A reference to a sticky or viscid (gooey, slow-moving) consistency that takes place during rainy periods; especially, the fungal caps; such as, the tops of mushrooms or other kinds of fungi: Right after the downpour, Janet and her husband went for a walk and noticed the toadstools under the pine tree in their back yard which not only had pluviovisid tops, that were quite shiny, but they were also glutinous or thick and sticky when touched.
