Hello friends,


what do you think about Otidea cf. umbrina ? I found this one under Picea sp., Alnus glutinosa and Pinus sp..

Fruitbody 30-50 x 20-90 x 20-90 mm


Spores (12)13-16(17) x 6-7 µm


Regards


Pavol

Re : Otidea cf.umbrina

Hi there!

To me it looks like O. mirabilis as I can see some bluish-violaceous shades in the young ascoma of the first fruitbody. The only other species it can be is O. bufonia, with brown crystal deposits in the medullary excipulum (in water or Melzer). You should check that to rule it out.

At least in Northern Europe O. mirabilis appears to only occur in calcareous localities.

Cheers!

Ibai.

Re : Otidea cf.umbrina
Hi Pavol,

Actually it looks like the medullary excipulum has the sphaeroid brown crystaliized deposits characteritic of O. bufonia. Could you get a photo with the brown crystals in focus?

Cheers!

Ibai.

Re : Otidea cf.umbrina

Yes, they look like those of O. bufonia. We have also seen O. bufonia specimens with light bluish shades when young and thus reminiscent of O. mirabilis, which seems to be the case. We have never seen sphaeroid crystals like those you have photographed in O. mirabilis.

Thanks!

Ibai.
