Species complex?

Hi Danny, the discussion started on Facebook Cogumelos do Brasil. I don’t know if you followed. I learned that some people think that Lc. brunneoluteus and Lc. birnbaumii are the same species. Further it seems unclear if Lc. fragillisimus and Lc. thoenii might be the same species or related, if I got that correctly. But I would be hesitant to assume that African species occur in Brazil.
I have seen many different yellow Lc. with a brown center during my last stay at Cristalino. I was convinced earlier that they are all Lc.brunneoluteus , but now I rather think that they might be several species. I will send you a link to Dropbox with a selection of pictures. Further research is needed – that is obvious. Thanks for input, as always. S.

The description of L. thoenii is pretty brief. It’s basically an all yellow L. fragilissimus with different sized spores from Zaire. Most important to our purposes here is the lack of any mention of a brown disc in both the Florianopolis paper and the original description of L. thoenii. Maybe there is a more comprehensive description of the species elsewhere. Else, as always, will be the most appropriate person to ask.

I am curious to know what modern biogeography has to say about the relatedness between fungi from the Congo and fungi from Amazonian Brazil, but my default instinct is to be cautious in naming species on one continent by the names of species from another. I wonder if the Florianopolis paper is citing similarities between L. thoenii and L. fragilissimus just for fun or because there are valid records of both in Brazil.
