after three months they were only tangled masses of hyphae, and after 
five months they had formed neither selerotia nor fruiting bodies. 
In cultures on gelatin and on bread, beads of water appeared. Growth 
was cottony, snow-white at first, later peach-bloom red, changing to 
yellow, which finally disappeared. Conidia and mycelial concretions 
were formed. 
^The species isolated from buds of the Georgia peach resembles very 
closely Fusarium gemmiperda Aderhold and will be considered as identical 
with it. This species on rare occasions produces chlamydospores (fig. 
1, C), but the writer grew the fungus on artificial media for two years 
before he found any of them. The peach-bloom red is not so evident as 
with Aderhold’s fungus. The extreme length of the conidia is greater, 
but if one considers only triseptate conidia, since they predominated in 
Aderhold’s cultures, then the measurements of the two correspond very 
closely. The form from Georgia peach buds has conidia typically sickle 
shaped (pi. 1, B), sometimes distinctly broader in the upper third, rather 
suddenly constricted at the apex and often so at the base, 3 septate or 5 
septate forms predominating (fig. 
1, A and B). Aerial hyphae may 
be present, 2 to 8 mm. high, or 
nearly absent; when absent, pseu- 
dopionnotes are abundant; when 
present, sporodochia are usually 
formed. Chlamydospores are 
rarely found. Color of aerial 
mycelium is white; color of pseu- 
dopionnotes is pale pink to cream, 
changing to brown when old. 
Sporodochia (pi. 1, A) on peach 
bud scales are white, in cultures 
from white to salmon pink. Co- 
nidiophores may be nearly lack¬ 
ing, being scarcely more than 
swollen places along the myce¬ 
lium or they may consist of

numerous branches coming out at adjacent points along a hyphal filament. 
Cream-colored selerotia may be present, especially on potato plugs. 
On bud scales of peach 3 to 5 septate conidia were found in large 
numbers; sometimes the former, but more often the latter, predominat¬ 
ing. On commeal agar sometimes 3 and sometimes 5 septate conidia 
predominate regardless of age. On beef agar, potato agar, and potato 
plugs, 3 septate conidia are usually present in much larger numbers than 
5 septate conidia. On 4 per cent potato agar often all are 3 septate. 
Conidia! measurements are as follows: 
Conidia from 30 days’ old corn-meal agar: 
3 septate, 32-46 x 4-5, average 36 x 4.5. 
4 septate, 42-53 x 4.5, average 47 x 4.5. 
_ 5 septate, 46-61 x 4.5, average 51 x 4.5. 
Conidia from 20 days’ ola potato plug: 
2 septate (only 1 measured) 25 x 5, average 25 x 5. 
3 septate, 29-46 x 4-5, average 38 x 5. 
4 septate, 38-59 x 4-5, average 46 x 5. 
5 septate, 42-63 x 4-5, average 55 x 5.
