Assessment Status Notes

Taxonomic notes


Why suggested for a Global Red List Assessment?

An uncommon inhabitant of two-year old needles of pines in Europe and, perhaps, west Asia. Fewer than 20 published records. If spraying against Dothistroma needle blight were to go ahead, this fungus could face collateral damage.


Geographic range

Estonia, Finland, Greece [1988], Hungary [2000], Ireland, Sweden, Switzerland, Turkey, UK [2008].


Population and Trends

Records from January 1921. Most recent record 2008. Probably fewer than 20 published records ever. Some (e.g. Ukraine) doubtful. Considerable overlap of records between different on-line databases. Reports that it is frequently encountered in the UK may be erroneous (BROWN, pers.comm.).

Population Trend:


Habitat and Ecology

Lophodermella conjuncta is found on needles in the second and third years of their life, and has been associated with premature leaf fall. Associated plants: Pinus mugo, P. nigra, P. sylvestris, Pinus sp. Other associated organisms: Cyclaneusma minus, Hendersonia acicola, Phaeoseptoria sp.


Threats

Recent outbreaks of Dothistroma needle blight have focused attention on control of pine needle diseases, including the possibility of control by spraying fungicide. If this were to proceed, there is a danger that L. conjuncta might populations might be unintentionally but adversely affected.


Conservation Actions


Research needed

This is a very inconspicuous fungus. The true extent of its population is not known.
