Wie gross wird Heterobasidion annosum s.l.? – Eine Literaturübersicht | Clonal size of Heterobasidion annosum s.l.

We present a literature review on the size of H. annosum s.l.clones. As a rule, the largest diameter of a genet is smaller than 30 m, only in single cases up to 55 m were measured. The maximum age of an individual genet is estimated to around 200 years. The differences between the various intersterility groups and species within H. annosum s.l. are small. Potential factors which may delimit the mycelial life span are discussed.
