WebApr 24, 2011 · Pythium oligandrum is a eukaryotic organism. They were once thought to be a type of fungi, but they lack chitin and are made of cellulose, hence are currently categorized as a protist. Their oospores are spiny walled, which distinguished them from other species of Pythium. Their mature stage is multi-cellular and filamentous.
