American Spore Culture Mushroom Spawn 
Produced from Original Spore Cultures Under the New French Process 
The Most Prolific and Vigorous Spawn Known 
American Spore Culture Mushroom Spawn is described by 
the originator, as follows: 
‘ For a number of years attempts at spore germination have been 
made in this country, but more particularly in France, where the 
production of mushrooms exceeds that of any other country in the 
world. Until recently these experiments have resulced in failure or 
partial failure. The problems to be solved included (1) the gathering 
of the spores in pure culture (aseptically), ( 2 ) the germination of the 
spores under sterile conditions and (3) the successful development 
of the germinated spores into mycelium suitable for the manufacture 
of pure culture spawn. The first requisite was solved in various 
ways, the second was only partially solved, the methods devised 
giving only accidental or spasmodic results wholly unreliable for 
practical purposes; the third and most important requisite from the 
spawn-maker and mushroom grower's standpoint proved to be the 
most troublesome. It remained for a French scientist after years 
of research and exhaustive tests, which we have closely followed, 
to devise a working process by which spores can be gathered, ger¬ 
minated and propagated in pure culture with absolute certainty, 
in a remarkably short time, and with uniform results.” 
American Spore Culture Spawn is produced from original spore 
cultures under the new French process, which permits the indefinite 
reproduction of selected varieties without dilution of the strain, 
and free of any trace of the parasitic diseases of the mushroom. 
Positively the most vigorous and prolific spawn on the market.

“I purchased American Culture Mushroom Spawn from you ort March 1st. 
and picked the Mushrooms in the photo sent herewith on May 24th. I had some 
that weighed over )4, lb. each. Yesterday, the 5th of June , I picked a mess, 
and there are fully 100 buttons on the bed now. All this from a bed in the cellar, 
size 2 x 8 feet. J. A. COOK, Marshalltown, Iowa. 
“J bought some Mushroom Spawn, American Culture, from you last year 
and, although it was my first attempt, I had great success with it, raising over 
two pounds to a foot of space.” 
J. R. HALSTEAD, New Brunswick, N. J. 
“ The American Culture Mushroom Spawn recently purchased from you has 
started to show buttons all over the bed. It looks as if I am going to have as good 
luck with Mushrooms by using your Spawn as I have by using your seeds for 
the garden.” II. BARTHOLOMEW, Rockefeller, III. 
“Last year I purchased a small amount of your good Spawn, American 
Culture, and had splendid luck with it. On 88 square feet I raised 125 pounds 
of fine mushrooms which were of splendid flavor and color. My success has 
inspired me to try again on a larger scale.”
