Oh, wonderful

Thank you Alan!

I would never have guessed it. I had expected that if I encountered D. baeomyces, it would look a lot like Baeomyces rufus, but hadn't counted on finding it sterile, though I see from Dobson that it often is.

I gave up when the key in Smith et al. demanded UV (it's on my list), but given my K- reaction, I think I must have taken a wrong turn anyway.

And yes - it is K+ yellow, but very weakly so. My first test was absorbed rapidly into the dry soil, so didn't appear to develop, but a more liberal dousing does give a colour change that is clear when drawn onto filter paper.

Thanks again.

Edit: I can happily accept schizidia for Baeomyces placophyllus, but not here. Smith et al describes a schizidium as a "scale-like segment". Bobbles aren't scale-like. I am sure they make this stuff up as they go along. As Oliver Gilbert said, the subject is "running away from us".
