As far as this spotting, I’m sorry, I moved on yesterday so can’t dry and send you the material, but have written to the owner of the Lodge to see if he is interested to do it. I described where I found it. There was only one.
This is a quote from Wiki about the forest “The reserve houses a tropical dry forest ecosystem, within the reserve the flora consists of over 500 species of plants and tropical dry trees, such as pochote, black rosewood, mahogany, hogplum and guacuco, as well as a large variety and amount of orchids.”
Laguna de Apoyo (Lake Apoyo) is Nicaragua’s largest volcanic crater lake. I found it very close to the lake on a small path up into the forest. There were a lot of low lying bushes and grasses beside the path. It was amongst these.

I am working on getting the material to you.

If all else fails, I will have someone scope and sequence it from afar.

I don’t know, Danny.

Dr. Felipe Wartchow reports that Brazilian material that he has reviewed lacks clamps at the bases of basidia, falls into Dr. Bas’ stirps Thiersii, and is morphologically very close, if not the same as, the African A. aureofloccosa. The Mesoamerican material of aureosylvatica has clamps at the bases of basidia and would fall into Dr. Bas’ stirps Nauseosa.

Our Mesoamerican material has all been sampled for DNA sequencing. We don’t know yet if we are lucky enough to obtain an data.

The clamps might be an indicator if you found them (or searched hard and couldn’t find them) in the Bolivian material.

Very best,

What about Bolivia?

We are getting close to publishing this species.

If you can dry material and send it to us, we could make good use of it in preparing the original description. At present, we think that A. aureosylvatica has a range from Florida, USA to Barro Colorado Island, Panama.

Can you characterize the forest type in which you found the species?

Very best,

Rod Tulloss
