ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 245 



J. Ramsbottom takes occasion to describe it, and to give a sketch of its 

 history in botanical literature. It was first described and figured by 

 Thomas Woodward in 1784, from Bungay, Suffolk. Later it was found 

 on sand-hills at Stoke, Norfolk. The next record is by H. H. Higgins, 

 who found it in bare sand on the broken bank of a hedge near the 

 top of the hill, New Brighton, in 1857. It has since been collected at 

 Nork, near Epsom, and at Dropmore, Bucks. 



Fungi of New Guinea.* — Under the title " Fungi papuani " 

 H. and P. Sydow publish an account of the fungi collected in German 

 New Guinea by Ledermann in 1912-13. Among Basidiomycetes the 

 more woody genera, such as Polyporus, Stereum, etc., are best re- 

 presented, and include several new species. Ascomycetes are more 

 easily preserved, and are well represented with many new species. Two 

 new genera of " Fungi imperfect! " have been established : Sirosperma 

 (Sphseropsideje), with minute pycnidia on a felted substratum, and 

 parasitic on Hypocrella sp. ; and Sarophorwn (Hyphomycetes), with 

 olivaceous catenulate spores borne on sterigmata which are produced at 

 the ends of clavate hyphge. There^is one mycetozoon, Arcyria denudaia, 

 and oneHchen, Cora pavonia, in the collectiou. 



Mycological Notes.f — C. G. Lloyd gives with the present issue of 

 his notes a short account of the work of Von Schweinitz, along with a 

 portrait of this American fungologist. He was one of the pioneers of 

 mycology both in America and in Europe, where he worked along with 

 Albertini. 



Lloyd has a series of notes on very varied fungi. He still receives 

 and issues determinations and notes on Cordyceps. Along with Cordyceps 

 he figures a new species of Isaria (/. Buntingii) from W. Africa found 

 by R. H. Bunting on cocoons among fallen leaves. It is a very large 

 species ; the perfect Cordyceps has not yet been found. He has re- 

 ceived from Australia a specimen of Lycoperdon cruciatwn which is 

 common in the United States, but evidently very rare in Australia. 

 Among other unusual forms he figures pileate species of Meridius 

 lacrymans from Canada. Such a form is quite new, but Lloyd has no 

 doubt of the correctness of the determination. Most of the species dealt 

 with are figured. 



Black Spot of Chestnuts. I — ^B. Peyronel publishes a preliminary 

 account of his investigations of this disease of chestnuts. Outwardly 

 the chestnuts have the normal appearance, but when cut open the 

 blackish brown colour of the internal tissues is apparent. Peglion had 

 isolated a mycelium which he believes to be identical with Rhacodium 

 cellare ; it forms a black felt if the fruit is kept in moist conditions. 

 The mycelium cultivated on artificial media has produced conidia of 

 several different Hyphomycetes showing mixed infection. Bainier 

 meanwhile had succeeded with a pure culture of a fungus allied to
