Hemiphacidiaceae on Typha?
Joey JTan, 23-03-2016 16:04

I regrettably did a poor job characterizing this specimen last year, but I wonder if someone recognizes it?  I believe it is in the Hemiphacidiaceae but I am unaware of a species like this on grass.

Collected in the spring from dead grass leaves (possibly Typha latifolia) in a damp environment.

The ascomata are ca. 350 um diam, erumpent, leaving a small flap of host tissue as they emerge.  The asci are eumayloid, parpahyses lanceolate and exceeding the length of asci, ascospores 6-7 x 2-2.5 um.

I wish I had more images (especially vital in water), however this is basically all I have.  I did manage to culture it at least.

A few more images.  I think I was quite taken with the asci and paraphyses in IKI/KOH that day...

Hi Joey

there is actually a Hysterostegiella typhae, and I believe it is this species.

Please let me know if you find anything interesting with your culture.

We have merged this family in the Cenangiaceae (see my poster on invivoveritas). For Hysterostegiella I cannot remember a single existing sequence!

Re : Hemiphacidiaceae on Typha?
Of course!  I was reading Hein's papers just last week and I didn't make this connection... I was just thinking about Mollisia at the time.

The cultures looks as if they are trying to produce ascomata, but nothing so far.  I will try to sequence it in the near future and let you know the results.  

Thank you very much, it is great to get a name on this one.   Â
