GODDARD, H. N., Soil Fungi. A preliminary report of fungi found 
in agricultural soil. (Thirteenth Report of the Michigan Academy 
of Science, 1911, 208—213.) 
The proposes of this study are 1. to determine what species of fungi 
live habitually in an ordinary agricultural soil; 2. to ascertain their des- 
tribution as to depth, and to kind and treatment of soil; 3. to find what 
part they take in soil fertility. The results of the last are reserved for 
a future paper. 
A plat of rather rich clay loam, having a liberal amount of sand 
was chosen for investigation. Samples of this soil were taken and cultures 
made by the usual plating method. From these, pure cultures were iso¬ 
lated and studied. The growth of bacteria was inhibited by adding a large 
per cent of gelatin to the medium. The species found so far are: Mucor - 
sp Myceliophthora sp., Fus arium-Cephalosporium sp., Acrostalagmus cinna- 
barinus , Pachybasium hematum, Aspergillus calyptratus, A. nidulans, 
A. glaucus, Pénicillium glaucum , P. bicolor , P. candidum , P. humicola, 
Hormodendron cladosporioides, Stysanus stemonides. The following gene¬ 
ralisations are arrived at. These fungi exist habitually in the soil and 
carry out at least a part of their work and respective life histories in this 
habitat. This flora is to a conspicuous degree, constant in different soils, 
and also, rather uniformly distributed at all depths, at least as low as 
14 cms. Tillage and manuring, so far as observations at present show, 
seem to produce little change in the number and kind of species present. 
This statement in based on a study of samples taken from a manured 
plat, three months after the manure was applied, so that the fertiliser 
had become well decayed and mixed with the soil. Many of the fungi 
show striking variability in their structural characters, when cultivated on 
media of constant composition. One form which shows the structural 
characters of both Fusarium and Cephalosporium , is the probable cause 
of a destructive wilt disease which attacks several species of garden flowers, 
Aster , Sweat-pea etc. J. Ramsbottom (London).
