Observation 57994: Entoloma subgenus Pouzarella (Mazzer) Noordel.
When: 2010-10-20
Herbarium specimen reported

Notes: 10-20-10
Rowan Co., NC
USA

Found in groups, growing from moss covered sandy soil (not very sandy but sandier than your average forest soil) on the upper part of an old creek bed that is around 4-5ft deep, in mixed, predominantly hardwood, forest.

Pileus:
2.2 cm broad, conic or pointed, densely hairy or fibrous, brown, margin straight (not curving inward or up) and hairy.

Lamellae:
Adnexed, between close and distant, more-so distant, creamy to creamy brown

Stipe:
4.1cm long, .2cm wide, creamy fading downward to darker brown, minute hairs covering stipe’s entirety, equal but ever so slightly enlarging at base, appears solid but could be ever so slightly hollow.

Smell:
Faintly mushroomy

Spore Print:
Sandy brown, or peachy-brown?

Angular (4-6 sided), some subglobose to elliptic?

Camera

Thank you for being so helpful and nice Irene!

I’m using an ordinary camera for the micro-shots.
The model is a Sony DSC-W7.
I just hold it up against the eyepiece and turn the flash off.

Once I get my ocular micrometer, I’ll post the spore measurements.
Thanks again!

Exactly!

Well done, this is the kind of brown hairs you should expect on Pouzarella nodospora!
It’s a promising ID – even if it might be some other closely related species.
This is a better documented obs than most of the others here at MO :-)
But do keep the collection for further investigations.

Congratulations to the microscope! You’ve got pretty clear and sharp micro photos too. Are you using your ordinary camera for the shots, or a digital eyepiece camera?

Stipe Hairs

I just posted pictures of (what I believe to be) the stipe hairs.

I couldn’t really see any hairs by viewing the stipe with the naked eye.
(I guess they shrunk up a good bit upon drying.)
So I scraped the stipe’s surface with a razor blade over the slide and put a drop of water on it.

I’m guessing this is what you were talking about when you said “brown hairs on the stem”, Irene…

I think so

but you could always ask them about that at Amscope, they should know. If the difference is just a couple of percent, it’s negligible.

Ocular

Thank you for the knowledge Irene.

So just to make sure: If I buy the ocular (I think it’s a 10x eyepiece at Amscope.com), then I should be good to go without getting the stage micrometer?

Measuring

What you need is an eyepiece (ocular) with a scale, or an ocular micrometer to add above the lens. It should be available to your microscope.

Older microscopes also needed calibration with a micrometer slide. I don’t know if it’s necessary. The scale usually follows the stated magnification good enough in new microscopes, at least when it’s pre-installed in the eyepiece.

Ooo Fancy!

Touch screen huh? Cool stuff.
I got the Amscope model B370B.
Good to see you around as well.

I did!

get one too! It’s super neat, touch screen! but i have the same trouble as you, no measurement function to show. Have fun! good to see you around!

Measuring Spores

To Irene:
Thank you for the compliment on my photos.
I’m unable to measure the spores at the moment and I’m not really sure what parts for the microscope I need to buy to be able to measure spores.
I’ve read about stage micrometers and ocular micrometers but am confused about which to get, or do I need both for calibration purposes?
Could you suggest what I need for measurement?

Also I’ll try to check out the hairs under the scope soon. Thank you for suggesting this.

To:
Britney
I’m glad that I got one too! haha. I’m assuming you did? (congrats)?
But yes it is definitely entertaining. I can’t wait to get some KOH, I just cant really find any in smaller amounts. I found a bottle of Flakes that was 2 pounds, but I don’t need that much.

Awesome

So glad you did get a microscope! No Melzer’s here either, but fun all the same.

Nice micro shot
By: Irene Andersson (irenea)

of Entoloma spores! I’m not familiar with the Pouzarella you have suggested, but it should be possible to ID by its brown hairs on the stem. You could try to get a picture of those in the microscope. Are you able to measure the size of the spores too?

By: Matt Sherman (Shermanii)

I just got a microscope so forgive me if I’m terrible at using it.

I put the spores on a slide and added a drop of water. (I don’t have melzer’s)

But check out the spores if you want to.

Any advice is welcome.
Thanks.
