Assessment Notes

Justification

There is very little information available for this species, and a high degree of uncertainty surrounding it; especially regarding its correct taxonomic placement. At this time it is not possible to accurately assign a Red List category to this species, and so it is assessed as Data Deficient.

Taxonomic notes

This name is not applied consistently (I. Olariaga Ibarguren pers. comm. 2022), and based on its ecological characteristics it is presumably not a true Cantharellus. Indeed, Wallroth (1833) suggests its habit resembles Peltigera aphthosa - a lichen!

---

Geographic range

This species was originally collected from Thuringia, Germany (Wallroth 1833). There is no further information.

---

Population and Trends

There are no data regarding the population size and trend.

Population Trend: Unknown

---

Habitat and Ecology

This species was collected from the mossy trunk of a Populus tremula (Wallroth 1833). No further direct information is provided, but this raises doubts as to whether it is a true Cantharellus as species of this genus are mycorrhizal. Concerns over its taxonomic placement are furthered as Wallroth (1833) compares its habit to that of Peltigera aphthosa - a lichen.

---

Threats

Further information is required regarding the full distribution of the species before an accurate assessment of the threats it faces can be made.

---

Conservation Actions

A further assessment of the taxonomy of the species is needed in order to ascertain whether it is a valid species or not. If it is, then research is required in order to ascertain key parameters such as the full distribution, population size and trend, as well as to investigate its life history and ecology.
