Phleogena faginea is a fungal art from the family of Phleogenaceae . It is the only representative of the genus Phleogena . The fruiting bodies of the species , which arecommon on all continents with the exception of Africa,have a short stalk on which a spherical head sits,representingthe hymenium . The fungus grows saprobion table on the bark of deciduous trees .

Macroscopic features
The fruiting body of Phleogena faginea consists of a short, sterile stem with a spherical head that represents the fruit layer. In total, they are three to six millimeters high, the head section is one to three millimeters in diameter. The peridia, i.e. the outer skin of the head, is thin and smooth to fine-grained. The head is initially light ocher, but then turns brown and then black. With age, the head disintegrates and releases the light brown spore powder. The stalk of the fruiting body is cylindrical and white to light ocher.
Microscopic features
Phleogena faginea has a monomitic hyphae structure , so the fungus only forms generative hyphae. The hyphae are hyaline , the septa are buckled . Four spores sit on each of the hyaline basidia ; unambiguous sterigms are not present. The spores are yellowish brown, thick-walled and spherical. They have a smooth surface and are inamyloid . Occasionally the species forms conidiophores with broadly elliptical conidia .
distribution
Phleogena faginea is known from New Zealand , Asia, North and South America and Europe, where it is considered rare.
ecology
Phleogena faginea grows saprobion table on deciduous trees, especially on beeches ( Fagus spp.), Hornbeams ( Carpinus spp.), Poplars ( Populus spp.) And oaks ( Quercus spp.) As well as on species of the genus Prunus . However, the fungus was also found on spruce trees ( Picea spp.). In Central Europe, the fruiting bodies emerge from the bark of the trees in late autumn and winter and then grow very socially.
