Endoxyla (?) o Pinus sylvestris wood
Enrique Rubio, 28-10-2014 20:29

Hi to all

My friend F.J. Balda sent me this fungus growing on very wet, semirotten, wood of Pinus sylvestris that makes groups of inmersed and blackish perithecia 0.5-0.6 mm high inside + or - developped blackish stromata. Only the blackish and roundish papilla erumpent.

Asci long-stipitate up to 155 x 9 micr., with a refractive, small, IKI negative apical apparatus. The greenish-brown mature ascospores have a non-septate dark cell with an apical pore and an small hyaline cell under the wich we can to observe a very small hyaline papilla (?).

If this fungus belongs to Endoxyla only E. xanthostroma is close, but the lack of yellowish tissues and the hyaline papilla of the ascospores don't fit with this species.

Any idea?

Thanks again

Hi Enrique,

E. xanthostroma is a good option, you said it. On the fourth photo, we can see yellow tissues, do you agree ?

The other features fit almost well with E. xanthostroma.

Hi Alain

Really this is a photographic artefact because there are not yellowish tones in the wood or stromata. By the other hand Untereiner doesn't describe the small but conspicuous hyaline papilla on the ascospores

Dear Enrique,

in fact she does mention the "cellula hyalina" (p. 305 and figs. 21-22).

Hi Martin

The hyaline cell was described, and it was drawn by  Untereiner, but not the small hyaline appendage under this cell!
