Aha!

So there is another, larger species – A.pteridis. It’s claimed to be up to 12-15 cm. – that’s huge. My specimen was less than 10 cm. But on the other hand, it was growing very close to a cluster of A.hygrometricus that were much smaller and looked different. I just looked in “Trial field key to the species of SCLERODERMATACEAE in the Pacific Northwest”, and size of the mushroom is one of the key features separating A.pteridis and A.hygrometricus, along with features that can’t be seen in these photos.

A.hygrometricus, again.

I just thought there might be other species similar to Astraeus hygrometricus – field guides have an obnoxious habit of posting only the most common species of the genus. Oh, well.

Fairly large

This earthstar was much bigger than average Astraeus hygrometricus found in the vicinity – roughly 3 inches for the former versus 2 inches for the latter.
