Assessment Status Notes

Taxonomic notes

This striking species produces large rossete-like basidiomata growing on the ground. Some records of Cotylidia pannosa (Sowerby) D.A. Reid are mistakenly attributed to P. multizonata, but the former differs in having smaller basidiomata and lacking gloeocystidia on the upper pileus surface (Sjökvist et al. 2012).


Why suggested for a Global Red List Assessment?

The stereoid species Podoscypha multizonata is a conspicuous and easily recognizable lignicolous species with assumed low number of unknown localities. It grows at the base or buried roots of old oaks (Quercus) and more rarely Beech (Fagus sylvatica) and other members of Fagaceae in semi-open and sometimes grazed decidious forests and parks (remnants of old forests) with long continuity. Probably due to its specific ecological requirements, it seems to be a very rare and localized species that has been stated to be in decline in some European countries and is red listed in some countries (Hungary, Slovakia, Spain). The main threats to the species is habitat decline in area and quality due to change in land-use, e.g. densification, forestry and exploitation of localities.

- Few individuals in each locality, small total population and continuing decline fits with C-criteria. In Europe c 120 localities are known (c 80% is in UK and France, and 250 estimated as absolut maximum in Europe, and probably also Globally),  No of mature individuals < 5 000 together with inferred continuing decline, largest subpopulation < 500 mature individuals (usually far less and only a few mycelium in each locality).

Preliminary Global (and European) red-list assessment: VU C2a(i).


Geographic range

Podoscypha multizonata is distributed in Europe and Asia (also reported from N. America but material has not been compared with European type and probably constituts a different species). In Europe its distributed in the lowlands of Western, Central and South Europe; mainly in temperate zone, but also present in the Mediterranean. The stronghold of P. multizonata in Europe appears to be in the United Kingdom and France, where the number of localities is higher than the rest of the World combined. It is very localized and rare in continental Europe. The records from some countries should be checked and might be referrable to the look-a-like Cotylidia pannosa.


Population and Trends

The populations are declining due to changes of managing of the sites. We estimate that this fungus has been recorded in 70 localities in Europe in the last 20 years but two thirds of the localities are in the United Kingdom. Dark figures are estimated to be rather low, as this fungus is very striking and the habitat availability is low at European level. Thus, the total amount of localities is estimated to be maximum 200 in Europe (250 Globally). The vast majority of populations appear to contain very few individuals. The total amount of individuals in Europe is estimated to be <2000 (and Globally < 5000).

Population Trend: Deteriorating


Habitat and Ecology

The species is associated with old Fagus, Quercus and rarely Castanea, Carpinus, Fraxinus and Aesculus trees. It occurs on the ground by large trees, as a saprotroph or weak root parasite, typically in open forest, sometimes grazed, also in parks. Associated with Quercus suber in the Mediterranean area (Spain).

Temperate Forest

Threats

Survival and age structures (demography) of old host trees and decreasing habitat qualities are the main threats to P. multizonata. Sometimes host trees are cut down for safety reasons in parks, but more importantly still, slight but steadily ongoing changes in management of semi-open decidious forests sites negatively affect populations of P. multizonata . Overgrowth and densification processes of lignose vegetation are negatively influencing the populations. As subpopulations are small, scattered and consists of very few individuals at each locality, habitat fragmentation and random events are additional threats.

Logging & wood harvestingHuman intrusions & disturbance

Conservation Actions

Correct management and protection of sites where P. multizonata is known is crucial for conserving the species. A continuous supply of old Fagaceae trees in mixed and varied decidious forest stands will be important to avoid local extinction of P. multizonata in sites where it is present today.

Site/area protectionSite/area management

Research needed

It should be established wether E. Asian and N. American populations belong to the European species.
