Hello,
Anyone familary with the genus Acrospermum knows more about this found? The substrate is quite different from that of the most common species, A. compressum or A. graminum.
Growing in a small group, on small, dead twig of Cytisus scoparia. Ascoma about 0,9-1,5 mm high, dark yellowbrown.
Asci and spores plentiful but difficult to measure. Some asci are at least 350 µm long and they are about 3 µm diam., thick-walled, J-.
Parafysen: filiform.
Excipulum: the outher wall brown, textura prismatica.
Kind regards,
