4. Description of further types of the dry rot

Serpula lacrimans var. himantioides (Fr).:Fr.) - Wild dry rot (= Merulius silverster Falck).
It possesses less destruction-strength than the real dry rot and is relatively rare. The temperature-optimum is with 24 to 27ºC for it. It grows at softwood-stumps and obstructed softwood mainly outside. In buildings, it more rarely occurs. The fruit-bodies are thinner, without bulge-y fringe and never forms brackets. The mycelium becomes only twine-thick.

Leucogyrophana pulverulenta (Sow).: Fr.) Ginns - small dry rot, in great commissures living or small sporiger drey rot (also Serpula minor, Serpula tignicola, Harmsen) of Christian
It occurs predominantly in buildings that however, the destruction-strength of Serpula lacrimans doesn't have. Has smaller spores and white mycelium-cords. The fruit-bodies are daintier and gain a diameter of Max. 15 cm. The thickness becomes 1 to 2 cm approximately, is very flat and has a white fringe. Optimal growth-temperature 18 until 22ºC. Softwood attacks predominantly.

Leucogyrophana mollusca (frieze 1821) Pouzar - Sklerotien drey rot also Kiefernfältling, Leucogyrophana pouzarii Parm.

Leucogyrophana pinastri (Fr.: Fr.) Ginns & Weresub, Serpula pinastri, Fr.:Fr.)W.B.Cooke.- Sklerotien-dry rot or Gelbrandiger-drey rot
Also a brown-rottenness-fungus is at obstructed wood (predominantly softwood), but with us only very rare. It asks for higher initial-humidities of the wood, however, serious loss can prepare at its appearance. The fruit-bodies can gain a diameter of 15 to 20 cm. The thickness hardly reaches 5 mm. The Myzel is cream colorfully until sallow-gray and much thin. The fiber-hyphas are missing in the sallow-brown cord-mycel.

Serpula eurocephala
grows on living and dead bamboo and can prepare quite big damage in the tropics at obstructed bamboo. These types are adequate in South America's tropics, Africa, for Asia and Australia.
