Inmersed on Carex
Enrique Rubio, 24-04-2014 19:52

Hello forum


I found these minute inmersed fr.bodys on leaves of Carex sp. on a very wet place. The pale lips of the fuitbodys are never fragmented and the hymenium is very pale too. The fusiform asci seem to have a little apical apparatus IKi dirty red, and the ascospores a 3-septate only visible in IKI


I think this fungus could belong to the Naeviaoideae, but I'm not sure


What's your opinion


Thanks again

Re : Inmersed on Carex
Hi Enrique

is the inner margin composed of periphysoids? (horizontal hyphae forming a palisade)?

I have no idea. With my database I have only
Phragmonaevia hysterioides Ellis & Ellis p. 529
but that has very elongate apothecia.

Hi Zotto


Unfortunately I don't know how the margin is because I cannot cut it by the very snall size of the apothecia. By the way, today I heve seen the flower of this plant and I know it is not Carex but Iris pseudacorus!

Re : Inmersed on Carex
Dear Enrique,
This looks very like Karstenia inconspicua, a taxon I described on Deschampsia caespitosa leaves from north Argyll in Scotland.
The species was published in Mycologist Vol.13 Paret 4 in 1999.
The structure was very basic: just a few layers on textura angularis. Spores 3-septate at maturity, 10-12 x 2-3. The fungus was very difficult to see as it as concolorous with the dead leaves.
Hope this helps,
Peter Wilberforce

Re : Inmersed on Carex
Hi Peter & Enrique

The description of K. inonspicua is indeed similar,  except for the much smaller spore size. The total absence of periphysoids in that species make me wonder where it belongs. Karstenia is impossible because there the paraphysoids are very developed. Cryptodiscus could be another choice, but also there periphysoids are present though only above the hymenium. In both genera the entire hymenium always reacts heimamyloid (strikingly blue in iodine after KOH-treatment). Enrique's specimen seems inamyloid except for the apex.

So I think the fungus is helotialean rather than ostropalean.

Re : Inmersed on Carex
Hi Enrique,

did you consider Laetinaevia longispora? It obviously occours on a variety of alpine herbacious stems. I personally have no idea of the macroscopy of this species.
Here is the description by Hein 1976.

Best regards
Martin

Re : Inmersed on Carex
Hi Enrique, If you would like sections made of this material and you have some spare, then I would be happy to do them for you. I have a base-sledge microtome and freezing stage, so it would be no problem. Just let me have some lightly dried material and I'll do it for you.

Re : Inmersed on Carex
Laetinaevia I know only for species without a raised margin, very different from this. Diplonaevia would more fit by macroscopy.

Re : Inmersed on Carex
Hi Zotto,

as I said: I have no idea of the appearance of. L. longispora. It was just a proposal...
Are there Diplonaevias with septate spores?

Martin

Re : Inmersed on Carex
Hi Martin

Diplonaevia species are mainly non-septate or sometimes 1-septate (Hein 1983), see alo in Cubby. But Enrique's fungus might anyhow belong in that genus.

Many thanks to all.
