👉 Ducelliers are a group of plants that produce seeds similar to those found in the genus Penicillium, but with an unusual morphology and reproductive system. They possess the ability to form colonies on the surface of soil or water, which is often referred to as "doubling up" like penicillium. This unique property allows them to colonize environments where other organisms do not thrive, such as in arid regions or in areas with limited access to sunlight and nutrients.
