Observation 167098: Hypomyces chrysospermus Tul. & C. Tul.
When: 2014-06-10

Notes: A strange looking fungus that I removed from the soil it was in at this park. Believe it was in an area of the park that is mowed frequently. Had to slice it open to try to figure out what it was. Maybe a Hypomyces on a gilled mushroom??

Walt, Daniel and Christian. Every time I post something I learn something new. I know I will have to start finding some Boletes so I can slice them and observe what they look like.

They aren’t “forms”

in the sense of being separate. Rather, the yellow and white colors represent different stages in the life cycle of the parasite. So a white one will eventually turn yellow (at least in H. chrysospermus).

And it’s worth noting that there are other Hypomyces to consider. H. microspermus is very similar and common in CA, others are undescribed.

I confirm Walt’s ID.

You can see it yourself in the 3rd and 4th photos. Those are pores. Hypomyces is an excellent guess, weed lady!
