Observation 22377: Panaeolina foenisecii (Pers.) Maire
When: 2009-06-19
No herbarium specimen

Notes: LBMs is pretty much new territory for me. Stalks abot 3" long, slightly tapered from top to bottom. Cap margins became about 1/8" sulcate about 12 hours after picking. My scope may not be strong enough to notice the roughening of the spores.

Very back and forth at this point… Arguing opinions won’t get us far, hehe.

Yeah, the photo does not show this well at all. In fact, with the some what shiny black paper, the spore deposits show up really well against it. That effect combined with the fact that trying to convey true colour on varius cameras and monitors is impossible, makes this print look truly brown, not jet black.

Next time be sure to get a good, clear photo of the gills.

Not that looks deep brown

Don’t know, I’d say that was deep brown. But it puts it into the “black” spored genera at least, but really black is it.

I wish I could tell from the spores if they were warted or not there. I can just tell that they are dark spored with germ pores, but not if they are warted or not.

collected on the black strip disappeared; an indication that the color should be called black. No purple or brown tones seen against the black background. Photo does not really show this as well as I had hoped.

That spore print does not look jet black to me, it looks dark brown.

But my monitor has deceived me before…

Panaeolus

foensecii has spore print purple brown. Just noticed this in the guides as I had gathered a few suspected Panaeolus from my yard. I had assumed that Panaeolus shrooms had black prints. I guess this is why foensecii used to be placed into Psathyrella. Anyway, this necessitates a new guess at my collection seen here. I think the “girdling” color pattern on the cap may have faded for the ones seen here (22377). P. cinctulus has smooth spores. Called P. subbalteatus in Audubon.

print black… disappears against the black background on my print board. Attached a photo.

The spores on Panaeolina are pretty rough, I wonder if this could be a Panaeolus. Check the spore print color – is it jet black or dark walnut purplish brown?
