 1919. — Ten years have elapsed since the publication of the first edition of the "Guide to the 

 British species of Mycetozoa." In the preparation of a new edition changes in nomenclature 

 were required to make it agree with the second edition of the "Monograph of Mycetozoa" 

 published in 1911, and also much new information was incorporated. Five genera, 35 species 

 and several varieties have been added to the British list. Notes on the occurrence, discovery, 

 nomenclature, and morphology of these species and varieties are given. Physarum vernum 

 Somme, var. iridescens is described as new. — K. M. Wiegand. 



1134. Lloyd, C. G. Letter, No. 69. 16 p. Apr. 1919. (Cincinnati, Ohio.)— This letter 

 includes the usual acknowledgment of specimens received and miscellaneous notes on a wide 

 variety of fungi, particularly Polyporaceae. A special request is addressed to friends and 

 correspondents asking that fungi be sent to the Lloyd museum. The forms most desired 

 are tremellaceous fungi, Pyrenomycetes and Discomycetes possessing a large fruit-body, 

 Clavarias, Thelephoraceae and Gasteromycetes. A review of Kauffman's "Agaricaceae of 

 Michigan" is appended. — H. M. Fitzpatrick.

 sites. — Fred C. Werkenthin. 



1136. Mulvania, Maurice. A comparison of azotobacter with yeasts. Tennessee Agric. 

 Exp. Sta. Bull. 122. 6 p. 1919. — A direct comparison is made of the morphological and physi- 

 ological characteristics of twenty-five strains of Azobacter with two species of yeasts. The 

 tables presented show a striking similarity between all the organisms studied, and it is con- 

 cluded that they are all members of a "narrowly restricted group of organisms." Among the 

 striking features of resemblance are noted the presence of a nucleus and reproduction by buds 

 in both yeasts and Azotobacter. These are said not to be met with among bacteria in general. 

 The spores of Azobacter resemble spores of yeasts rather than bacteria in regard to heat re- 

 sistance. — Maurice Mulvania.

 Botanist, 1917.) New York State Mus. Bull. 205-206: 67-166. PL 1-23. 1918.— About 20 

 species of resupinate pore fungi described by Peck are studied microscopically, each species 

 being treated in four sections: (1) Peck's original description; (2) Notes on the present condi- 

 tion of type material, on characteristics not mentioned by Peck, on explanation of discrep- 

 ancies, on characteristics and probable relationships of species; (3) Redescription, i.e., a com- 

 bination of the material presented in sections 1 and 2; (4) Illustrations. Each species is 

 illustrated as fully as the material permits, three types of illustrations being used: (a) Natural 

 size photographs of type material, (b) Photomicrographs of free-hand sections of the hy- 

 menium. (c) Line drawings of spores and hyphae with the aid of camera-lucida. The fol- 

 lowing species are treated: Poria attenuata (Pk.) Cke., P. attenuata var. subincarnata Pk., 

 P. aurea Pk., Daedalia extensa Pk., Poria fimbriatella (Pk.) Sacc, P. griseoabla (Pk.) Sacc.
