she said that the purple context of cap and stipe is the real clue to this creature’s identity. Since Sarcodons are one of the great dye mushrooms, she has scads of experience with this group. it did indeed have a solidly purple context, so fuscoindicus is the best fit at this time.

Arora emphasizes the tooth color in MDM, which is the source that I used originally to make this ID. Always good to have multiple sources.

Well sure,

with spore drop. But these were brown on the inside. Do you also have photos of the tooth context of other truly purple toothed Sarcodons?

The descriptions in Arora are probably not detailed enough to make determinations as to species, which was my only source. Cap texture certainly changes with age and drying in many mushrooms. It was Irene who debated that point.

Is there a better, original species description somewhere that speaks of the entire spine changing from purple to brown, inside and out? In other words, a color change that is not superficially applied to the surface?

The fruit body that David collected three days before I took its photo also showed zero purplish coloring of the spines at the time…and was neither old nor dried out. The vast majority of actual fuscoindicus photos here on MO do show at least a hint of purplish color somewhere on the teeth, and none of those had sectioned teeth to “prove” your point.

is typical old dry Sarcodon fuscoindicus. The spines go BROWN in age, the cap gets scales when it becomes dry…

Not sure how much the spine colour matters, but I’d stick to Sarcodon sp..

S. fuscoindicus is described with a smooth cap, and fuligineoviolaceus is not convincingly proven to occur in North America.

teeth had brown not purple context.

see photo.

I will section a spine…

and see if your theory is correct, Irene.

Could still be fuscoindicus

when the spines are covered with brown spores.

NOT fuscoindicus…

with those BROWN spines.

I agree that it might be something else, though…but what?

By: Irene Andersson (irenea)

I agree that this probably isn’t fuligineoviolaceus.
Neither is your obs 77805, but what is that?
