This page lists only South Dakota (and Midwest) mushrooms that have a stem and cap with pores or teeth. Some pores can be a few millimeters wide and some can be so small that the bottom of the cap looks smooth. If you want to identify other types of mushrooms such as spherical mushrooms, mushrooms with gills, shelf mushrooms, etc. please start on the main mycology page:

Albatrellus (unknown species)

Habitat: soil, deciduous woods, mycorrhizal
Spore Print: unknown
Season: found in late September 2022
Notes: I owe credit to my one-year-old for exclaiming “DADOO!” when I stepped over this tiny camouflaged mushroom. Fortunately his close proximity to the earth allowed him to see it so that I could study it! I was unable to obtain a spore print but I am guessing this belongs to the genus albatrellus due to these unique features: pores that run all the way down the stem and a clustered (attached) growth pattern.

Boletinellus Merulioides

Habitat: soil, deciduous woods (near rivers?), mycorrhizal
Spore Print: olive brown
Season: summer-fall (aug 1, oct 1)
Notes: this is the first bolete that I ever positively identified and ate. The pores have a weird “veiny” structure to them and the stem is always off center. These features make this bolete stand out from the others IMO. I thought it tasted good! Found mid August 22 in Sioux Falls then Oct 3 on the opposite side of the city.

Boletus (unknown)

Habitat: lawn, many trees nearby
Spore Print: ?
Season: found in late fall
Notes: I found this mushroom on a public lawn in Sioux Falls before I knew much about mycology. It has deciduous trees on one side and conifers on the other. No spore print was taken as I didn’t know how awesome this find was until I started reading mycology guides. I’ve been frequently visiting this area during the fall with the hopes of seeing it again but no luck so far! Guessing B. Auripes or B. Innixus based solely on old photos.

Polyporus Arcularius

Habitat: wood, saprobe
Spore Print: white
Season: spring
Notes: I’ve only found this in Spring but it supposedly sticks around all year. A similar mushroom, P. Mori, can be found on almost any hiking trail at any time of the year. The main difference is P. Arcularius has a definite stem which attaches centrally on the cap (P.Mori is a shelf mushroom).

Polyporus Badius

Habitat: forests, decaying wood, saprobe
Spore Print: white
Season: early summer through fall
Notes: When I first found this mushroom in 2021 there were over 25 large capped (8in, 20cm) red mushrooms covering a small area. I was blown away that I couldn’t find it in any of my mushroom books. Turns out, they were old and I was searching for the wrong color. The cap is very thin for such a large mushroom and turns dark reddish brown with age.

Polyporus Squamosis

Habitat: parasite on deciduous trees (elms!), saprobes of dead wood
Spore Print: white
Season: spring through fall
Notes: This mushroom is absolutely enormous and almost impossible to miss. If you find this mushroom when it’s young (cap breaks in chunks instead of flexing like leather) then it is totally edible. Technically a shelf mushroom, I have found it growing straight up from the ground on a short black stem so it is organized on this page to help new mushroom hunters.
