''Daedaleopsis'' is a
genus of
fungi in the family
Polyporaceae. The name ''Daedaleopsis'' is a reference to
Daedalus, the labyrinth-maker of myth. Similarly, the maze-like pattern of pores is taxonomically described as being daedaloid.
DNA was recovered and
sequenced from fragments of a nearly 7000-year-old fruit body of ''
D. tricolor'' found in an early
Neolithic village in Rome.
Taxonomy
The genus was
circumscribed
In geometry, the circumscribed circle or circumcircle of a polygon is a circle that passes through all the vertices of the polygon. The center of this circle is called the circumcenter and its radius is called the circumradius.

Description
''Daedaleopsis'' fungi have
basidiocarps that are
annual, with a
cap or effused-reflexed (crust-like with the edges forming cap-like structures). Their colour is pale brown to deep red,
zonate, with a mostly smooth cap surface,
lamellate to tubular
hymenophore, and a pale brown
context. Microscopic features include a trimitic
hypha
A hypha (; ) is a long, branching, filamentous structure of a fungus, oomycete, or actinobacterium. In most fungi, hyphae are the main mode of vegetative growth, and are collectively called a mycelium.
Structure
A hypha consists of one or ...

clamped generative hyphae, and the presence of dendrohyphidia. ''Daedaleopsis'' has

Habitat and distrituion
''Daedaleopsis'' fungi cause
white rot, and are widely distributed in the
Northern Hemisphere
The Northern Hemisphere is the half of Earth that is north of the Equator. For other planets in the Solar System, north is defined as being in the same celestial hemisphere relative to the invariable plane of the solar system as Earth's Nort ...
