Iodophanus or Thecotheus 310116
Miguel Ángel Ribes, 07-08-2016 20:41
Miguel Ãngel RibesGood night again

This small (500-600 µm) white apos were growing in a Sus scrofa dung, at 1.340m, inside an Abies forest. First we think about a Iodophanus, but I think it don't fit Ok with none. So, we thought about Thecotheus, but I don't find any similar.

Could you help me?

Spores with elipsodial to a litte fusiforme shape, with a very fine ornamentation, (19,5) 20,1 - 21,7 (22,5) × (10,2) 10,5 - 11,6 (12,1) µm; Q = (1,7) 1,8 - 2 (2,1); N = 78; Me = 20,9 × 11 µm; Qe = 1,9.

Asci with 8 spores, with croziers and blue all around with IKI, not only at apex.

Paraphysis cylindrical, slightly broad at apex and with abundant big VBs at least in the apex cell; but sometimes with pointed and curved apex.

Marginal cells similar to paraphysis without VBs and more capitated.

Thank you.

Miguel Á. Ribes

Hi Miguel,
this is already I. carneus. The species can vary in colour strongly how on the photos is to be seen. Noticeably under the Mikro are the big asci with the minutely verruculose spores, the septate and pigmentate paraphyses. The black balls in your preparation could be spores of Elaphomyces, with wild pig dung also not so incorrectly.
The dung of my fotos is from mouse, rabbit and guinea pig.
Greetings Peter.

Salut Miguel

No hay problema para Iodophanus, en realidad, el color puede ser variable dependiendo de la luz y la edad del hongo.

una salvación.

Michel.

Re : Iodophanus or Thecotheus 310116
Ok, thank's Peter and Michel.

I can't belive it, I was very confused with this species.

Anyway, do you have any explanation to rostrate-elongated paraphysis with big VBs, pictures 19 and 20 in Cresil Blue?

Best wishes.

Hi Miguel,
in my opinion the paraphysis are destroyed by CB.
Greetings Peter.

Hi Peter

No, no, please look pictures nº 14 and 15, both are made in water. In the new attached picture it is visible too.

Thank's a lot.

Hi Miguel,
now I see, what You mean.
KIMBROUGH, J.W., E.R. LUCK- ALLEN et R.F. CAIN (1969): Iodophanus, the pezizeae segregate of Ascophanus (Pezizales): Amer. J. Bot. 56 (10) writes:
Page 1889: "Excipulum-...Many cells become long, flexuous, hyalin, septate hairs varies with different species."
Page 1196: "Apothecia...with scattered, flexuosus, hyalin, septate hairs that are rounded at their apices, and many reach 50-80 µ in length;...".
This must be the elements, I have given to here actually no attention.
Greetings Peter.

Hi Peter

Sorry, sorry, sorry, I overlooked your answer.

Very interesting, probably thata are the cells I saw.

I haven't that paper and don't find it in the internet. Could you send it to me? please.

Best wishes.
