I agree it can’t be much else. Thanks for you input, very much!

Sorry, my error

I have a book with swedish earthstars, and there’s a scheme with the number of rays. On a closer look I realize that the rows with species names are displaced in the scheme, and the numbers refer to quadrifidum (of course! What was I thinking..?)
Anyway, I have seen them with less than 5 rays. And I don’t know of any other possibilities, except that there are some different varieties of it described.

Arora says 5-12 rays, usually 6-10….

So that is why I was wondering. Do you have a source that says 3-5? These two specimens each had 4.

I still think G. pectinatum is likely, I was just curious if anyone knew of any other possibilities.

Agree with pectinatum

It’s also one of the species with the fewest rays, usually 3-5.

Anyone know of anything similar?

The two I plucked only had 4 large rays as opposed to 5 or 6 like G. pectinatum. Any ideas of other beaked Earthstars with a pedicel?

cool find!
