Scientific name: Daedaleopsis septentrionalis
Derivation of name: Daedaleopsis means "having
appearance of Daedalea"; septentrionale means
Synonymy: Lenzites septentrionalis P. Karst;
Gloeophyllum septentrionalis (P. Karst.) P. Karst.
Occurrence on wood substrate: Saprobic; solitary or
overlapping groups on dead birch (Betula spp.) wood;
Dimensions: Caps up to 7 cm wide, 4 cm long, and
3 cm thick at the base.
Upper surface: Variably brown, darker with age;
densely concentrically zoned; surface finely
margin sharp and wavy.
Pore surface: White to grayish, then brownish with age;
surface bruises pinkish-brown when fresh; pores develop
into a lamellate configuration, lamellae (gills) thin, wavy,
and dichotomously forked.
Comments: Compare to Daedaleopsis confragosa. From
above, these two species are virtually identical and often
confused. The fertile surface of both species bruises a
pinkish-brown when fresh.
The two species can be reliably
on substrate identity and the configuration
of the fertile
surface. Daedaleopsis septentrionalis grows
birch wood whereas Daedaleopsis confragosa
a great diversity of hardwoods, including birch.
The fertile surface of
Daedaleopsis septentrionalis is
consistently lamellate whereas
has a much more maze-like and/or poroid fertile surface.
