Interactions of fungi at late stages of wood decomposition.

摘要: Species of wood-rotting fungi succeed each other during the decomposition a tree trunk; details this succession vary from to tree. Besides general pathways fungal decomposition, another and stricter kind exists. Over twenty species fungi, mostly polypores, were found inhabit such trees which previously decayed by certain species. The successor emerges only after preceding fungus has died, often fruits on dead basidiocarps previous one. Most predecessors occupy large volumes trunk. Fomesfomentarius (L.: Fr.) Fr., Fomitopsis pinicola (Sw.: P. Karsten, Hymenochaete tabacina (Sowerby: Lev., Inonotus Karsten Trichaptum Murr. serve frequently as Certain genera polypores include exceptionally many that have successional preference: Antrodiella Ryvarden & Johansen its close kin Junghuhnia Corda, well Skeletocutis Kotl. Pouzar related Piloporia Niemelâ. Fungi intimately depend are especially vulnerable deserve special attention in nature conservation. In most cases they survive virgin forests only, seem be rare also there. Even slight decrease abundancy may drastically suppress populations successor, or cause their disappearance.
