Moulds and indoor climate in Denmark
2003 - IRG/WP 03-10488
Just like in many other countries after the oil crisis in 1972 Danish houses were tightened with the result that the relative air humidity rose considerably. The Ministry of Energy also demanded a lowering of the indoor temperature from 25°C to 20°C with the result that the relative air humidity rose even more. According to the latest survey 10% of Danish buildings are infected with moulds. Moul...

Quality control of microwave treatment of timber after dry rot attack
2001 - IRG/WP 01-40205
In Denmark microwave treatment of timber has been used during the last 15 years for eradication of dry rot (Serpula lacrymans). About 1500 microwave treatments have been employed in coorporation with Hussvamp Laboratoriet. Previously all the infected timber was removed plus an extra metre as a safety zone. This meant that all casting boards and plaster had to be removed as well and joists replaced...

Copper-resistant fungi on pressure impregnated wood in Denmark
1994 - IRG/WP 94-10078
The occurence of Amorphotheca resinae Parbery and its asexual stage Cladosporium resinae (Lindau) de Vries on CCA and CCB treated wood has previously been shown. In the autumn 1993 some other blue stain fungi were found on CCP and CCB treated pine timber, such as Ophiostoma minus (Hedgc.) H. and P. Sydow, Ophiostoma pilifera (Fr.) H. and P. Sydow and Ophiostona piceae (Munch) H. and P. Sydow. The ...

The dry rot fungus (Serpula lacrymans) in nature and its history of introduction into buildings
1999 - IRG/WP 99-10300
For many years the True dry rot fungus (Serpula lacrymans (Wulf.: Fr.)Schroet.) has exclusively been found in buildings. That is why it is called the True dry rot fungus. The origin of the fungus has always been a mystery, but a wild ancestor must have occured. In the literature there is some information about finds of Serpula lacrymans in nature, however it is difficult to distinguish it from the...

The true dry rot fungus (Serpula lacrymans) as a wound parasite of living Norway spruce (Picea abies) in the Czech Republic
2001 - IRG/WP 01-10389
Some late 19th century Central European mycologist reported finds of the true dry rot fungus (Serpula lacrymans) from nature. They even suggested that it could be a parasite of living trees. However examination of herbarium material has shown that the species they found was thin-fleshed dry rot (Serpula himantioides) rather than Serpula lacrymans. In 1992 the Czech mycologist Kotlaba reported find...

On the biotope of dry rot (Serpula lacrymans) in the wild
1995 - IRG/WP 95-10123
The True Dry rot fungus was found in the Himalayas several times in this century. The finds were able to cross breed with Serpula lacrymans from Denmark and therefore all belong to this species (Harmsen 1960). In order to understand its successful colonisation in buildings we were interested in studying the natural biotope, i.e. the moisture, temperature and soil relationships. All together 15 fru...
