124987CE6314FFDD8E33FE61F63BF969.taxon	description	According to Sfriso et al. (2023), U. australis is now the most widespread NIS in the Lagoon of Venice. It is possible that the species growth is being aided by the decrease in the lagoon ’ s trophic conditions. This Indo-Pacific species was introduced in the Mediterranean Sea by mollusc farming and recorded, as U. pertusa Kjellman, from the Thau Lagoon (France) (Cormaci et al. 2004), the Gulf of Naples (Flagella et al. 2010) and the Lagoon of Venice (Manghisi et al. 2011). ITS 1 and rbc L data of U. pertusa from Spain suggested their synonymy with U. australis (Couceiro et al. 2011). Wolf et al. (2012) confirmed the presence of U. australis in the Lagoon of Venice by analyses based on rbc L and tuf A markers. Womersley (1984) reported U. laetevirens among synonyms of U. australis, pointing out that the sizes of cells of the lectotype of U. laetevirens were superimposable to those of U. australis. Subsequently, Phillips (1988) considered U. australis to be a synonym of U. rigida. Furthermore, molecular investigations performed by Kraft et al. (2010) have demonstrated that U. rigida was distinct from U. australis. The recent phylogenetic analysis of rbc L gene sequences by Hughey et al. (2021), supports the taxonomic synonymy between U. laetevirens and U. australis assumed by Womersley (1984). In the Lagoon of Venice, Sfriso (2010 a), probably following Phillips (1988), listed U. australis among synonyms of U. rigida. Santarelli (1931) listed Ulva lactuca f. laciniata (Wulfen) J. Agardh from Trani (Adriatic Sea), indicating the species is synonymous with U. australis Kützing; as reported by the author, this species was collected in Adriatic Sea also by Van Den Bosch, Kützing and Hauck. Whereas Schiffner (Schiffner and Vatova 1938) labelled samples of U. lactuca var. laciniata (Wulfen) J. Agardh, including also the “ f. australis ” in the “ Vatova and Schiffner ” collection, hosted at the Natural History Museum of Venice. Observing these herbarium samples in the “ Vatova and Schiffner ” collection, we do not exclude the possibility that U. australis was already present in the Lagoon of Venice in the early 1990 s.	en	Minicante, Research Article Simona Armeli, Melton, James T., Spagnuolo, Damiano, Manghisi, Antonio, Genovese, Giuseppa, Morabito, Marina, Lopez-Bautista, Juan (2025): A DNA barcode inventory of the genus Ulva (Chlorophyta) along two Italian regions: updates and considerations.

124987CE6312FFD18E33FB3BF4D6F904.taxon	description	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.

124987CE631DFFD38D83FF52F13FFB4A.taxon	description	According to Hughey et al. (2021), U. lacinulata is the correct name to apply to the globally [excluding European] distributed species that was previously but incorrectly known as U. rigida. In Europe, both the genuine U. rigida and U. lacinulata occurs; however, according to the distribution based on DNA sequences reported by Hughey et al. (2021), at present, U. rigida appears to be restricted to the European north-eastern Atlantic Ocean, whereas U. lacinulata – variously reported either as U. rigida or U. laetevirens – is distributed further in the Mediterranean Sea. In the Lagoon of Venice, U. lacinulata was already reported as U. lactuca f. lacinulata by Schiffner and Vatova (1938) and Pignatti (1962). Sfriso (1987) and later (Sfriso 2010 b; Sfriso and Curiel 2007), referring to Bliding (1968), listed U. lactuca f. lacinulata as a synonyms of U. rigida. Furthermore, the comparison of the sequences from Tunisia published by Miladi et al. (2018) showed that U. lacinulata was previously labelled as U. laetevirens in Monastir, Sousse and Tabarka sites (Figure 4) for the same reason stated above (Kirkendale et al. 2013).	en	Minicante, Research Article Simona Armeli, Melton, James T., Spagnuolo, Damiano, Manghisi, Antonio, Genovese, Giuseppa, Morabito, Marina, Lopez-Bautista, Juan (2025): A DNA barcode inventory of the genus Ulva (Chlorophyta) along two Italian regions: updates and considerations.

