ZOOLOGY AND BOTANY, MICROSCOPY, ETC. C9 



Hijpnum cupressiforme srnd Fohlia nutans — namely, one or two thin 

 hollow pointed processes on the capsule ; also a bushy habit in Thuidium 

 abietinum, which is not due to Nematodes. 



Mosses attacked by Fungus.* — E. G. Britton gives a list of eight 

 mosses from the United States, Canada and Bolivia, upon specimens of 

 which the fungus Gladosporium epibryum was found growing, its black 

 septate hyphfe protruding from the walls of old capsules. 



Synopsis of Calymperes.f — G-. Roth publishes a synopsis of the 

 genus Gahjmperes. The last previous revision of the genus was made 

 by E. Bescherelle in 1906, and the characters which he relied upon^ 

 the taeniola and the cancelline cells — are, as M. Fleischer has shown, 

 rather artificial, and are variable like the leaf-form. But certain leaf- 

 types can be established, which occur especially on the young shoots. 

 Roth accepts in the main the divisions of Bescherelle's key, but 

 considers some modifications to be advisable. The sub-genera and 

 sections are as follows : — I. Somphoneuron Roth. II. Hyophilina CM. 

 (1. Stenocyda Besch. ; 2. Glimacina Besch. ; 3. Eurycyda Besch.). 

 III. Eticalymperes CM. (1. BimantinaJieiGh. ; 2. 3facrhimanta Hesch.). 

 The paper is a preliminary sketch of a descriptive and illustrated 

 monograph soon to be published. 



Haplomitrium Hookeri.J — E. Lilienfeld gives an account of Haplo- 

 mitrium Hookeri, in which the following points are brought out : — • 

 1. A new locality for the genus has been found in the Carpathians, and 

 the associated plants are enumerated. 2. The typical lateral arrange- 

 ment of the archegonia, extending to the lowest part of the stem, and 

 the agreement in the arrangement of the female and male reproductive 

 organs, o. The rhizomes, which have a formation like that of biological 

 humus-collecting nest-roots, show morphologically all transitions to the 

 green shoots. By want of light a large or complete reduction of leaves 

 is brought about in them. In their apical region occurs an abundant 

 development of mucilaginous clavate papillae, so close that they form a 

 pseudo-parenchymatic organ, which is biologically analogous, or perhaps 

 homologous, to the root-sheath. 4. In the cells of the rhizome there is 

 mostly a rich flora of parasitic and symbiotic fungi and aig?e, among 

 which the parasitic Pythium Haplomitrii is described. 5. The myco- 

 rhiza is generally present and differs from that of other hepatics, but 

 agrees with that of the Javan C'alobryi/m. Its characteristic is the 

 formation of single or numerous lumps in the cells, and these lumps 

 contain proteid and give a cellulose reaction in their superficial layers. 



Hepatics of Sussex. — W. E. Nicholson § publishes an account of 

 the hepatics of Susses. In the introduction he gives a sketch of the 

 morphology, reproduction, distribution, and literature of the group. 

 The list contains 124 species with their county distribution, with anno- 

 tations, and frequently with a careful diagnosis adopted from a modern
