Acrospermum spec. on Cytisus scoparia

Marian Jagers, 18-04-2023 09:59

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,
Marian Jagers (The Netherlands)
