Amphisphaeriales
Enrique Rubio, 17-07-2023 20:33
Enrique RubioThese blackish, effuse stromata have immersed perithecia up to 0.5 mm in diameter, visible as obtuse swellings on the wood, perhaps of Acer. The long asci have a discoid and amyloid apical apparatus and the spores, with smooth walls, are light-coloured for a long time and then gradually become olivaceous and finally dark brown, without gelatinous sheaths or germ slits.
I suppose it could belong to the genus Amphisphaeria, but I can't find any species well adapted to these characters.
Perhaps someone might have some idea that could help me.
Many thanks in advance.