124987CE631DFFD28D83FABDF115FCE8.taxon	description	According to Hughey et al. (2019), the holotype of U. lactuca is the species previously called U. fasciata in the subtropical area and U. lobata in the eastern Pacific Ocean. The current distribution of U. lactuca confirmed by DNA sequences is in the eastern (Australia) and northern (India) Indian Ocean, central (Hawai ’ i, USA) and temperate southeast (Chile, Peru), southwest (Australia), and northwest (South Korea, Japan) Pacific Ocean, warm temperate eastern (Azores) and western Atlantic Ocean (including the Gulf of Mexico and Atlantic Florida, USA) and the eastern (Egypt, Israel) and western (Italy) Mediterranean Sea (Hughey et al. 2019). The presence of this species in the two sites in Italy, in Capo Peloro Lagoon and the Lagoon of Venice (Miladi et al. 2018), might be due to recent introductions as both sites have anthropogenic impacts, also according to Hughey et al. (2019). However, their introduction date might be older. The first record of U. lactuca in the Lagoon of Venice dates to 1987 as U. fasciata (Sfriso 1987); in 1938, Schiffner reported as “ U. fasciata Delile […] has also been collected in the Adriatic at Makarska (Dalmatia); is rare and is often confused with U. lactuca ” (Schiffner and Vatova 1938). 3.7 “ Ulva linza / procera / prolifera ” Samples of “ U. linza / procera / prolifera ” (Figure 4) were collected in spring at the ST 10 in 2018 and at Celestia station in 2010 (Table 1), with a poor and good MaQI Index, respectively. The latter specimen had previously been identified by Armeli Minicante (2013) as U. linza (Supplementary Table 2). ITS sequence data obtained by Brodie et al. (2007) showed Ulva procera (Ahlner) Hayden, Blomster, Maggs, Silva, Stanhope et Waaland as conspecific with typical Ulva linza Linnaeus. Furthermore, Kang et al. (2014) note that several authors regard U. procera as a separate species from U. linza (Heesch et al. 2009; Kirkendale et al. 2013; Saunders and Kucera 2010). The lectotype of U. prolifera O. F. Müller is a drawing in Müller (Müller 1778), the epitype was designated and sequences for the ITS- 2 and 5 S rDNA spacer regions generated. The ITS- 2 sequence of this specimen was not made publicly available but was reported to be identical to a previously published sequence with GenBank accession number AJ 012276 (Kuba et al. 2022). To date, there are two major opinions (Cui et al. 2018) on the classification of U. prolifera based on molecular markers. One point of view is that the true U. prolifera is included in the linza – procera – prolifera (LPP) complex clade (consisting of U. linza Linnaeus, U. procera (Ahlner) Hayden, Blomster, Maggs, Silva, Stanhope et Waaland, and U. prolifera), and the other is that U. prolifera forms a separate clade that includes specimens from Scotland and Ireland, while the entire LPP complex clade is U. linza. Using ITS and 5 S rRNA gene spacer region as barcode markers on Ulva LPP complex, U. procera was recently reduced into synonymy under U. prolifera by Cui et al. (2018). Based on this synonymy, Kuba et al. (2022) identified U. procera specimens from San Juan Islands (USA) on the basis of ITS- 2 sequences, that were 1 – 2 base pairs different (0.47 – 0.93 %) from that of the U. prolifera epitype. However, the San Juan Islands specimens molecularly identified as U. prolifera, were not branched tubes, the characteristic morphology of the species, but distromatic blades that became tubular where they were basally narrow near the point of attachment. This latter morphology has been identified as U. linza in the Northeast Pacific (Kuba et al. 2022). In the light of these observations, the authors suggest that the concept of U. prolifera needs to be expanded to include blade-form thalli. The LPP-clade has been a troublesome group, and morphology does not appear to be helpful because this clade is known to have wide-ranging morphologies from linza - like to prolifera - like. Additionally, only tuf A sequence data was obtained for our samples since this has shown to be an excellent barcoding marker for green algae, and therefore, we were not able to compare this sequence data with the 5 S rRNA and ITS sequence data from the epitype. For these reasons, we choose to call the clade “ U. linza / procera / prolifera ” as the designation for the samples from the Lagoon of Venice identified in this study. Multi-gene or genomic analysis should be considered in the future.	en	Minicante, Research Article Simona Armeli, Melton, James T., Spagnuolo, Damiano, Manghisi, Antonio, Genovese, Giuseppa, Morabito, Marina, Lopez-Bautista, Juan (2025): A DNA barcode inventory of the genus Ulva (Chlorophyta) along two Italian regions: updates and considerations.

124987CE631CFFD28DADFC0BF173F907.taxon	description	However, colonization by this species had not been detected in the area (Flagella et al. 2010). U. ohnoi is commonly regarded as a NIS, having a disjointed distribution and being recorded in highly disturbed sites. However, its presence in the Mediterranean Sea, as well as in other sites, might be underestimated and its actual distribution, as well as its native range, might be far different from what presently known (Miladi et al. 2018).	en	Minicante, Research Article Simona Armeli, Melton, James T., Spagnuolo, Damiano, Manghisi, Antonio, Genovese, Giuseppa, Morabito, Marina, Lopez-Bautista, Juan (2025): A DNA barcode inventory of the genus Ulva (Chlorophyta) along two Italian regions: updates and considerations.
