Amanitas show up 1 to 4 days after a heavy rain.

We just had another test of this observation at the NEMF 2017 foray. The day after the heavy rains stopped we got two uncommon amanitas among several that had not been found previously. I have the impression that a great burst of taxa was about to start up the day we had to go home. :)

We are at their mercy. :)

Very best,

Rod

I didn’t find another.

Unfortunately two weeks later I could not find another specimen of this. Neither at the exact spot or a wide area around it including traveling far towards and away from it. I suspect that either I showed up near the end of this species appearance time when I first found it or that it is barely found in this area and only able to make one mushroom. Next year I will return here a month earlier in case then this year in case it is a better time for it and if I don’t find it then I’ll return a month later at the same time next year.

Great!

My area (including where I found this) got heavy rain again the past week so my next trip (which will be just over two weeks from when I found this) will be to the same area. Most mushrooms of any species seem to appear over the space of three months with one month being prevalent. I can only hope this was found “early” in that time period so I’m more likely to find it. Otherwise I’ll have to return at the same time next year.

Whoa!

I have a dehydrator and would GLADLY have taken the few minutes it would have taken to prepare the sample then ship it to you! Unfortunately…I didn’t save it other than needing to break it apart for identification (like to make a spore print). If I ever find this again I WILL do that. In fact this area was large enough to visit twice to explore fully and this was the first time I’d ever been there. Now I just have to hope it rains heavily in that area again in the next two months so I can look again.

Hello, Chris. I’m with David.

None of the white destroying angels have marginal striations on the cap. And none lack a partial veil unless a slug eats it or something else untoward happens to it. Also, all the Phalloideae have a bulb inside a membranous volva while the Vaginatae never have a bulb from the get go.

If you see white Vaginatae again and have a dryer and the time, I’d really like to examine dried material of the mushroom you have depicted in this observation.

Very best,

Rod Tulloss

Chris, a ring can drop away.

With some types of Amanita this is more likely than others. But I don’t think the one seen here is a species from section Phalloideae http://www.amanitaceae.org/?section+Phalloideae . I like Igor’s proposal for section Vaginatae. The marginal striation along the cap support this proposal. Another possibility, but not likely given the cuplike/membranous volva, is Amanita albocreata.

Looks like your area is receiving a lot of rainfall. Should be a great week of mushroom hunting on the horizon for you.

WAIT!

There’s no ring on this. How did I not notice that until after I posted it?
