Oh no! Another one of those!

These things are hard enough without “faking” septae in their spores. That’s just perverse! :)

After all: is this Toninia sedifolia?

I just read the following remark in the JM Lucas webpage about the spores of T. sedifolia: “spores uniseptées mais apparence multi-septée (globules huileux)”. Can this be the explanation for what I observed?

I think that it happened again.

I have no definitive answer for the classification of this specimen, but it doesn’t seem to be T. sedifolia. What I could understood from the microscopy is that most problably we are in the presence of a Toninia with fusiform to acicular spores which are more than 1-septate (see another one with this feature in observation 107285), though the photos are not fully clarifying.

I see!

Interesting that those two species key out completely differently in my keys, yet looking at your photos, I can see a strong resemblance. This one does look like it has much more convex squamules and is more pruinose than even the most pruinose specimens you’ve posted of T. aromatica.

I don’t generally pay too much attention to your Toninia because I know so little about the group, but this one really jumped out as being exactly like stuff I’ve seen in North America.

Thanks for the comment.

Yes, but …

according to my experience here, even those which seem like T. sedifolia, always end up with 3-septate spores, thus pointing more to T. aromatica. Definitely it doesn’t look T. aromatica this time. I will try the microscopy and return here with new data if possible.

Looks just like T. sedifolia
