been chiefly examined with reference to temperature and to the 
rate of growth. The results of experiments are given in great detail.

Occurrence of certain Fungi in great Abundance after Forest 
Fires. — Leon Dufour {Bull. Soc. Mycol. France , 1922, 38, 93-7). 
The fungi that mainly appear on burnt soil are species of Discomycetes, 
Plicaria leiocarpa, Aleuria violacea, Geopyxis carbonaria , etc. The 
author considers one of the chief influences to be the letting in of light 
and air, and certain chemical modifications of the soil. These modifi- 
cations probably exist only a short time. A. L. S. 
Wood-staining Fungi. — B. D. MacCallum (Trans. Brit. Mycol. 
Soc., 1922, 7, 231-6, 2 pis.). The paper is concerned with the biology 
of blue-rot in timber or the blueing of pine wood. This is due to the 
action on the wood of species of Ceratostomella, a Pyrenomycete. 
MacCallum has investigated the life history of one of these, Ceratosto- 
mella Picese, and he concludes that the hyphomycetous stage is Graphium 
penicillioides. The results of the various cultures are f ully described. 
A. L. S. 
New Species of Fungi. — N. Patouillard (Bull. Soc. Mycol. 
France, 1922, 38, 83-7). A number of new species are described from 
various tropical countries east or west. The author gives a new genus 
of Nectriaceae, Eriospora, with one species, E. parasitica. It is distin- 
guished by the numerous small brown spores in the ascus. A. L. S. 
National Collection of Type Cultures. — R. St. John Brooks 
(Trans. Brit. Mycol. Soc., 1922, 7, 237-9). The writer has been 
appointed to the curatorship of type cultures at the Lister Institute. 
For some time bacterial cultures have been supplied to workers ; lately 
fungi have been added, and the writer indicates the kinds of fungi that 
are of value in such a collection, and their use to workers. A. L. S. 
Cases of Poisoning by Amanita pantherina. — E. Dalmier and 
Oliveau (Bull. Soc. Mycol. France, 1922, 38, 100-5). Three 
persons partook of the fungus, which was gathered in a mistake for 
Lepiota. The authors describe the symptoms of poisoning ; the effects, 
which lasted for several weeks, did not prove fatal. A. L. S. 
Poisoning by Dried Fungi. — J. Offner (Bull. Soc. Mycol. France, 
1922, 38, 116-8). The dried fungi were served in a restaurant at 
Grenoble, and seven persons were attacked with severe symptoms of 
poisoning, though not fatal. Some fungi lose their toxicity by drying, 
but not all of them. The whole matter is fully discussed. A. L. S. 
Symptoms of Wilting of Michaelmas Daisies produced by a Toxin 
secreted by a Cephalosporium. — W. J. Dowson (Trans. Brit. Mycol. 
Soc., 1922, 7, 283-6). The fungus grows on a watery medium in the 
form of a slimy sheet of mycelium, with the copious production of 
minute conidia. This medium was filtered, and into it were placed 
green shoots of Michaelmas Daisies. Mottling, paling and yellowing of 
the leaves took place, and the same results occurred in inoculation 
experiments with the Cephalosporium. Microscopic experiments were
