Hi friendsI studied this dry and dead inoperculate and hemiamyloid cup-shape fung, about 1 cm of diameter. Collected on 10/3/2018, at floor with needles of Pinus.
Asci cylindrical, 8-spored, hemiamyloid and with croziers.
Spores cylindrical to slightly alantoid, without LBs (dead state), (7,9) 8,7 - 10,6 (11,3) × (2,8) 3,1 - 3,7 (3,9) µm; Q = (2,2) 2,5 - 3,1 (3,8); N = 39; Me = 9,5 × 3,4 µm; Qe = 2,8. Spore edge looks like dextrinoid, it is slightly red, similar to spores of Ombrophila hemiamiloidea.
Paraphysis cylindrical without VBs.
Ectal excipulum with textura gelatinosa. Medullar excipulum with a textura mixed between angularis in the upper and prismatical in the lower part.
Thank you.
I assume the spores are without oil drops, but did you check that in KOH?
To be sure that VBs are absent seems difficult to me when only a dead specimen is at hand.
My only idea is a Discinella.
I assume it is from Spain?
No, I didn't check the spores with KOH, because all the study is made with dead material. The table spores are with water and IKI. Do you think we can see any different character with KOH?
Sorry, it is from Canary Islands, Las Palmas de Gran Canaria.
Discinella? Perhaps a Phaeohelotium too?
Thanks a lot
In fact, oil drops are often masked in dead spores by the plasma but appear in full strength when mounting in KOH.
How old is the sample so that the spores are not further alive?
Phaeohelotium does not have such gelatinised excipulum.
It was collected at 10/3/2018.
Thanks.
You were right, Zotto, the spores with KOH have oil drops, so Discinella sp. (Picture attached)
Thanks a lot.
Thanks again
