1. Damage-picture from the dry rot Serpula lacrimans
Form 1: Brown die-break, approximately like sugar-dice big, breaks crosswise to the fiber
The brown-rottenness (Destruktionsfäule) is characteristics. This fungus has at the degradation of cellulose specialize. This remains Lignin, which does a brown look have. Injured party wood has cubical dice at wood-surface with usually 2 cm of crust-length. The die-fragility is dark brown until shining.
Form 3: House-sponge in the doorframe, curvature of the boards.
The real house-sponge is purely one, it attacks saprotropher fungus, that is called, dead and obstructed wood.
Destruktionsfäule: By the degradation of the cellulose of the wood, the reason-structure of the wood is destroyed. The brown lignin remains. Rips are created in the wood to the barrel-erection crosswise. The wood loses solidity and it can derive no more the strengths.
Form 5: Here, an old fruit-body (2) with dark spores is on the picture, an again respectively vital fruit-body (1), to recognize with white increase-fringe and Myzel with small fruit-bodies (3) (need-fruit-bodies).
