Recognized by sight: This appears to be growing on a Lactarius, possibly L. deliciosus. While the parasitic fungus currently is white, this is merely a short stage the fungus goes through, and the sectioned mushroom clearly shows the bright orange of either the mushroom (Lobster) it will be come, or the mushroom (Lactarius) it once was.

Hypomyces.

A somewhat common one on the east coast that looks like this is Cladobotryum verticillatum which is the anamorphe of Hypomyces ochraceus. The teleomorph is distinctive but I’ve only seen it a couple of times.

Hypomyces can go through several color changes to reach maturity.

It is also found on a much wider variety of species than indicated in Arora. Nonetheless, there is a white stage to H. lactifluorum, rarely seen because it attacks the button mushroom usually before it gets above ground. Most of my H. lactifluorum is on Russula brevipes on coastal sites. But where Lactarius is common (it still is fairly common this year) it can well be on Lactarius as well as Rhizopogon (hypogeous boletaceae) and Helvella. My point is this: simply because the fungus is currently in a white stage does not mean it will stay that color, and could change color abruptly within the next 12 hours.

Yeah, H. lactifluorum would be orange

H. lactifluorum would be orange, and on R. brevipes. This is probably a different Hypomyces.

Color?

I have never seen one at this early a stage of infection. Do they
change color to orange later, or would it be a differen species?

I agree it deffinately has been infected.

Hypomyces?

It reminds of a Russula with an early stage of a Hypomyces infection.
