1153. Putterill, VlCTOB Abmsby. Notes on the morphology and life history of Uromyces 

 Aloes Cke. South African .lour. Soi. 15:656 662. PI. Sg-SS,fig. 1 6. L919.— This is a brief 

 account of the common nisi attacking various Bpeciea of AUn m South Africa. A study was 

 made of the cytological development of the teleutospore, which is similar to that of other 



Uredineae. The occurrence of Bpermogonia is noted for t 1n- first t ime; t he nuclei of tlie sper- 

 matia occupy aboul one third of the diameter of the spore. The teleutospores germinate 

 readily, hut under no circumstances were sporidia obtained. The mode of entrance of the 

 fungus into the host was not ascertained. From the characters of the basidium of spores 



from various species of Aloe, it would seem that biological, if not true morphological varie- 

 ties of this fungus exist; this may account in pari, for the comparative immunity of some 

 species of Aloe growing in close proximity to badly diseased plants of other species. — E. .1/.

 new species of rust, Puccinia Corteyi Ran.] Bull. Trimest Soc. Mycolog. France 35: 140-141 . 

 / fig. 1919. — The author reports the collection of a rust on Heraclcum minimum, a new species 

 and names it Puccinia Corteyi after Cortey who collected the specimens in 1917. — Fred C.

1155. Raunkiaer, C. En ny Tulasnella-Art samt bemaerkninger om Tulasnella's sys- 

 tematiske Stilling. [A new species of Tulasnella with remarks on the systematic position of 

 the genus Tulasnella.] Bot. Tidskr. 36:204-209. Fig. 1. 1918.— A description is given of 

 Tulasnella helicospora n. sp. which forms a rather insignificant gray colored coating on moist 

 damp leaves, but later becomes more significant. A critical discussion is presented upon the 

 position of the genus Tulasnella. — A. L. Bakke.

 list of the fungi gathered during the foray. Trans. British Mycol. Soc. 6: 1-14. 1918. — A dis- 

 cussion of the important events associated with the foray includes the mention of interesting 

 species collected. — H. M. Fitzpatrick. 



1157. Re a, Carleton. New or rare British fungi. Trans. British Mycol. Soc. 6: 61-64. 

 PI. 2. 1918. — Lepiota fulvella n. sp., L. rosea n. sp., and Clavaria cinerea (Bull.) Fr. var. 

 gracilis n. var. are described and figured in colors. Notes are given on Boletus lacleus 

 LeV., Clavaria rugosa (Bull.) Fr. var. fuliginea Fr., C. chionea (Pers.) Quel., Geaster triplex 

 Jungh., Cyathipodia villosa (Hedw.) Boud., Humaria tetraspora [Fckl.) Boud., Dermatea 

 umbrina Cke. & Massee, and Antromyces copridis Fresen. — H. M. Fitzpatrick. 



1158. Scalia, G. Sull'Ascochyta pisi Lib. [On Ascochyta pisi Lib.] Staz. Sper. Agric. 

 Ital. 51 : 228-242. PI. 8, fig. 1-3. 1918.— From the study of abundant material of Ascochyta 

 pisi on beans and peas, examination of exsiccati specimens, and comparison of the diagnoses 

 of several Ascochyta species on Phaseolus and Vicita (A. fabae Speg., A. boltshauseri Sacc, 

 A. viciae Lib., A. vicicola Sacc, A. viciae-pisiformis Bubak, and A. viciae-lathyroides Syd.), 

 the author concludes that the species last named may be regarded as mere forms or varieties 

 of Ascochyta pisi. Since the morphological characters are extremely variable, the dimen- 

 sions of the pyenidia differing in specimens collected from the same plant, and the form 

 and dimensions of spores varying in a single pyenidium, separation into distinct species 

 on the basis of these characters is not justifiable. — E. K. Cash.

 organisms. Trans. British Mycol. Soc. 6: 17-31. 1918. — A brief discussion of some of the 

 well known phenomena of parasitism and symbiosis, with emphasis on the conditions in the 

 lichens. A bibliography of 31 references is given. — H. M. Fitzpatrick.
