80 SUMMARY OF CURRENT RESEARCHES RELATING TO 



New Discinelia.— W. D. Buckley {Trans. Brit. Ilt/col. Soc, 1920, 

 6, pt. 4, 346-7). The new species was found at Slough in May 1920, 

 growing among moss under Uldx. It approaches nearest to D. Menziesi 

 Bond., but is smaller and pearl-grey with a touch of pink, as contrasted 

 with the rose colour of the former. A. L. S. 



Conidia and Paraphyses of Pezicula eucrita Karst. — J. S. Bay- 



Liss Elliott and H. C. Chance ( I'm;? s. Brit. Mycol. Soc, 1920,6, 

 pt. 4, 353-4, 1 fig.). The spores of this fungus may often germinate 

 in the ascus, and conidia can be seen arising on the germ-tube ; they 

 are linear and are produced on any part of the spore or germ-tube in 

 chains, in bunches or singly. The paraphyses are long and slender, and 

 branched or unbranched. The excipulum is parenchymatous and 

 covered with hairs. A. L. S. 



Volutin, or the Metachromatic Bodies in the Yeast Cell. — AV. Hen- 

 NEBERG {Wocheiischr. Braiierei, 1915, 301-54, 1 tig. ; see aho Hediri(/ia, 

 1918, 60, Beiblatt, 25-6). Metachromatic bodies are recognized as those 

 that take stains in the yeast cells, and they are practically identical i\4th 

 "volutin" or " volutin-drops." The record is given of much experi- 

 mental work and of the conclusions reached. Henueberg is convinced 

 that volutin is the fermentation enzyme itself or the mother substance 

 of the enzyme, and cites in support of his view the rapid multiplication 

 of the " volutin-drops " during activity of fermentation. Volutin varies 

 in the different fungus cells, and it is hoped that a ready means of 

 identification will be found in the differences of staining. A. L. S. 



Fungi Imperfecti. — Franz von Hohnel {Hedwigia, 1917, 59, 

 236-84 ; 1918-19, 60, 129-209 ; 1920, 62, 56-80). the author has 

 prepared a complete account of Fungi Imperfecti to be published shortly. 

 He gives here descriptions of new species and critical notes on a large 

 number of forms. As new genera, based on species already described, 

 he publishes : Sderochseta (based on Phoma) ; SclerochseteUa (near to 

 Fyrenoc'haeta) ; Sderostagonospora (on Hendersorise Heradei) ; Rhizo- 

 sphserdla (on Perisporiitm Lentisci) ; Pleuronsema (on Sphseronsema 

 procumbeus) ; Sphseronsemina (on Sphderonaema cylindricum) ; Gerato- 

 phorna (on Sphseronsema rostratuni) ; ChondropodielJa (on Spliseroneema 

 rathrincolum) ; MycorhgndteUa (on Spseronema Betee) ; Gyanophomella 

 (on Plioma acervalis) ; Badrexciptda (somewhat similar to Stagonospora 

 Pint) ; Stidopatella (on Phyllostida destrudiva) ; Didymochora {Lepto- 

 .s^romac^ae), the pycnidial form of Euryacliora spp. ; Sderotliyrium [Conio- 

 thyrium, etc.) ; and Pseudodidiomera, the pycnidial stage of Cucurhitaria 

 spp. Full notes of these and many other members of the group are 

 contributed by the author. 



In a further contribution many more genera are passed under 

 review and one new genus diagnosed, Amphiciella, which forms small 

 stromata on dead leaves ; the spores are colourless, and one to three 

 septate. A. L. S. 



New Species of Melanotsenium, with a General Account of the 

 Genus. — Rudolph Beer {Trans. Brit. Mycol. Soc, 1920, 6. pt. 4, 

 331-43, 1 pi.). The author found the new species Mehinotaenium Lamii
