Niebla isidiaescens

The type collection of Niebla isidiaescens ^[2] was inferred to have divaricatic acid^[3] based on the circumscription given by Bowler and collaborators.^[1] However, it is a mixed collection^[4] of approximately 20 specimens of mostly two species, N. isidiaescens and Vermilacinia paleoderma, and loose branches of a third species, Niebla contorta,^[5] the identification for the latter assumes that the thalli parts contain divaricatic acid.^[3] This association and the broad lobes of the thallus may indicate that N. isidiaescens was derived from N. contorta, in contrast to Niebla flagelliforma.^[3] Niebla usneoides is a similar species distinguished by the absence of pycnidia and presence of sekikaic acid.^[3]
