Dikaryon (dicaryon) A fungal hypha or mycelium whose cells each contain two different nuclei, arising from the fusion of two compatible cells, each with one nucleus.
Reproduction in lichens may be asexual by soredia (algal cells enclosed by fungal hyphae) or by sexual fungal spores, which can survive only if some algal cells are also present.
A handful of soil has several thousands worm individuals and other kinds of creatures and thousands and millions of bacteria and kilometers of fungal hyphae.
Previous research has suggested that fungi conduct electrical impulses through long, underground filamentous structures called hyphae – similar to how nerve cells transmit information in humans.
