Anamorph on Phragmites australis
Miguel Ángel Ribes, 11-07-2023 08:42
Miguel Ãngel RibesGood morning

A friend of mine found this possible anamorph on Phragmites.

Small cottony-looking fruiting bodies that develop on Phragmites australis stems. Several specimens of Trichobelonium kneiffii (formerly Mollisia retincola) have been identified on the same stem. The fructifications are grouped in numerous specimens that form large spots on the stem, of an intense purple color (photos 1 and 2). Before ripening they appear to have a whitish coloration.

Under the microscope, the fructifications consist of a base formed by a group of hyphae grouped as a stem, on which a small spherical body develops (photos 3 and 4). When ripe, the stem opens in the shape of a fan and the spherical body is dispersed into small rounded cells (photo 5), which occasionally appear to form small chains. All the observed structures have a very intense purple coloration.

Thank you in advance.

Miguel Á. Ribes

Hi Miguel Angel

I overlooked this post but cannot really help. Although Mollisia has various anamorphs, such synnemata are unknown to me (which says not much). The heighgt is very low? Perhaps 100 µm? And the conidial diameter?
