Although blue stain fungi do not cause decay of wood, they lower the quality of wood and wood products (Fig. 1). In the pulping process, blue stain reduces pulp brightness, which leads to significant increases in the... 

The two most important aspen blue stain fungi are Ophiostoma crassivaginatum and O. piliferum. The secondary metabolites of the blue stain fungus O, crassivaginatum were studied in an attempt to obtain insight into the nature of the staining material. Several simple phenolic compounds were identified which, at least in part, can be responsible for the discoloration of aspen wood infected with this fungus (72). 

An unidentified Zythiostroma species, isolated from aspen, was also found to be antagonistic to O. crassivaginatum. Zythiostromic acids A (25) and B (26), as well as zythiostromolide (27) isolated from the culture broth of this fungus, although new natural compounds, were inactive against the blue stain fungi (16) (Chart 5). 

Lecythophorin (29) shows very good activity at 1 pg/ml against the blue stain fungi (20), but the fact that the fermentation yield is very low and synthetic preparations of this compound will, presumably, not be possible on a commercial scale, precludes the use of this compound in the field.

Resinosis - the abnormal flow of resin - is considered the most important factor contributing to the resistance of lodgepole pine to bark beetles (Dendroc-tonns) and blue-stain fungi, but stilbenes also may be involved. Wound-response tissue from resistant trees attacked by Dendroctonns ponderosae and its associated microorganisms contained approximately twice the level of pinosylvins 5 weeks after attack, as did similar tissue from successfully colonized trees. 

Data on the fungitoxic effects of resin acids and oleoresin are just as conflicting. Wood with a high oleoresin content has an increased decay resistance (1, 13, 25, 46) and inhibits colonization by blue-stain fungi (32, 51). Gibbs (18, 19) has...
