Propolis viridis
Miguel Ángel Ribes, 04-04-2009 11:37
Miguel Ãngel RibesBuenos días
¿Podría ser esto Propolis viridis? Según el CABI, P. viridis es sinónimo de P. versicolor, y a su vez, el nombre actual es P. farinosa. Sin embargo, la mayoría de las publicaciones de P. versicolor tienen el himenio blanquecino o de blanco sucio a blanco azulado, pero nunca un color verde-azulado tan intenso. Las medidas esporales de P. versicolor podrían coincidir con esta recolección en cuanto a longitud esporal, pues hay una gran variación en la literatura, pero son más estrechas, entre 5-7 µm, y además son mayoritariamente alantoides, mientras que las nuestras tienen entre 8-11 µm y son mayoritariamente elipsoidales. Con las claves de Baral podría descartarse P. versicolor, por el color persistente verdoso-azulado; por las esporas bigutuladas iríamos a P. viridis o bien a la recolecta de Propolis sp de Madeira (HB 5961c E). Las medidas de las ascas no coinciden con las de P. viridis, son bastante más grandes y cercanas a P. versicolor o a la recolección de Madeira.

Saludos, Miguel Ángel
Good morning
Could be this P. viridis? According to CABI, P. viridis is a sinonim of P. versicolor, and the actual name is P. farinose. But in the books P. versicolor has a more or less white himenium, but never green-blue so intense. Sporal measurement of P. versicolor are similar in length to our record, but are narrow (5-7 µm) and are allantoids; our sporal length are 8-11 µm and usually ellipsoid. With Baral key I think it is not P. versicolor, cause de the green-blue color; with bigutulated spores I arrive to P. viridis or to the record of Propolis sp from Madeira (HB 5961c E). Asci measurement don’t match with P. viridis ones, are bigger and nearest to P. versicolor or Madeira’s one.

Best regards, Miguel Ángel

Re:Propolis viridis
Dear Miguel

I am not aware if I ever saw the original description of P. viridis. Maybe I only assumed that it has typically non-allantoid spores (which I illustrated from several collections) much shorter than P. versicolor/farinosus. Surely this all is not only one species. But spore size varies among the greenish populations which only occur in warmer, +/- mediterranean climates.

Re:Propolis viridis
My collections are on wood of Pinus halepensis, Quercus ilex, Erica arborea, Olea, Arbutus, Myrtis communis, Castanea, Pistacia, Phillyrea.

What is the substrate in your case, Miguel? Do you have a microphoto of the spores?

Hi Zotto

Of course, I have a full micro study, which I attached in my first message. I attach it again. My substrate is Eucaliptus globulus.

Zotto: just below the photo, he's uploaded a pdf file with description and good spores, paraphyses... photographs. Host is indicated: Eucalyptus globulus.

Re:Propolis viridis
You are right, spore size fits best to this Madeira collection. I just looked for the original description of P. viridis, and I find in Saccardo a spore size of 16-17-x 5-7 µm, so much smaller than in P. versicolor, and well matching several of my drawings. - click catalogues, Saccardo 14: 806

Spore size variews somewhat in Propolis, but your and the Madeira collection might well represent a different species. Could you perhaps have a look for it, maybe you find it repeatedly, then please always look for spore size and contents.

You wrote "material fresco", but your images all show dead elements. Did you make the photos last year? Did you squash the mount very strongly?

Re:Propolis viridis
Dear Zotto

Microscopical photos are made from fresh material at 29/06/2008, so 11 days later from pick up. Please, see again the attached file, point 2 (spores), I have change some photos. I think it is posible to appreciate 2 big gutules and another small one.

Thanks again.

Re:Propolis viridis
Yes, on your plate 2, lower left image, are two asci with livin spores. The two larger LBs are also seen in some dead spores, anyhow I prefer the living, because LBs may easily fuse in dead spores.

Re:Propolis viridis
Ok, Zotto, thanks again.

I will be again at Tenerife from 13 to 21 june. I will look fot it. If I found it, I will send you photos and spore size.
