Hypocreopsis rhododendri is an ascomycete fungus. It is commonly known as hazel gloves due to the resemblance of its orange-brown, radiating lobes to rubber gloves, and because it is found on hazel (Corylus avellana) stems.[1]


Hypocreopsis rhododendri is found on the hyperoceanic west coasts of Britain and Ireland, in the Atlantic Pyrenees in south western France, and in the Appalachian mountains in the eastern United States.[2]


In the Appalachian mountains, H. rhododendri was originally found growing on Rhododendron maximum,[2] and was subsequently found on Kalmia latifolia and Quercus sp.

In Europe, H. rhododendri is found in Atlantic hazel woodland, mainly on hazel stems.[1] It has never been found on Rhododendron species.


Although H. rhododendri is found on woody stems, it has been suggested that it is not a wood-decay fungus, but is instead a parasite of the wood-decay fungus Hymenochaete corrugata.[3][4][5]
