REMARKS
Riccardia digitiloba is a dioicous, widespread neotropical species that was recorded from Guadeloupe byPagán (1942) based on material from Bains-Jaunes (Lefèbre & Marie s.n.) and Petit Bourg (Questel 1555, PC). We have not seen these specimens and are unable to confirm the occurrence of R. digitiloba in the French Antilles. The species is recognized by the small-celled epidermis (epidermis cells 3-4× smaller than inner cells) and the delicate, pinnate to dichotomous thalli with linear, wingless or rudimentarily winged branches producing gemmae at the tips. The gemmiparous branches are sometimes tapering to narrow tips ( Gradstein & Reeb 2018b).
