Taxonomy

The type (biology) 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]

gollark: As a temporary solution it all got fed to one of our negative frequency trader machines, which will apply it to all financial markets simultaneously and thus keep it out of the way for a few years.
gollark: We tried feeding the capital into excess letters from the language models but then ran into Unicode concerns.
gollark: By some estimates, 3% of our processing power is spent on accounting.
gollark: No.
