Trichothecium roseum?

On the bark of a living Acer pseudoplatanus I found a number of white colonies of Hypho's.


Some hyphae had swollen tips. The conidia were hyaline, 1-septate and measured 31x14µ.


Could it be Trichothecium?

Re : Trichothecium roseum?
Hallo Marc,

La mesure des conidiies correspond plustôt à Trichothecium inaequale Massee & Salmon. Les mesures dans la clé de Seiffert qui traite les espéces sur excréments donne 24-30 x 15-20 µm.

Re : Trichothecium roseum?

Jacky,


Thank you for your answer but inaequale seems to be coprophilous and has a larger sporewidth. The conidia I measured were between 11 and 14µ.
