Niesslia exosporioides? => Niesslia typhae

Hello,

Found by Willy Heimeriks on 27-04-2019, The Netherlands, on Typha latifolia.

Could this be Niesslia exosporioides?

Asci: 8-spored

Sporesize: 10.9-10.9-11.7 x 1.7-1.9-1.9 µm

I see there is also a Niesslia typhae (Fig. 14)




Greetings, Riet

Re : Niesslia exosporioides?
Hello Riet,

I notice your link to my forum posting for a sample of a Niesslia sp., which I found growing on Typha latifolia in the United Kingdom.

I posted my sample to Walter Gams so that he could study it and he concluded that it was almost certainly a species of Niesslia new to science. During email correspondence with Walter Gams, I did agree a provisional Niesslia typhae spec. nov. with him.

Unfortunately, he was never able to work on describing this sample, due to lack of a budget for work on this genus.

Regrettably, he is no longer alive.

Unless anyone else is able to create a species description for this taxon, it will remain undescribed.

With Best Wishes,
Peter Thompson.

Re : Niesslia exosporioides? => Niesslia spec.
Niesslia typhae does appear to have been validly published:


If Peter has not been informed of this - or been sent a copy of the relevant publication - Mycological Progress 18(1-2):5-76 that seems a bit direspectful.

Perhaps if he contacts the publishers they would be able to correct this oversight.

Re : Niesslia exosporioides? => Niesslia spec.
Indeed not very respectful .... 
Thank you for your information Chris!

So the Dutch find could be Niesslia typhae?

Re : Niesslia exosporioides? => Niesslia spec.
Hello Riet and Chris,

I had no idea that the late Walter Gams' outstanding work on Niesslia had been completed and published earlier this year.

If it is believed that I am entitled to receive a copy of the publication, I shall investigate. 

Riet - Once a copy of this document published by Springer becomes available, it will then be possible to compare your material with the information published. 

Chris - Thanks for looking into this. I notice that Niesslia typhae is a blue entry in Index Fungorum. I wonder if work is complete on its creation as a new taxon?

Thank You,
With Best Wishes,
Peter.

Dear Peter,

This paper was published posthumously. Walter Gams passed away almost two years before. I think, to inform you was simply forgotten by the co-authors who finished the publication. I will send you a copy of this paper.

Best regards

Martin

Dear Martin,

I have received your email and the attached document about the new Niesslia species.

Thank you very much for your help with this.

With Best Wishes,
Peter.
