Mellitiosporiella?

Hi!

I am wondering if this is Mellitiosporiella sp. in your key, Zotto (Key to the genera Phragmiticola, Propolidium, Propolis (= Propolomyces) and Mellitiosporiella, the broad-spored taxa of propoloid fungi (Marthamycetaceae, H.O. Baral, Jan. 2015). Spores are 12-14 x 4 microns, 3-septate.  Asci 8-spored. I see no IKI reaction. All micros in water, except the last (Lugol).

Re : Mellitiosporiella?
Yes, the genus seems correct. You must look at the asci for a thickened apical and lateral wall. Maybe this is overmature? The colour does not fit M. pulchella. Did you compare the brick-red species of Eugene Popov in my key?

Re : Mellitiosporiella?
Yes, I compared with Popovs brick red species. This is no doubt the same species which I posted two years ago:


That specimen was sent to Jason Karakehian in 2018. In June this summer he wrote: "I am busy sequencing more genes for my doctoral dissertation work here at the University of Illinois Urbana-Champaign". In January 2019 he told me he was to receive more material from Popov. I haven't followed up since this summer. I assume you know more than me about his work.

Anyway, I will have second look at the ascus walls.  Cheers!

Re : Mellitiosporiella?
I di not remember your previous case. But the colour is not so bright as in Eugene's.

Hi Edvin, Zotto and AscoFrance forum. Edvin, this looks like the material that you sent me in 2019. I also have what appears to be the same from Eugene Popov. I am working on these right now and I will have a preliminary phylogeny by the end of the year. It has been difficult to get sequence from both specimens. The material that I have from Eugene is senescent and in both specimens I think that the pigments are interfering with PCR, but I do have some sequence from both so far.

Ah this is great, Jason!

Looking forward to your phylogeny, and hopefully we can start a bit the project next year.
