Mold-hunting expedition
A mold-hunting expedition was how Tom Paris described his and Neelix's 2376 trip to a planetoid in the Wyanti system. Their task was to locate a spore that The Doctor wished to grow antiviral proteins from. 

Paris sarcastically remarked " I tell you, Neelix, when I first joined Starfleet I knew it was going to be one glamorous adventure after another, but I never dreamed that I'd have the opportunity to go on a mold-hunting expedition." ()
