Hymenoscyphus calyculus 121015 236
Miguel Ángel Ribes, 10-08-2016 21:31
Miguel Ãngel RibesGood night

This Hymenoscyphus was growing on small herbs of Rumex scutatus. I think it is a common species, but is the first time I see it.

Asci 8 spores, with croziers, euamyloid and with a slight cover in the apex,  (114,8) 116,3 - 123,6 (126,3) × (9,9) 10,2 - 12,4 (13,4) µm; N = 19; Me = 120,3 × 11,4 µm.

Spores more or less navicular with a pointed end and rounded the other one, but sometimes with a small "teeth". Sometimes covered with a partial gelatinous shell, mainly in the acute end, (15) 16,7 - 20,9 (22,9) × (4,5) 4,8 - 5,6 (6,4) µm; Q = (2,9) 3,2 - 4,1 (4,9); N = 101; Me = 18,7 × 5,2 µm ; Qe = 3,6.

Paraphysis plenty of refractive VBs.

Thank you for your help.

No no, this is an interesting collection, nothing common. It has actually great similarities with H. calyculus, but I would never expect H. calyculus on herbaceous stems.

No idea about this sample, actually. H. calyculus I did not see since a very long time. It might be more frequent in the region of the Alps, but molecular research on it showed that populations with very different rDNA exist - the matter remained unsolved.

Que suerte tengo, si monto un circo me crecen los enanos., 2 de 2. I am sorry, I can't translate it to English. I have a third Hymenoscyphus to sent, perhaps tomorrow, I hope it will be a known species.

Thanks Zotto, another candidate to molecular studies.
