third paper deals with Bolton's History of Fumjusses. The authors 

 discuss each plate and give their interpretation of the drawings. In 

 most instances they change the name : thus Agaricus campestris becomes 

 PsaUiota jJrato^s^s ; Agaricus latus, they find, represeots Pluteus 

 cervinus, etc. Tables are given of the old and the modern names.

Development and Dispersion of Spores in Coprinus sterqui- 

 linus.— A. H. Reginald Buller {Jahr. Wiss. Bot., 11)15, 56, 2i)'.)- 

 329, 2 pis., 2 figs.). The author finds that the sporophores of Coprinus 

 sterquilinus in the formation and dispersal of spores are similar to 

 those of C. comatus. There are no cystidia present, but thickened 

 projecting cells at the edges of the gills keep the lamellaj apart. There 

 are two tyj^es of basidia — long and short — and the spoies of the former 

 mature first. Stout paraphyses which separate the basidia occur in all 

 Coprinus species. A comparison is uiade with other Agarics aud with 

 other fungi. Spore liberation in Fuccinia, for instance, is not unlike 

 spore liberation in Hymenomycetes. A. L. 8. 



Thelephora terrestris, T. fimbriata and T. caryophyllea on Forest 

 Tree Seedlings. — James E. Weir {FhijtopiatlioJogy, 1921, 11. 141-4, 

 1 pi.). It has been known for some time that Thehphora terrestris 

 overruns and kills conifer seedlings by smothering them. During damp 

 weather the fungus grows quickly, and may envelop a small seedling in 

 a comparatively short time. It is not parasitic. The other two species 

 are also reported as causing the same trouble. A. L. S. 



Influence of Light on the Fructification of an Agaric in Pure 

 Culture.— Rene Maire {Bull. Sac. Hist. Nat. Afrique du Nord, 1919, 

 10, 94-lu(j, 1 pi.). The author gives a list of Hymenomycetes that 

 have been successfully cultivated. The Agaric he experimented with is 

 a Mediterranean plant, Fholiota cylindracea. He gives the results of 

 his various cultures of the fungus. It develops perfectly in complete 

 darkness. Direct white light prevents spore germination. Other lights 

 were also experimented with. Carpophores were formed in the laboratory 

 at seasons when none grew in the open. As transpiration and desicca- 

 tion have consideralile influence on development, these factors were 

 strongly influenced by the laboratory environment, and explained the 

 unseasonal growths. A. L. S. 



Rare Phalloid, Pseudocolus javanicus (Penzig) Lloyd. — Ch. 

 Bernard {Ann. Jard. Buit., 1921, 31, 93-lul, 4 pis.). The occur- 

 rence of a number of specimens of this " very rare Phalloid" at Tjiater, 

 in a forest of bamboos, enabled Bernard to make a thorough study. 

 The plant is so fragile that it disappears within a few minutes of its 

 birth. The volva is Itrown, sometimes very clear, and almost white, but 

 oftener a deep shade above ; the receptacle is red, and of a very bright 

 colour at the summit of the three or four arms, rose at the base ; the 

 gleba like that of other FhaUoidsse was greenish or almost black and 

 viscous ; the odour was strong and repulsive. Bernard gives a detailed 

 accouut of the tissues and reproductive parts, noting the points of dis-
