 Heterobasidion annosum

[Description]

H. annosum sensu stricto, H. parviporum and H. abietinum are close relatives and show only small differences in morphology, although they have not yet been thoroughly investigated. It is usually relatively easy to distinguish between H. annosum and H. parviporum on the basis of basidiocarp morphology: H. annosum has large pores and the brown upper surface is hard, whereas H. parviporum has small pores and the brown upper surface near the margin looks soft and velvety (tomentose) when viewed under a magnifying glass. Identification of H. abietinum is more difficult as these characteristics are somewhere between those of H. annosum and H. parviporum (Mugnai and Capretti, 1989). Accurate identification of these three species is often only possible in the laboratory.

A detailed description of morphology exists only for H. annosum sensu lato.

[Distribution]

Although precise identifications are lacking, H. annosum sensu stricto probably exists everywhere in Europe where Heterobasidion occurs in pine forests, i.e. in almost all European countries. The northern limit of distribution in Scandinavia is ca 63°N. In the east, the distribution of H. annosum sensu stricto probably extends over southern Siberia, but it has not yet been found in eastern Asia.

North American records in the distribution list refer to the 'North American intersterility group P' or 'pine group' of H. annosum sensu stricto. The North American P group probably occurs in all states where H. annosum sensu lato has been recorded, excluding perhaps Alaska, and appears to be the only intersterility group of H. annosum occurring in eastern parts of the continent.

[Hosts/Species Affected]

H. annosum sensu stricto mainly affects species of Pinus, but it also affects a wide range of other conifers in Europe. It is found relatively often on dicotyledonous hosts when they grow in mixture with a susceptible conifer species. It primarily inhabits pine forests and plantations of other conifers established on sites with pine history. It is rare or absent in eastern Asia. Many of the hosts listed have been recorded in the UK, where only H. annosum sensu stricto has been found.

The North American P group affects mostly species of Pinus in North America. The following hosts have only been recorded for the North American P group: Libocedrus decurrens, Arctostaphylos sp., Calocedrus decurrens, Juniperus occidentalis, Picea engelmannii, P. rubens, Pinus coulteri, P. elliottii, P. jeffreyi, P. lambertiana, P. monophylla, P. ponderosa, P. resinosa and P. taeda.},
