Hier j'ai récolté ces petits disco sur feuillu décortiqué (peut-être Salix). C'est le bois rougi qui a attiré mon attention, j'ai pensé que ce serait un bon critère pour la détermination, mais je n'ai rien trouvé.
Fructifications de forme conique, diam 0,5 mm, marge festonnée en viellissant.
Extérieur gris, furfuracée de brun-jaunâtre. Hymenium brun olivacé.
Asques J- (Melzer), pas de croziers, 4,8 x 37µ.
Spores ovoïdes lisses, non septées, env. 1,6 x 4,5µ.
Quelqu'un a-t-il une piste de recherche à me suggérer ?
Michel.

Re : Bois rougi
Yes, this is a Hyphodiscus, probably H. hymeniophilus. The asci should have a minute amyloid apical ring, but in Melzer the reaction can easily be suppressed, it is hemiamyloid, so either you must pretreat for some seconds in KOH and then test MLZ (after washing), or test IKI (Lugol).
the fungus has a conidial state (Phialophora-like: Catenulifera rhodogena) which also causes the red stain. The connection is proved, but Index F. does not show the connection.

Re : Bois rougi
Hello Michel,
a track could perhaps be Hyphodiscus hymeniophilus
Best regards, Lothar
