poroid fungi in the family
Meruliaceae
The Meruliaceae are a family of fungi in the order Polyporales. According to a 2008 estimate, the family contains 47 genera and 420 species. , Index Fungorum accepts 645 species in the family.

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.

Rolf Singer (June 23, 1906 – January 18, 1994) was a Germany, German-born mycologist and one of the most important Taxonomy (biology), taxonomists of gilled mushrooms (agarics) in the 20th century.

type species.
This fungus was originally
described by French mycologist
Narcisse Théophile Patouillard] in 1915 as ''Daedalea philippinensis''.
Description
Basidiocarp, Fruit bodies of ''Diacanthodes'' fungi have circular
caps that may be partially funnel-shaped (infundibuliform), and a surface texture ranging from
tomentose (covered with densely entangled hairs) to strigose (with stiff, sharp-pointed hairs). The colour of the pore surface is light brown, but it darkens with time.
''Diacanthodes'' has a dimitic
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 ...
l system, meaning it contains both generative hyphae and skeletal hyphae. The generative hyphae have
clamp connections; the skeletal hyphae are thick-walled to solid, and have a weak
dextrinoid reaction. The
spores are broadly

suggests that ''
Bondarzewia'' may be the genus most closely related to ''Diacanthodes'', based on
morphological similarities. Both genera feature ornamented spores, the same hyphal system, and similar
habit. They differ in microscopic characteristics: ''Bondartzewia'' fungi have clampless generative hyphae, no
cystidia, and amyloid spores.
Habitat and distribution
''Diacanthodes'' has a
pantropical distribution. Its fruit bodies occur on the ground.
