2050. BosE, S. R. Descriptions of fungi in Bengal, Series II, in continuation of Proc. 

 Indian Assoc. Cultivation Sci. Vol. IV Part IV (Agaricaceae and Polyporaceae). Proc. Sci. 

 Convention Indian Assoc. Cultivation Sci. 1918: 136-143. PL 1-13. 1920.— The following 

 species collected in Calcutta and its suburbs are described and figured (the figures show the 

 fruiting body above, below, and in section) : Lepiota mastoidens, Coprinus niveus, Volvaria 

 tirastins, Lenzites betulina, Polyporus gilvus, P. sp., Polijstictus versicolor, P. leoninus, P. 

 tabacimis, Fomes annularis, F. (Ganoderma) lucidus, Trametes cingulatus, Daedalea Hobsoni. 

 Most of the polypores reported were found on dead wood. The paper constitutes part II of 

 Bengal Polyporaceae, which is being published serially. — S. R. Base. 



2051. CosTAXTix, JuLiEX, ET Le6x Dufour. Sur la biologie du Goodyera repens. 

 [Concerning the biology of Goodyera repens,] Rev. Gen. Bot. 32: 529-533. 1920.— A fungus 

 isolated in a large proportion of the trials is regarded as a symbiont and is named Rhizoctonia 

 Goodyera repentis. — J. C. Gilman. 



2052. Dietel, p. tJber die Aecidiumform von Uromyces Genistae tinctoriae. [Concern- 

 ing the aecial state of Uromyces Genistae tinctoriae.] Ann. Mycol. 17: 108-109. 1919 [1920]. — 

 Observations made by the author on a field association of an Aecidium on Euphorbia cyparis- 

 sias with Uromyces Genistae tinctoriae (Pers.) Wint. on Genista tinctoria are recorded. These 

 observations strongly indicated a genetic connection between the two forms and an isolated 

 field culture was accordingly made which resulted in the development of uredinia on Genista 

 tinctoria following exposure to infection by aeciospores from Euphorbia cyparissias. The 

 aecial state belongs to the collective species Aecidiiun Euphorbiae Gmel. which causes defor- 

 mation of the host. Considerable variation exists in the character of the deformation in this 

 species and the author describes this in some detail in comparison with a description of the 

 case observed. There appears to be no correlation between the type of deformation in the 

 aecial host and the different species of Uromyces with which this aecidium has been previously 

 connected. — H. S. Jackson.

 Africa 8: 235-282. PL 13-19. 1920.— This is a systematic account of the South African 

 Microthyriaceae as represented in the Union National Herbarium. Fifty species are included 

 belonging to the following genera: Microthyrium (1), Seynesia (1), Morenoina (1), Englerw 

 laster (3), Parasterina (3) , Asterina (30), Asierinella (4), Lembosia{3), Echidnodes (l), Moren- 

 oella (1), Echidnodella (1), Amazonia (1). Theissen records only 6 species of Asterina from 

 Africa. The following new species are described : A . clausenicola, A . delicata, A . Excoecariae,

 im,plicata, P. rigida, Asterinella Acokantherae, A. Burchelliae, A. lembosioides, A. Woodiana, 

 Englerulaster Popowiae, Lembosia natalensis, L. radiata, Echidnodes rhoina, Microthyrium 

 maculicolum, Echidnodella Hypolepides, Morenoella Oxyanthae, Morenoina africana. A 

 host index is appended. — E. M. Doidge.

 wechsel und die Spezialisierung von Puccinia Caricis Reb, [Principal results of investigations 

 regarding the alternation of hosts and the specialization of Puccinia Caricis Reb.] Centralbl. 

 Bakt. II Abt. 50: 441-443. 1920. — A preliminary report of culture studies with Puccinia 

 Caricis giving an analytical grouping of the results based on the experiments of the author 

 and those of H. Klebahn, Numerous observations point to the conclusion that there are 

 biological forms in all groups studied. — Anthony Berg.
