russo- 

 coriaceus, B. & M., and numerous other highly interesting species 

 were found. During the meeting the following papers were 

 read : — Mr. C. E. Broome on " New Genera of Fungi ;" Mr. 

 James Benny on " Saprolegniei ;" Mr. Wm. Phillips on " The 

 Fungi of Charcoal Beds;" and on "The Fungi of Gerarde's 

 Herbal," by the undersigned 



King's Lynn. Charles B. Plowright.
