Potential Damage
Lifecycle
Macroconidia are produced on small, cushion-like, salmon-colored sporodochia on dead shoots and twigs, particularly on needle fascicle scars. These are present year-round but most evident in autumn and winter. Conidia are colorless, 1-4 celled, curved and elongated, and are spread by wind, insects, and splashing water throughout the year.
