The white stem cup ( Hymenoscyphus albidus ) is a fall foliage-decomposing mushroom from the subdivision of the real cucumber . Hymenoscyphus albidus lives on the leaf spindles of shed ash leaves and is common in moist ash forests. Its fruiting bodies are white cup-shaped apothecia with a size of 2 to 7 mm. The species was first described as Peziza albida in 1851 .
From 2008 to 2010 the white stem cup was considered to be the main fruit form of the anamorphic Chalara fraxinea , which has become known as the causative agent of ash dieback .
The newly discovered main fruit form of C. fraxinea was first described in 2010 . Except for the size of the spores, this fungus is morphologically similar to the white stem cup and can only be distinguished from it by molecular genetic investigation methods. He received the name Hymenoscyphus fraxineus or false white stem cup .
