Some fungi take on different shapes, depending on their environmental conditions. These fungi are called dimorphic fungi , because they have “two forms.” For example, the fungus Histoplasma capsulatum , which causes the disease histoplasmosis, is thermally dimorphic; it has two forms that are dependent on temperature. In temperatures of about 25°C, it grows as a brownish mycelium, and looks like a mass of threads. At body temperature (37°C in humans), it grows as single, round yeast cells.
Consider the following text:
Two mycologists were studying fungi. Max studied regular fungi, while Red studied dimorphic fungi. They were both fascinated by their findings.

Which person learned more about fungi that take on different shapes?
