Boudiera tracheia 280815 281

Miguel Ãngel RibesGood night again

This small (2,5-3 mm) Boudiera was growing in a very wet and small alpine river in Pyrenees.

Asci 8-spored, euamyloid all around, without croziers, (350,8) 354,8 - 441,7 (460,3) × (30,1) 32,4 - 46,5 (48,5) µm; N = 32; Me = 402,4 × 40,1 µm.

Round Spores, with great conical spines, sometimes bifurcated at apex, (22) 23,8 - 25,2 (26,1) × (21,9) 23,7 - 25,2 (25,7) µm; Q = 1 ; N = 40; Me = 24,5 × 24,3 µm ; Qe = 1 without ornamentation. Spines (4,4) 4,8 - 5,9 (6,5) µm; N = 69; Me = 5,4 µm.

I don't find another species more than Boudiera tracheia.

Thank's in advance.

Miguel Á. Ribes

Re : Boudiera tracheia 280815 281
Hi.
Is it possible to see some spores in CB?

Re : Boudiera tracheia 280815 281
Gracias Plácido, lo miraré esta tarde.

Hi Nico. No, sorry, with this spectacular ornamentation in water I didn't think to use CB, but I have dried material. Are you thinking about another species? Do you want to see an special detail in the decoration with CB? I could try it.

Thank you.

Re : Boudiera tracheia 280815 281
Bonjour Miguel,
Avec des spores munies d'épines aussi fines et aussi longues, je ne vois rien d'autre que B. tracheia. Terrains très humides avec de petits Juncus ?

Re : Boudiera tracheia 280815 281
Bonjour Gilbert

Yes, at alpine place, in a very, very humid slope of a small stream, between mosses, with Juncus, Aconitum and another small herbs, growing near to Scutellinia minor.

Merci.
