This is a more-or-less up-to-date arrangement of North American macrofungi, as a scientific taxonomy.
As an arrangement of scientific names, it can also be called a "phylogenetic taxonomy" or a "phylotaxonomy".

It is intended to supplement the arrangement of common names, the "folk taxonomy", here.

Both pages are comprehensive with respect to the names in the list.
In other words, all names in the list can be found, in each arrangement, where they (may) belong.

Scientific names aim for stability, precision, and rigor. Their classification must match evolutionary history (all taxa must be monophyletic). The names themselves are strictly determined by a set of rules (International Code of Nomenclature for algae, fungi, and plants).

Scientific taxonomy is impressively well-resolved and mostly objective. Most placements on this page are relatively impersonal choices, following consensus, authoritative, or recent taxonomy. For some debated or debatable taxa, the placements are less impersonal—I have made a few outright subjective choices hoping to keep names relatively easy, convenient, or aligned with field-identification features.

That said, this page is intended to represent a reasonable version of mainstream taxonomy, not a major revision of it. Efforts for intuitively convenient taxonomy are mostly concentrated on the folk taxonomy page.

for names above genus level, termination indicates rank:

-mycota	phylum
-mycotina	subphylum
-mycetes	class
-mycetidae	subclass
-ales	order
-ineae	suborder
-aceae	family
-oideae	subfamily

text weight indicates mushrooms:

• includes mushrooms
• does not include mushrooms

each name has a species list, accessible by hovering:

• for names with contents, hover over the open right-hand triangle: ▶ Ustilaginomycotina
  ▷

• for names without contents, hover over the name:
  Exobasidium
