Unknown pyrenomycete
Joop van der Lee, 09-12-2015 17:06

Found on cow dung.
Fruitbody is covered with rigid, thickwalled, setpated hairs, 8,2 um thick, wall 2.5 um


Spores: 5.5-5.8x2.6-2.8 um, filled with 3 oildrops.

No asci found.

anamorph

Hi Joop,


without asci I would think of an anamorph :-)


I am not very good (better say bad) in anamorphs, but this reminds me a little of Volutella. Surely there will be a more competent answer later.


Regards from Lothar

Re : Unknown pyrenomycete
I do have photos of Volutella ciliata but fruitbody looks different and spore size is smaller and only contains 1 oildrop (4.8-5.5x2.65-2.75 um).
The underside does not colour orange as the previous one.
Hairs septated, thickwalled 9.1-9.35 um wide, wall 1.3-2.0 um.
I it possible that the previous one is an anamorph also.

Re : Unknown anamorph

I never said it would be V. ciliata (I know it isn`t), and I do not at all insist in Volutella. I only told you that it reminds me of species of this (form)-genus. This is still the case :-)

"I it possible that the previous one is an anamorph also" -


I would say it is more than possible :-)

Re : Unknown pyrenomycete
I only wanted to show you the difference but you made your point Lothar thanks.

Re : Unknown pyrenomycete
Hi Joop,
Lothar is right, your fungus  belongs the genus Volutella, all characteristics that you give fit well with this genus.
Regards,
Christian

Re : Unknown pyrenomycete
Hi Joop
Following Lothar and Christian's comments, the conidial size fits well for Volutella ciliata:
"(conidia 4.5-6.5 x 2-3 µm)" from Seifert, Kendrick and Murase "A Key to Hyphomycetes on Dung" (1983). I see it quite often on dung cultures . . .

regards
Chris

Re : Unknown pyrenomycete
Good evening and thank you to you all, I've already found several times this Hyphomycete, but not quite sure of the determination.

Michel.

Re : Unknown pyrenomycete

I found an article about Volutellonectria with Volutella anamorphs. I agree with Chris that this should be V. ciliata looking at the photos in the article. But what I thought to be V. ciliata can be V. asiana in my opinion. All Volutella anamorphs for Volutellonectria do have salmon-coloured sporodochia like with my first finding.

And by the way Chris can you send me the article of Seifert, Kendrick and Murase?

Re : Unknown pyrenomycete
Hi Chris

If you have Seifert, Kendrick and Murase "A Key to Hyphomycetes on Dung" (1983) as a pdf, I would appreciate a copy too.

Regards, Chris

I would be interested in both articles, too :-)
