Just looking at murriliana obsies after a recent DNA confirmation here.

I wanted to applaud you for your empathy for the actual fungi themselves! We have had much the same situation here in CA during our awful drought of several years. (up until this year, where we now are in flood stage: feast or famine!)

I too often felt guilt in picking a lone fungal example that mustered up the bare minimum of resources to produce a fruit body against all odds. But empathy is a GOOD thing!

Of course with all of the recent DNA analysis, a complete specimen isn’t even necessary. But that volva is obvious in your photo, and perhaps adds to our knowledge of what the cap color of murriliana looks like in its youth. It appears fairly obvious that color gets washed out or bleached from the expanding cap with time, if you look at the many obsies here on MO.

Under the conditions…

I’ll pass this time.

I know you’re on the look out for interesting things.

Very best,

I encountered two immature specimens and since this is uncommon to the area and it’s been so dry I made a conscious decision not to harvest either. As I was brushing the sand from the cap of one, I realized it wasn’t firmly rooted and pulled it out to find that the stem had separated from the volva (I did some reconstruction for the photos). So I have a specimen that is lacking a base, and probably isn’t developed enough to produce mature spores. You’re welcome to it if you like.

Interesting, Eric.

I see you didn’t get a herbarium specimen?

Very best,

Always in this same location.

Nice one, Bob!

I had not heard of this drab colored caesar. Have you found it before?
