Overview
This is a collection of sightings of fungi that are often associated with Eucalypts. There are three categories: Parasites, Mycorrhizas, and Saprotrophs.
Major parasites cause dieback. Mycorrhizas support growth and plant health. Saprotrophs are decomposers of heartwood and leaf litter, and they help form tree hollows for wildlife.
In the examples below, the taxa with a # have sightings in the collection.
Some fungi do not have conspicuous sporophores, so direct sightings are unlikely. If a Eucalypt is unhealthy and you suspect it is due to a fungi or fungi-like parasite then add a sighting to the related collection project, 'Eucalypt health surveillance' https://canberra.naturemapr.org/collections/sightings/10933
Parasites
Parasites include fungi-like parasites, root rot fungi, canker fungi, and leaf fungi.
Examples of parasites:
Pseudosydowia eucalypti has been the cause of dieback of Eucalyptus globulus planted overseas. In Canberra and the Southern Tablelands it affects E.globulus subsp. bicostata.
Some leaf fungi that are parasites, allow access for saprotrophs. In this way Eucalypt leave decay can commence before leaf fall.
Mycorrhizas
Mycorrhizas include VAM, and ectomycorrhizas. Examples of mycorrhizas with conspicuous sporophores: Lactifluus wirrabara, Tricholoma eucalypticum #, Cortinarius archeri #, and C. austrovenetus #.
Saprotrophs
Saprotrophs include white rots and brown rots that decompose heartwood and logs, and litter (i.e twigs, bark, and leaves) decomposers.
Examples of saprotrophs:
