No. 2, September, 1920] MORPHOLOGY AND TAXONOMY OF FUNGI. 255 



1950. Keene, M. Lucille. Studies of zygospore formation in Phycomyces nitens Kunze. 

 Trans. Wisconsin Acad. Sci. 19: 1196-1219. PL i 17 fig. i'.HO.— Cytological studies of 

 the plus and minus strains of Phycomyces nitens were made but no constant morphological or 

 cytological differences could be determined at any phase of the life cycle. The internal and 

 external changes occurring before and after conjugation are described and illustrated. Fol- 

 lowing a characteristic grouping of the nuclei, there appears to take place a fusion of nuclei 

 in pairs. The disorganization of part of the nuclei, probably the unfused ones, is followed by 

 the appearance of reserve substances: a large amount of oil and a nucleo-protoin-like sub- 

 stance. — L. K. Bartholomew.

 Eigene Untersuchungen. [Perfect and imperfect stages of ascomycetes.] 395 p., 275 fig.

1952. Latham, Roy. Musci hosts of Cyphella muscigena Fr. Bryologist 23 : 7. 1920. — 

 The author notes that in Southold, New York, the fungus seems to prefer Thuidium paludosum 

 as host to the exclusion of other, intimately associated species. — E. B. Chamberlain. 



1953. Leidy, Joseph. Modification of Gram's stain for bacteria. [Abstract.] Absts. 

 Bact. 3: 7. 1919. — "In the course of some experiments in staining bacteria according to 

 Gram's method it was found that any of the metallic iodides soluble in water may be substi- 

 tuted for the potassium iodide in Gram's (Lugol's) solution." [From author's abstract of 

 paper read at scientific session, Soc. Amer. Bact.] — D. Reddick. 



1954. L'Estrange, W. W., and R. Greio-Smith. The "springing" of tins of preserved 

 fruit. Proc. Linnean Soc. New South Wales 43: 409-414. 1918.— Cans of pears and plums, as 

 compared with apricots and peaches, were found to be especially susceptible to "springing." 

 Yeasts chiefly, certain moulds and bacteria sometimes, apparently in an inactive condition, 

 were found. Suggestions for better operating methods are given. — Eloise Gerry. 



1955. Lloyd, C. G. Mycological notes. No. 57. P. 830-844, fig. 1388-1412. Cincinnati, 

 Ohio, April, 1919. — A photograph of J. Ramsbottom is accompanied by a brief personal 

 appreciation. The status of the genus Laschia is discussed, and about twenty species are 

 cited with annotations. Under the heading "rare or interesting fungi received from corre- 

 spondents" the following are discussed and in most cases figured: Clathrus cancellatus, Len- 

 tinus rivulosus, Hydnum pule her rimum, Dacryomiira depallens, Polystictus pinsilus, Dacry- 

 opsis nuda, Polystictus felipponei, Polyporus greenii, Polystictus scopulosus, Podocrea xylari- 

 oides. — H. M. Fitzpatrick. 



1956. Lloyd, C. G. Mycological notes. No. 58. P. 814-828, fig. 1358-1887. Cincin- 

 nati, Ohio, March, 1919. — A short account of Arthur Lister's life and work is accompanied 

 by a photograph of this well known student of the myxomycetes. The following "rare or 

 interesting fungi received from correspondents" are discussed and in most cases figured: 

 Campanella cucullata, Durogaster brunnea, Rimbachia pezizoidea, Geaster tomentosus, Trem- 

 ella mellea, Polyporus smaragdinus, Porodiscus rickii, Polystictus hexagonoides , Favolus 

 caespitosus, Pterula fruticum, Daldinia albozonata, Polyporus setiger, Polyporus alrohispidus, 

 Lentinus chordalis, Guepinia elegans, Dacryomyces pallidus, Tremella compacta, Dacryomitra 

 dubia, Stereum corruge, Polyporus pertusus, Lachnocladium braziliense, Dacryomyces hyalinus.

1957. Lloyd, C. G. Mycological notes. No. 59. P. 846-860, fig. 1413-1448. Cincinnati, 

 Ohio, June, 1919. — A good likeness of George F. Atkinson appears on the cover of the pam- 

 phlet. A short personal appreciation accompanies it. The genus Trichoscypha is discussed 

 and three species are described. These are T. insititia, T. hindsii, and T. Tricholoma. 

 The following fungi are discussed and in many cas'es figured: Trametes heteromorpha, Tra- 

 metes sepium, Trametes serpens, Tremella Candida, Irpex caespitosus, Lenzites betulina, Cata-
