Twelve localities are known in nature (open forests) in Czechoslovakia for the dry-rot fungus, Serpula lacrymans (Wulf. in Jacq.: Fr.) Schroet. It grows mostly parasitically on the roots and bases of living Norway Spruce (Picea abies) but, in a few cases, is also saprophytic on dead, fallen trunks, branches or stumps of spruce. All other observations and finds in this country of this otherwise frequent fungus are within houses and other buildings.
