I found a photo of a specimen that I attributed to “penetratrix” in the field.

The stem was 210 mm long (about). I’m going to see what information I can extract from two photos of a single specimen.

Very best,

Rod

Let’s not worry about the poor battered and shriveled critter this time. You’ll probably find another one sooner or later. The spores wouldn’t be normal on an old specimen that’s been sitting around; and the likelihood that I could rehydrated (for example) the gills tissues is not very high.

For sect. Vaginatae the trick is “quick to the dryer and quickly dried.”

Glad to hear that you found electricity.

Very best,

There is remnats of a volva

If you look at the base there is a small amount of free tissue suggesting that is the remnants of a volva. The striations on the cap are very light to maybe my imagination. The cap has small scales on them that are easily knocked off. . I’m looking at the stipe and it has granular tissues very fine on the stipe. YOu can kind of see that in the pics There is a pic of the spores, was Thinking it would help with ID a bit? no? I added all the pics I have of this one, Maybe some thing will come out. I am 90% sure That the shriveled puny specimen is still siting in the foam coffee cup I used to make a spore print. It is very dry and very shriveled up and the base as of now is missing. I,ll send it next week cause the work week this week non stop.
IN Regards to Eva Nice to see you as well . I see you have really gotten into it. Nice Stats, Nice web site.Now that I have this thing called Electricity I’ll be able to post more.

I should add that…

I’m very sorry about the lack of data on “A. penetratrix.”

Several folks at a COMA foray collected multiple fruiting bodies of this type with a variety of cap colors all in the same year. I was exhausted because of internal bleeding earlier that same summer; and, to make matters worse, someone turned off the power switch controlling the dryers overnight. The next morning we had lost almost everything.

OK. Let’s say, the striations are a taxonomically useful character (for the sake of …

argument).

Then, the next question is about the pronounced umbo. Did you try to cut through the umbo? The species of sect. Vaginatae with deeply inserted stems that I know have an extremely hard and dense, pronounced umbo…like the perferatorium in the large species of Termitomyces. The perferatorium allows the Termitomyces to blast through a concrete-like termite mound and expand its cap above ground.

All that there is on WAO with regard to the North American Vaginatae with a pronounced, very hard umbo and deeply inserted stem is a placeholder page:

In the first photo (the one where the mushroom’s stipe is still mostly buried) I see marginal striations on the cap. However, they are short and faint. So I think it’s possibly that this feature may be a weather-induced anomaly (humidity?). The same photo also appears to show volval material along the cap margin.

Well, Eddee, if you’d like to dry it out completely,….

I’ll take a look at it.

The margin of the cap was non-striate…is that correct? I really can’t see striations in the photographs….but I thought maybe it was glare that was preventing my seeing them.

I know of several possible taxa (only from Connecticut) in sect. Vaginatae that have stipes very deeply penetrating the soil; however these have substantial (although somewhat fragile) volval sacks.

Very best,

Rod

Very small volval
By: Eddee (eddeeee)

If you look at the base it has a very small fragile voval. This was attached to a root mass. This is an Amanita of some sort Im pretty sure of it. I still have it. Its a bit dried out.

It looks like there may be some membraneous volval material…

scattered about the stipe base. Maybe a volva got ripped apart when the mushroom was excavated. Cap appears to be non-striate. So I’m wondering if A. cylindrispora is a possibility? Ring not looking quite right and occurrence away from a coastal area seem to weigh against this possibility. Just wondering… A. cylindripsora is such an oddball species!

I don’t think this mushroom is something with which I am familiar.

From your description of the penetration into the soil, I wonder if it is an Amanita. I only know such deep penetrations in sections Vaginatae and Lepidella. I can’t tell if there is a volval sac on the stipe base of your material.

Long time no chat. Hope all is well in your world. Been out of touch but now I have a house again. Ok This guy was deep. If you look at the pic that is the base The base just stops at an abrupt end. The base was attached to root mass from the tree. I dug and dug and left nothing behind.

Amanita solaniolens is a pretty small mushroom so far as I know. Can you tell us something about the stem base in this mushroom?
