METHODS OF SPORE DISPERSAL 
persal, and probably in this way many Continental species 
are introduced into Britain. 
That many species of fungi are brought from one conti¬ 
nent to another by human agency—often upon imported 
seeds and plants—will occur to all my readers. In this 
way only too many obnoxious kinds have been introduced 
into this country, chiefly from America, I believe. Massee 
records that “ many kinds of foreign fruit examined at Kew 
have furnished fungus spores which have germinated readily, 
and which, if they had found their way to the proper host- 
plant, would undoubtedly have established a disease.”*
