In this enclosure, we mainly observe hyphae, mycelial strands and sclerotia .
The black spheres on the images above are sclerotia, which form when hyphae aggregate. These sclerotia present a hard melanized black rind. Sclerotia serve as survival and reproduction and can survive for several years before germinating.
In this enclosure, we mainly observe mycelial strands and rhizomorphs. Note the fungal mycelial front where the mycelium form fan-like structures on the image below.
