Your link does not work, Debbie. Here is a link to the first page of the paper “Observations on the genera Asproinocybe and Tricholosporum, and description of a new species of Tricholosporum (Agaricales, Tricholomataceae). Mycotaxon 38: 485-495.”

To see the other pages change the URL to the correct page number.

The other Tricholosporum paper is in Mycologia 74 and starts on http://www.cybertruffle.org.uk/...

Unfortunately that link only takes me to the cyberliber homepage, you may be able to get a direct link (Using the firefox browser) if you right click the page and go to “this frame > show only this frame”. I would like to be able to read Guzman’s paper too. :)

here’s a direct link to the Guzman paper on ciberliber:

The gross morpho similarities between these two genera have been noted by others over the preceeding two decades.

The two genera are thought to be fairly closely related, but hard to believe that they are members of the Tricholomatacea with those odd spores! Both can show the vinaceious staining on the gills.

What are the color of spores in mass?

It is difficult to compare micrographs with SEM photos, but the spores linked to from the Asproinocybe page show rounded to elliptical heavily nodulose spores; spores in the genus Tricholosporum are starifome or knobbed cruciate spores. This appears to be a better spore match to what Alan shows us here.

Some species of Asproinocybe also have lactifers! These may not be present in Tricholosporum.

I will be curious to see the DNA work on these. What chimeric organisms they are!

Isn’t Tricholosporum porphyrophyllum a Japanese species? Do you have any evidence of it occurring in Mexico? Here is a picture I found online for comparison.

Edit: Here are some more pics, I can’t say that they look like pine needles in the pictures… Though I haven’t seen a description yet so I’m not sure what they are associated with.

Here is some micro images to compare with.

aha! A new (ish) genus!

That explains why it didn’t fit neatly into the old ones…;)

Puedo estudiar ese material al microscopio?

interesting find!

did you get a spore print on these?
