Boergesen, and H. F. A. Eggers. One hundred and eleven new species are de- 

 scribed and also a considerable number of new varieties. Important synonymy 

 is indicated and there are some nomenclatorial changes. The generic affinities 

 of the new species are as follows: 12 in Gr aphis (including Graphina, Phaeo- 

 graphis, and Phaeographina); 11 in Pertusaria; 9 each in Buellia and in Arthonia 

 (including Artholhelium and Allarthothelium); 7 in Porina; 5 each in Placodium 

 (Caloplaca, Blastema), Thelotrema (including Leptotrema and Ocellularia) , and 

 Pyrenula (including Melanotheca); 4 in Arthopyrenia; 3 each in Parmelia, Rin- 

 odina, Lecidea (including Catillaria and Lopadium), and Chiodecton; 2 each in 

 Lecanora, Pyxine, Leptogium, Collema, Pyrenopsis, Psorotrichia, Thelenella (in- 

 cluding Microglaena), and Pseudo pyrenula (Trypelhelium) ; one each in Usnea, 

 Etimitria {Usnea), Physcia, Peltigera, Pannaria, Coccocarpia, Physma, Synal- 

 issa, Lecanactis, Spirographa, Opegrapha, Bottaria {Anthracothecium) , Pyrenas-

NOTES ON CURRENT BRYOLOGICAL LITERATURE 



In a recent issue of the contributions from the National Herbarium, Dr. 

 Evans^ published a monographic treatment of the genus Asterella (Ftmbriaria), 

 recognizing 15 species, and discussing five doubtful ones. The paper includes 

 a historical introduction to the genus, nine pages of morphological notes, and 

 a full description of all species known to occur in North America, with their 

 exact distribution, in the latter including extra-limital ranges. Asterella saccata 

 (Wahl.) Evans and A. venosa (L. & L.) Evans are new combinations, and A. 

 rugosa Evans, A. reticulata Evans, and A. versicolor Evans, are proposed as new 

 species. 



In the last two issues of Broteria to come to hand. Father Luisier^ con- 

 tinues his catalogue of the Maderian mosses, covering the genera Orthotrichum 

 to Thamnium. The accompanying plate figures species described in the pre- 

 vious, fourth, article of the series, the present ones being the fifth and sixth. 

 There are no new forms described, but many valuable discussions are given 

 under the individual species, as well as reprints of original descriptions and 

 material from works difificult of access. Special note should be made of the 

 treatment of UIom calvescens, Funaria Fritzei, Pohlia proligera, Br yum serru- 

 latum, Pogonatum subaloides, Neckera intermedia, and of the genera Haplodon- 

 tium, Leucodon, Brachymenium, and Echinodium. 



The two issues of the Revue Bryologique, noticed elsewhere in this issue, 

 which make up the end of the forty-first volume, contain the conclusion of Mr. 

 Ingham's Catalogue of the Mosses and Hepatics of the Magnesian Limestone
