It’s not easy. Between those three, I would be in doubt between Cyclophorum and Striatum.

Elsa — I’m inclined towards cyclophorum as well — but, look at images of striatum or even pulchellum. All three taxa can very in color, so that’s little help. They can be easily separated microscopically unless they turn out to be something else entirely. Tulostomas are defiant and make lousy pets.

My bet was right, then :)

Just put up an observation (136740) of an identified cyclophorum for comparison.

Not lesliei, cyclophorum a good candidate.

Wright’s monograph describes many species found in South Africa. Lesliei has a tubular mouth, so it can be eliminated. With a good 20X lens, a steady hand and nice specimens like these, you should be able to see the mycosclerids in the endoperidium, that would clinch it for cyclophorum.

Good call, Elsa

When the book was written, only two species were known, T. lesliei and T. cyclophorum. I haven’t found any picture of lesliei, but this obs looks a lot like other pictures on the web of cyclophorum..!

I never saw any, so

I’ll be quiet. I found this book, maybe it is helpful.


Tulostoma for sure, but which one?

If I had found these in the western US, my hip shots would be: pulchellum, striatum, or cyclophorum. I’d like to say “drop some spores in an envelope and I’ll see if I can identify the species”, but somehow I don’t see that ending well. These are a nice collection. If you still have access to them the National Mycological Herbarium in Pretoria might like to have these. Tulostomas are not often collected, BUT SHOULD BE.

Notice the exoperidium, like an opened flower at the base?

Plus the rounded area around the apical pore, make Tulostoma pretty likely.

Thanks, irenea

It does

look like they have a stipe. Usually most of it is buried, and these have the right kind of exoperidium. Tulostoma seems like a very good idea.

By: Danny Newman (myxomop)

with no stipe?
