En escama de cono de Abies sp.
Javier Ormad, 20-06-2011 18:40
Javier OrmadEn escama de un cono, de abeto ornamental. Hasta 2 mm de diámetro. He mirado varias ascas pero no veo ápice azul ni croziers, pero sin seguridad, de hasta 38-70 x 4.5-5 micras. Ascosporas lisas con vacuolas simples en los extremos esporales y en alguna madura un septo central, de 9-14 x 1.5-2.5. Parafisis con multiples VBs, así como los pelos, romos con inclusiones y con ornamentación. Excípulo ectal con células angulares. Células del pie con estructura prismática.
Ya sé que la información aportada no es muy abundante, pero tal vez por el hábitat, lo teneis identificado

On scales of a cone, ornamental spruce. Up to 2 mm in diameter. I've looked SEVERAL ASCI but I DO NOT see blue apex IN IKI or croziers, but without security,  ASCI up to 38-70 x 4.5-5 microns. Ascospores smooth with SIMPLE VACUOLES AT THE spore ends and SOMETIMES WITH a central septum mature, of 9-14 x 1.5-2.5 microns. Paraphyses with multiple VBs, as well as hairs, blunt WITH inclusions and ornamentatED. Ectal ExcípuUM COMPOSED OF angular cells. STIPE cells with prismatic structure.
I know that the information provided is not very abundant, but perhaps WITH the habitat, you CAN IDENTIFY IT

Dear Javier

from the micros I think this is a Lachnum, but from macroscopy this is quite improbable. You figured whitish and yellowish apos, is that variable or a matter of photography? What is the colour? And do the VBs in the paraphyses have a distinct yellow colour?

Lachnum papyraceum could be an option.

With help of Raúl, sent a better translation. The Apos had that color, macro photo, addiction is the processor that makes the photo to incandescent. The VBs are hyaline .......... Cyathicula?

Re : En escama de cono de Abies sp.
Ih yes, I mistook the asci for paraphyses. Now, but with a t. angularis it cannot be  Cyathicula.  The only idea I now have is Rodwayella citrinula. But that species is only known from monocots.

Re : En escama de cono de Abies sp.
Hi there,

Zotto may not have noticed the hairs. This is certainly not Rodwayella citrinula, it does not have hairs.
I got to disagree of its substrates. It is claimed rare here, but I regulary find it on anything else besides grasses. This year twice, on propably Urtica and maybe Anthriscus or something like that.

Could this be some Lachnum? Are the paraphyses lanceolate?

Re : En escama de cono de Abies sp.
Thanks Marja, you are right, I forgot the hairs. It seems a quite unknown fungus then.

But I also made the mistake of the paraphyses: they are asci.

Re : En escama de cono de Abies sp.
I first suggested Cyathicula to Javier because of the macro (white ones, yellow colours are not real) and because of the VBs in paraphyses and hairs, but not thought about ectal excipulum composition.
Any Ciliolarina or Cistella with such VBs and spores?
I will try to study it if Javier has more samples.

Raúl 

PD: Good! I can see the discussion below while writing!

Re : En escama de cono de Abies sp.
Hi
I studied two apos of Javier´s find and all recalls to Cyathicula. I have not been capable to find asci... they seem to have vanished. So no info about croziers. I have seen some blue dots in IKI, but not sure if they belong to the asci tips. Ectal excipulum of textura prismatica and oblita, very gelatinized. Scattered crystals. Also I have not found spores of the Cyathicula. If somebody wants more images, just ask me for them.

Re : En escama de cono de Abies sp.
Good, and yes, now it's clearly Cyathicula, very typical! The brown exudate might tell for C. cacaliae. The blue dots are certainly apical rings.
