Assessment Status Notes

Taxonomic notes


Why suggested for a Global Red List Assessment?

A resupinate/reflexed polypore first recorded in 2004, described in 2008 and with a worldwide distribution still apparently restricted to those parts of England exposed to the strongest Atlantic climatic influence (in the extreme SW and areas along or close to the S coast) and the Channel Isles (Guernsey).


Geographic range

Apparently restricted to those parts of England exposed to the strongest Atlantic climatic influence (in the extreme SW and areas along or close to the S coast) and the Channel Isles (Guernsey).


Population and Trends

From observations of inhabited deadwood and the mycelial territories delimited therein, this species seems to be present as a single mature individual per fruiting patch. Such patches are relatively short (usually <15cm) and so fruiting patches can be taken as representing mature individuals. Around 200 mature individuals are known from England and Guernsey.

Population Trend: Stable


Habitat and Ecology

White-rot saprotroph of small diam dead branches (usually attached)  of various shrubs and stems of some woody herbs, perhaps most frequently found in Atlantic coastal thickets of Prunus spinosa although also recorded on Carpinus, Chamerion, Corylus, Malus, Rosa, Rubus, Salix, Ulex.
