Resúmenes
Germination of Crinipellis perniciosa basidiospores and host infection occurred when spores were deposited on wet cacao flushes and wetness was maintained for a minimum of 4-6 hr. Basidiospores deposited on dry plant surfices plasmolyzed. Basidiospore germ tube tropism towards stomata and the base of fallen or collapsed multicellular trichomes was observed. Host penetration and subsequent formation of subepidermal vesicles occurred within 12 hr after inoculation. Intercellular hyphae developed from subepidermal vesicles in some infection sites while in others the pathogen failed to colonize host tissue. This failure was associated with a change in fluorescence of host cells at and around the infection site
