Scion is the leading provider of forest-related knowledge in New Zealand
Formerly known as the Forest Research Institute, Scion has been a leader in research relating to forest health for over 50 years. The Rotorua-based Crown Research Institute continues to provide science that will protect all forests from damage caused by insect pests, pathogens and weeds. The information presented below arises from these research activities.

: Lophodermiurn pinastri and L. conigenum (Ascomycete)

Common name: None

Country of origin: Northern Hemisphere

Host(s): Pinus spp.

Symptoms: Canoe-shaped fruit-bodies on dead needles (Fig. 35, 36). These species are not pathogenic and do not cause needle cast. They are endophytes that live in live needle tissue and fruit when the needles are cast. Spectacular fruitings often occur when the host sheds all of its needles for some other reason, possibly abiotic, and this can be misinterpreted as being caused by Lophodermium pinastri and L. conigenum.

Disease development: Spores are wind dispersed. Infection requirements are not known.

NZ distribution: Throughout New Zealand.

Economic impact: None.

Control: Not considered necessary.
