On Populus outer bark
Elsa Sousa, 04-07-2017 23:15
Good evening,

Spores:

(57.1) 58.4 - 67 (72.9) × (14.9) 15.9 - 20.4 (21.2) µm
Q = (2.9) 3.2 - 3.9 (4.4) ; N = 16
Me = 63.6 × 17.8 µm ; Qe = 3.6

multiseptate and guttulate.

I would appreciate any help.
Thank you very much.
Regards,
Elsa

Hi Elsa,

I would look around Navicella.

Best wishes,
Gernot

Re : On Populus outer bark
Thank you Gernot, I don't find any description or keys for Navicella. Spores are very close to Navicella pileata (the only one I find something about), but I don't know if it could be this one, could it be?

Re : On Populus outer bark
Hi Elsa, the only key I know is in M.E.Barr's "North American flora. Series II". But key is a great word for two species. There seems to be another species, N. xinjiangenis, described by Yuan & Zhao (1994) from China. It seems to be close to N. pileata and N. elegans, but has narrower and longer asci [(95-)150-265(-300) x (16)-20-30(-40) in N. pileata vs. 287-355 x 14,3-17,5 µm and narrower ascospores: 47,5-62,5 x 10-12,5 µm, 5-7 (mostly 7) septate.

Klaus

Re : On Populus outer bark
Thank you Klaus for your explanation and keys. With this I think that I can call it N. Pileata at least for now.
