Lachnellula willkommii is a fungus that attacks Larix decidua. The fungus does not kill the tree, although in some cases , but it does inhibit growth (Pãques et al. 1999). The potential for L. willkommii to damage in North America is high and this has caused state and federal agencies to issue flyers to the public to warn and tell people to be cautious when trasporting cuttings or seedlings (Campbell, 2004).
