approximately at the same altitude, warrants the conclusion that hey

A PECULIAR CASE OF SPORE DISTRIBUTION. 
(WITH FIGURE I.) 
THE manner in which the spores of fungi may be distribute 
clearly shown in a case which came under observation last Septem 
in Columbus, Ohio. A grape vine, quite thoroughly infested with 
mildew, Uncinula necator (Schw.) Burr., showed its characteristic ® 
cular spots in profusion. This was the condition over about two-th 
of the one affected vine, and the appearance of these leaves is shown™

examination proved the fungus to be identical in the two cas!

white mycelium and conidia plainly mark the track.
