Herpotrichia?
Bernard Declercq, 05-01-2014 22:11
Bernard DeclercqHi to everyone,

Collected last week on decorticated branch of Betula pendula, in company of Chaetosphaeria pulviscula and Ascocoryne inflata: Ascomata superficial , gregarious, flattened globose, with central pore, 0,5-0,6 mm diam., 0,35-0,4 mm high, black, immersed in a dense dark brown subiculum. Asci bitunicate, 8-sp., rounded apex, arising from croziers, 113-139x11,5-12,5 µm.Paraphysoids numerous, filiform, 1,5 µm diam., anastomosing above the asci.
Peridum surface a dark brown textura angularis; subiculum composed of dark brown 4-5 µm diam. hyphae.
Could this be Herpotrichia alligata?

Best regards,
Bernard

Hi Bernard,


You miss ascospores in the description.

Re : Herpotrichia?

H. alligata is possible. Perhaps you should look towards H. herpotrichoides too.

Re : Herpotrichia?
Bonjour Alain,

Ah, oui .... les voici : "Spores fusoid, 17,5-21x6-6,5(7) µm, 1-septate, strongly constricted, smooth, hyaline, with (1)2 large LBs per cell (measured within the asci). "
J'ai donc pas vu des spores mûres ce qui rend la tâche bien difficile.
Mais en effet, ta proposition pourrait mieux convenir. J'ai bien observé la pore centrale des ascômes, ce qui serait caractéristique selon Mme Barr et il faut mieux être prudent avec l'introduction de noms d'espèces étranges à notre continent.
Merci pour ton avis.

Bernard
