Palicella is a genus of crustose lichens in the family Lecanoraceae.[1] It contains five species.

Taxonomy[]

The genus was circumscribed in 2014 by lichenologists Pamela Rodriguez-De Flakus and Christian Printzen to accommodate the type species, (formerly placed in the genus Lecidea), and two closely related species, P. filamentosa and P. schizochromatica. Molecular analyses of these lichens revealed a monophyletic clade that is sister to representatives from two Lecanoraceae genera, and .[2] Two additional species were transferred to Palicella from Lecanora in 2019.[3][4]

Description[]

Palicella species have biatorine apothecia, which are often darkened (by the pigment cinereorufa-green), an exciple (a saucer-shaped rim around the hymenium) consisting of radiating, narrow hyphae with elongated lumina, and a hymenium with branched and sparsely anastomosed paraphyses. Other microscopic characteristics include an ascus with a broad axial body surrounded by a distinct darker staining layer, and ascospores with a narrow ellipsoid shape.[2]

Species[]

As of December 2021, Species Fungorum accepts five species in Palicella:[5]
