I’m pretty sure the green stuff was algae growing on the charcoal, not moss.
I distinctly remember finding this in a recently burned area that was fairly far from the SFSU Field Station. I know at least Chris Shanks was with me at the time. I’m pretty sure we would have brought it back and scoped it. It’s possible it was ultimately determined to be P. omphalodes.
no Pyronema domesticum was noted for 1995, the earliest data shown in the 2011
Spring Fungi of the Sierra Handbook. It was not collected after that date, either.
Pyronema omphalodes was found in 1995, but that doesn’t mean that this was the one that they found; again, these are cups, not cushions, and not on burned ground or in greenhouses or in heat dried soil, but on green moss.
A Pulvinula sp. was recorded in 2003.
but any course participant could check the checklist in the reader and see if the original proposal is among the taxa reported. that would probably mean it had been scoped and confirmed by instructors.
these are cups, not cushions.
Can’t see the hairy edge of P. domesticum (altho slide to digital always loses detail).
Domesticum occurs in recently sterilized human landscapes; this looks like a moss bed in the woods.
Why not Pulvinula, instead?
BTW, I am getting these deeper details from the new Beug NA Asco book, something that Dennis’ class wouldn’t have had the benefit of back in 1995.
I found this obsie by randomly searching all of MO for its most popular obsies; this one was on page 6. Funny what pops up.

it is not easy to remember the details 20 years later!
since P. omphalodes was actually listed for that year, makes sense to call it that here.
