ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 417 



In another paper * the author describes a series of lichens collected 

 about the same time also by Vaccari in the Island of Lodi. They are 

 all saxicolous lichens. Zanfrognini has added various biological and 

 systematic notes on the different species. 



Fruit Development in Solorina.-f — Fernand and Mme. Moreau 

 pul)bsh an account of their research on the apothecium of Solorina. In 

 the first stages the upper cells of the gonidial hyphte form one or more 

 layers of short cells containing one or two nuclei, but mostly one only ; 

 these cells give origin to the paraphyses which grow up towards the 

 cortex. When the paraphyses have reached a certain stage of growth 

 ascogenous hyphai appear, also formed from the gonidial hypha^ ; the 

 cells are uninucleate, but the upper cells become binucleate and larger. 

 They spread out at the base of the paraphyses, and then produce the asci 

 at their tips or laterally, but there is no crook formed. In each ascus 

 two nuclei fuse, and spore-formation follows. There are only four 

 spores, but each divides into two cells. 



Lichens of Bermuda. J — Lincoln AV. Riddle publishes a list of all 

 the known species of lichens from this island. The collections on which 

 he has worked have been made at different times, and from them he has 

 secured thirty-six genera, with eighty-six species and varieties. Ten 

 of these species are new, and so far endemic. The new species are 

 crustaceous forms, with the exception of one Gollema. 



Mycetozoa. 



(By A. LoBEAiN Smith, F.L.S.) 



British Mycetozoa.§ — Two lists of Mycetozoa collected by members 

 of the British Mycological Society have been published, with notes. The 

 first, by W. B. Allen, contains the species collected at Baslow, Derby- 

 shire, in the end of May, 1915. A season of abnormal drought was 

 unfavourable to the growth and presence of these organisms. Among 

 the moi-e interesting finds were Lindbladia efusa^ new to Derbyshire, 

 and a variety of Trichia Botrtjtis, later described as var. cerift^ra in a 

 paper by G. Lister on Australian species. 



Mycetozoa of the Gower Peninsula. |1 — -The species included in the 

 list compiled by G. Lister were mainly collected during the autumn fungus 

 foray of the British Mycological Society to Swansea. The hunting- 

 ground included many mixed woods, and although no specimen of any 

 striking interest was collected, a very fair number — forty-seven in all — 

 was collected. Lamproderma arcyrlonema, on dead wood, was a new 

 record for Wales ; thoutrh widely distributed over the world it is un- 

 common in the British Isles.
