Article
The association between epizoic algae and animals is well known, and turtles are among the animals that most commonly host epibiont communities. The most studied algal component of the epizoic communities found on turtles is represented by diatoms, while other algal taxa, like the Rhodophyta, are less investigated. During a survey started to study...

Article
A brief history of both nomenclature and taxonomy of ‘Callithamnion codii’ is presented. From the nomenclatural point of view, the implications deriving from considering it as validly published or not are presented. From the taxonomic point of view, the conspecificity of Colaconema codii and Colaconema caespitosum is reaffirmed.

A critical re-examination of both recent and historical herbarium specimens from the Mediterranean Sea attributed to Gelidiella ramellosa highlighted that previous identifications were incorrect. Our investigations have demonstrated that the examined specimens actually belong to the genus Parviphycus; some of them must be attributed to the recently...
Article
Attention is called to Ulvaceae invalidly described by Bliding in 1960 and 1963, due to his failure to indicate Types. The following new taxa Ulva croatica, Ulva mediterranea, Ulva splitiana, Ulva flexuosa var. linziformis, Ulva linzoides, Ulva blidingii, Ulva flexuosa [subsp. paradoxa] var. profunda and Ulva prolifera subsp. blidingiana to replace...
Article
Attention is called to the failure of P.J.L.Dangeard to designate Types for essentially all of his new algal taxa proposed after 1957. Designation of Types was a requirement of the Melbourne Code starting 1 Jan., 1958. So the numerous names of both genera and species are invalid. Some of Dangeard's species were later transferred to other genera or...
Article
Feldmann (1970: 249), quoting the results of Hustede (1960), who had shown that Bryopsis halymeniae Berthold (1882: 497) was the gametophyte of a Derbesia sp. [1] , pointed out that this species could not belong to the genus Bryopsis differing from it in chloroplasts with no pyrenoids and gametes without a stigma. On that basis, as well as because...
Article
The new species Ulva ardreana is here proposed to replace Ulva bifrons, an invalid name because no holotype was designated in the protologue. The new species consists of two to three distromatic blades arising from a short stipe, and it is easily distinguished from the other blade-like Ulva species in having a remarkable diversity in both shape and...
