Damage, symptoms and biology

Significant levels of defoliation occur in years following periods of moist summer weather favourable for infection. Increment loss and mortality may occur after repeated epidemics, particularly in young trees.

Other information

Other fungi, including Hemiphacidium longisporum Ziller and Funk and Hendersonia pinicola Wehm., often invade needles infected with L. concolor, competing with, or parasitizing the Lophodermium (Fig. e). A related species of Lophodermella, L. montivaga Petre., can be distinguished from L. concolor by its elongate, brown fruiting structures, and it tends to have a more northern distribution.
