Assessment Notes
Justification
Cantharellus romagnesianus is a European species of ectomycorrhizal fungus. It has predominantly been found in northern Iberia and southern France, but there are records from Austria, northern Italy, Switzerland and the United Kingdom. It is well known, though with few records (e.g. on GBIF 2024), but it is a small species and can be overlooked. It is expected to have a large population size, and tolerates degraded habitats. Therefore, it is not expected to approach the thresholds for consideration as threatened under any criterion; and
C. romagnesianus is assessed as Least Concern.
Geographic range
The centre of this species' range appears to be the northern Iberian peninsula and southern France (I. Olariaga Ibarguren pers. comm. 2022). There is a recent record (confirmed by DNA sampling) from southwest England (Penna 2018). GBIF (2024) contains records from the Alpine region too, in Switzerland and northern Italy, while it also occurs in Austria (I. Krisai-Greilhuber pers. comm. 2023).
Population and Trends
This is a well-known species, but its small size makes it overlooked and new sites are being discovered now and then (I. Olariaga Ibarguren pers. comm. 2022). Given its relative frequency of occurrence it is unlikely to have a small population size. Its tolerance of disturbed habitats means that it is unlikely to be in decline, and it is assessed here as stable.
Population Trend: Stable
Habitat and Ecology
In the Iberian Peninsula it is always found not far from the sea and at a low altitude, in oceanic areas with no or almost no frost in winter. It is common and abundant along the Cantabric sea, where it occurs both in well-preserved forests and plantations (
Eucalyptus spp. and
Pinus radiata). It is associated at least with
Fagus sylvatica,
Castanea sativa,
Quercus robur,
Eucalyptus spp. and
Pinus radiata). It thrives quite well in plantations and disturbed forests where it is found often on bare ground or along tracks in slopes (I. Olariaga Ibarguren pers. comm. 2022).
The records from more Alpine areas (northern Italy, Switzerland and Austria), appear contradictory to the known range in the Iberian Peninsula. This may show how ecologically plastic the species is, or such records may warrant further investigation to confirm they are the same species.
Threats
There are no obvious threats to this species as it can tolerate degraded habitats.
Conservation Actions
No urgent conservation actions are thought to be necessary at this time. However, further research into the taxonomy of the Alpine specimens may be warranted, along with further investigation into its wider ecology.
