INVERTEBRATA, CRYPTOGAMIA, MICROSCOPY, ETC. 673 



first century of wliicli is already issued. Six new species are de- 

 scribed, viz. Cyphella pezizoides, Puccinia Sydoiviana, Sclerotinia 

 Batschiana, CJuctomium botrychodes, Entyloma bicolor, and Thielav'ia 

 hasicola. In addition to a complete enumeration of the myco-flora, 

 the work will contain also a treatise on the classification of fungi. 



Ceriomyces terrestris.* — The fungus previously described under 

 this name by Schulzer of Miiggenburg, and referred by him to Corda's 

 genus Ceriomyces, is stated by the same authority to have been erro- 

 neously so referred, and to belong in reality to the genus Dcedalia. 

 He has now found it in three distinct forms, differing greatly in 

 appearance and habit, but always retaining a uniformity in the size 

 and form of the sjiores, nearly spherical, and from 3 to 7 mm. in 

 diameter. From this peculiarity he proposes for it the amended 

 name Dcedalia lyolymorplia. He considers it to be a transitional form 

 between the Clavariacei and the Pileati. 



Vine-pock.t — Under the name of " Pocken-kraukheit " is known 

 a disease of the vine caused by the parasitic fungus Gloeosporimn 

 ampelophagum, which has appeared since 1876 in Italy and the 

 southern provinces of Austria, and which often destroys a fourth or 

 even a half of the crop. The fungus forms brown spots, with a grey 

 or reddish bloom in the centre, which are at first nearly circular, but 

 subsequently often coalesce. They consist of several layers of pale 

 brown polyhedral cells, which are colourless above, and are there 

 narrowed into short sterigmata or conidiophores. The conidia 

 (spores) are short, elliptical or ovate, colourless, 5-6 mm. long, and 

 2 '5-3 "5 mm. broad. The development and rapid spreading of the 

 fungus depends on the conditions of moisture. It is recommended 

 to remove and burn the infected parts. 



Prehistoric Polyporus.| — Von Thiimen describes a piece of a 

 Polyporua collected, among other prehistoric objects, in the pile- 

 dwelling station in the neighbourhood of Laibach. The state of the 

 jireservation was sufficient for the structure to be made out without 

 difficulty, and for the fungus to be identified with the existing Poly- 

 porus fomentarius. It may have grown on a tree in the station itself, 

 or have been brought in from outside by the inhabitants to be used 

 for the purpose of tinder. 



Relationship of Ozonium to Coprinus.§ — 0. Penzig has care- 

 fully investigated tlie hintory of the structure known as Ozonium Lk. ; 

 and has come to the conclusion that under the name of Ozouiinn 

 auricomnm have been united a lunubor of bodies all of which consist 

 of sterile mycelia of various stages of Coprinus, wliich greatly resemble 

 one another, but which exhibit minuto differences in their size, tlio 

 diameter of the hyphao, tlie transverse septation, &c. From among 

 them ho proposes to establish a new species, Coprinus intermcdius.
