Marja PennanenHello forum,these are up to 0,4 mm wide.The spores
Hello forummembers,
I found several FRB's in two different places (distance +/- 500 m) on the dried banks of two different brooks
a) 24/06/2015 Staatsbos Sevendonk Turnhout, Belgium
b) 26/06/2015 Winkelsbroek Turnhout, Belgium
Macroscopic features:
Substrate: found on the dried banks of two brooks on a muddy soil full of plants and herbal roots (a = bare soil, b = soil full of leaf litter).
FRB: sessile, flat to cushion-shaped with diameter smaller than 5 mm; dark yellow to orange colored with a jagged edge slightly paler, alone or in bundles (squeezed together)
Microscopic features (all dimensions in water): fresh material in water and in Melzer.
asci : cylindrical, uniseriate; IKI-; croziers present
a) 267,47-294,88 x 15,04-23,32 µm
b) 217,36-261,03 x 15,26-24,11 µm
spore: hyaline, globose tot broadly ellipsoid with spines:
a) 16,23-17,64 x 13,23-16,14 µm; spines: 1,79-3,42 µm; Q= 1.016
b) 15,93-18,91 x 17,03-18.06 µm; spines: 2,89-4,37 µm; Q= 1.11
Paraphyses : 320 x 5.8 µm, top irregular clavate (8-12 µm) with pale orange content; slender, filiform with septs
Texture: globulosa, angularis
Marginal cells: 147-170 x 21-30 µm; elongated cells with 5 septs, constricted en rounded top.
After reading about the genus Ramsbottomia (Dieter Benkert, Nicolas Van Vooren and Yannick Mourgues, I think it is Ramsbottomia crechqueraultii.
Being an amateur I am somewhat confused. The difference between globose and broadly ellipsoid, the difference in spore length of 1 to 4 µm is susceptible to interpretation. Furthermore in Mycobank the current name is Lamprospora...
I hope I have got the right determination? I still have to learn much and accept that not everything is clarified!
Kind regards,
François
Votre champignon, avec ses spores échinulées correspond parfaitement à Ramsbottomia crechqueraultiiI Il n'entretient aucun rapport avec les mouses même si, parfois, on en trouve quelques unes à son voisinage. De ce fait, il a été exclu des Lamprospora.
Le genre Ramsbottomia a été créé pour ces espèces à spores rondes (ornées d'épines voire de très fortes épines), non muscicoles, pouvant présenter quelques poils comme sur votre photo
Amicalement

Je vous remercie beaucoup pour votre réponse rapide.
Cordialement,
François
