Abstract

A small proportion of sporangia of P. palmivora, less than 1.0 per cent, formed by hyphae growingon coooa pods germinated in humid air at 25°C whilst still attached to the hypha. to produce germ tubes terminated by seoondary sporangia. Sporangia in suspension in distilled water formed the greatest number of secondary sporangia at 30oe. Germination in samples of sporangia of the Sameage and formed under the same conditions varied, and, the percentage of directly germinated sporangia bearing seccndary sporangia at 30 0c ranged from 1.5 to 17.1 in the various samples.
