Ulva flexuosa subsp. flexuosa Wulfen

3.4 Ulva flexuosa subsp. flexuosa Wulfen

The only sample of Ulva flexuosa subsp. flexuosa Wulfen (SAM1165; Figure 4 View Figure 4 ) was collected at the Lido station (suffi- cient MaQI Index ) in the spring of 2019.

According to Cormaci et al. (2014), U. flexuosa colonizes several habitats, both sheltered and exposed; however, it is more common in brackish lagoon environments and in canals with poor water exchange ( Cormaci et al. 2014).

In the Lagoon of Venice, Pignatti (1962), reported U. flexuosa (as Enteromorpha flexuosa ) as a species characteristic of the photophilous community of Fucetum virsoidis, established on the north-eastern Adriatic rocky coasts in the presence of large tidal ranges, low average temperatures, low salinity, and eutrophic waters ( Pignatti 1962).

Three subspecies of U. flexuosa were reported for the Lagoon of Venice by Sfriso et al. (2009): U. flexuosa Wulfen subsp. biflagellata (Bliding) Sfriso et Curiel , U. flexuosa Wulfen subsp. paradoxa (C. Agardh) M. J. Wynne and U. flexuosa Wulfen subsp. pilifera (Kützing) M. J. Wynne.
