Guide to Sowerby’s Models of British Fungi in the British Museum 
( Natural History ), by Worthington G. Smith. 
This u guide ” is not a mere catalogue of names, but serves as 
an introductory text book ; there is a brief introduction to the 
study of fungi, the necessary technical terms are explained and 
made quite clear by the aid of diagrammatic sections. In what 
may be termed the systematic portion, all the species illustrated by 
models exhibited in the Botanical Gallery are described, and their 
properties, edible, poisonous, etc., are also noted. The numerous 
figures interspersed in the text will be found of great value to 
those commencing the study. The slip on p. 6 respecting the 
origin of the spores in the Lycoperdaceaz will require attention in 
a second edition. 
Kulturversuche mit heterocischen Uredineen. (Culture experi- 
ments with Heterocismal Uredines.) H. Klebahn, Zeitschr. fiir 
Pflanzenkr., II. Bd., 5 u., 6 Heft, p. 1(1 ph.). 
The cultures and results recorded in the present paper are of 
value to those specially interested in the heterocismal Uredines, 
although to the outsider there always appears the great necessity 
for a considerable amount of faith in addition to the evidence 
forthcoming. 
The fact that hetercecism exists very few persons deny at the 
present day, but at the same time demonstrable evidence is by no 
means easy ; for instance, has either friend or foe of the theory' 
ever corroborated De Bary’s observation relating to the piercing of 
the epidermis of the barberry leaf by the germinating promycelial 
spores of Puccinia graminis. 
Among other things are two new species of Peridermium, P. 
Plowrightii (Kleb.) ,—Coleosporium tussilaginis (Pers.), and P. 
Stahlii (Kleb .)=Coleosporium euphrasies (Schum.). 
The relationship between a Puccinia on Phalaris and AEcidium 
convallarice , first pointed out by Soppitt, has been corroborated ; 
the Puccinia is probably P. digraphidis, Soppitt, although the 
teleutospores only measure 32-41 x 15-18 p. 
Fungi AEthiopico- Arabici. P. Hennings, legit. G. Schwein- 
furth, Bull, de l’Herb., (Boissier), I., p. 97 (1893), 2 pi. — Many 
new species are described and figured. Guepinia fissa (Berk.) is 
a very variable species, and shows a sequence far wider in habit, 
size, and form than the new var. Abyssinica (P. Henn.), as 
described and figured. 
Sphcerophragmium Dalbergice. — Ur. Dietel has described under 
the above name a new Sphserophragium, parasitic on Dalbergia 
armata , from Inanda, Natal (Hedw., 1893, Heft 1, p. 30).

Dr. Thaxter has described what appears to be a very remarkable 
new order of Schizomycetes, some of the members having pre-
