Editing Hypha (section)

==Modifications==
Hyphae may be modified in many different ways to serve specific functions. Some [[parasitism|parasitic]] fungi form [[haustorium|haustoria]] that function in absorption within the host cells. The [[Arbuscular mycorrhiza|arbuscules]] of [[Mutualism (biology)|mutualistic]] [[mycorrhiza]]l fungi serve a similar function in nutrient exchange, so are important in assisting nutrient and water absorption by plants. [[Ectomycorrhizal extramatrical mycelium]] greatly increases the soil area available for exploitation by plant hosts by funneling water and nutrients to [[ectomycorrhizas]], complex fungal organs on the tips of plant roots.  Hyphae are found enveloping the [[gonidia]] in [[lichen]]s, making up a large part of their structure. In nematode-trapping fungi, hyphae may be modified into trapping structures such as constricting rings and adhesive nets. [[Mycelial cord]]s can be formed to transfer nutrients over larger distances. Bulk fungal tissues, cords, and membranes, such as those of mushrooms and [[lichen]]s, are mainly composed of [[felted]] and often [[Anastomosis|anastomosed]] hyphae.<ref>Moore, David.
