Observation 68552: Panaeolina foenisecii (Pers.) Maire
When: 2011-06-01
No herbarium specimen

Notes: These start fruiting in the grass around my apartment complex every spring around late April-May(bit later this season because of the cold weather).

Found every spring here in Western WA in fields, lawns, parks, and all other well watered grasses areas.

Much smaller than P. subbalteatus, P. campanulatus etc.

Spore print: Purple/brown

First spore print I took on 6/1 looked purple in my car lighting- took another on 6/2 and they appear to be black.

Here are spore prints taken today from the same patch as 6/1. I was totally wrong with the spore print I took yesterday- they are definitely BLACK spored.

Spore color

Appears black is not jet black. I can see the color in your pictures, they’re not jet black.

You can find spore print comparison shots in these two observation, http://mushroomobserver.org/65540?q=4h51 & http://mushroomobserver.org/67737?q=4h50

Douglas, I don’t believe there is a correct way to photo the spore prints as long as color balance issues can be avoided. I find on foil and in natural light makes this easiest. Others have succeeded with other methods. Also, I will add microscopy for a few observations today or tomorrow after I read up on using immersion oil (My 1000x pictures using h20 came out lacking…)

Weird, the link works for me….

Scope of spores…

Yes, the images of the spores in the scope will help. Actually that would be the only thing that would really id the mushroom. That is what we need, a few more obs. where there is a photo of the spore print, with the mushroom, and the spores at 1000x in a scope.

If there is concern about the method to photo the spore print itself, what should be the correct way to determine the spore print color? Take the print on white paper/black paper/foil? Natural/Sun light? If we get a set of spore prints, it would be good to not have them also questioned…

Link just has a shroomery logo :(

Tim, your link for Panaeolus spores is just coming up as a logo for the shroomery for some reason…

I originally posted this as P. foenecesii yesterday and had no qualms about the validity of the post- just threw away my spore print page that was in the car… In response to Douglas Smith I took another spore print today and they seem really dark- more black than purple. I have two digital images I just took with my scope if that helps with further I’d.

Looked purple to me too yesterday-

They appear black up close in my kitchen light today though… Everything else checks off for P. foe’s other than that.

Here is a useful image for Panaeolus spores…..

I’ll add a pic of spore print tomorrow.

Now purple…

Ok, now the spore color is purple…

If you have taken a spore print, can you document there here? Take a photo of the print and include it in the obs. here.
