Thank you for your off-line note on the dense, rounded caps of this species.

I’ve been picking up “destroying angels” from multiple sites this year. I want to see if the number of taxa that can be detected by DNA sequencing is stabilizing. I’m also taking detailed notes when I have the chance in order to have the data to use in sorting these deadly dames morphologically.

Maybe you could help we with words that distinguish the form the cap has in sp-O01 as opposed to other “destroying angels.” It seems to me that it is much more strongly rounded (as opposed to bell-shaped or rounded-conic) when the fruiting body is starting to open up. Your recent photos (here) particularly suggest this difference in “youthful form.”

What do you think of that? One of the reasons that I was asking about dried material is that these photographs seem to support this idea of a distinctive “early shape.”

Very best,

No dried material this time. Did you get the recent collection I sent you?
