Mycelium, the vegetative part of fungi, does not require light to survive. It primarily relies on decomposing organic matter for its nutrients and energy. However, light can play a role in the growth and development of some fungi, influencing the formation of fruiting bodies (mushrooms) and their direction of growth. But overall, mycelium can survive and grow in the absence of light.

Is mycelium affected by light? ›The effect of light of the tested mycelium has a significant effect on the content of bioactive components in oyster mushrooms.
How does mycelium survive? ›Mycelium secretes enzymes to break down complex organic molecules from things like branches, leaves, dead bugs, animals, etc. into digestible nutrients that the mycelium can absorb and use to grow. Since few other organisms are adapted to use these food sources, this is a great strategy for getting energy.
What is the lowest light level mycelium required to spread? ›A mycelium block can spread to any dirt block within one space above, one sideways, or three down. The mycelium needs light level 9+ above it, while the dirt needs light level 4+ above it, and must not be covered by any light-impeding block or any opaque block.
Can mycelium grow in dark? ›Mycelium grows just fine in a dark place, and some daylight does not matter. Do not place the mycelium in direct sunlight, this will heat the substrate and it could dry out faster.
Do fungi need light to survive? ›And while many fungi actually live in sunny spots, they don't need light in the same way that plants do. Unlike plants, fungi don't photosynthesize—they don't use chlorophyll to convert light into chemical energy. Light, then, isn't their primary source of food or energy.
