Resultaten van de excursie naar De Diepen op 11 september 2021
Desmidiologische Mededelingen , Volume 7 p. 17- 20
During the excursion (see also Coesel's contribution in this issue) 116 taxa were recorded. Apart from Xanthidium fasciculatum, only a few rare species were found, possibly related to the still relatively high nutrient availability, the pioneer character and possibly also as a result of the regular drying out of the puddles in recent years. A taxonomically unclear taxon was a large Pleurotaenium, resembling both P. ehrenbergii and P. maximum.
