Pannaria minutiphylla is a species of lichen in the family Pannariaceae,[1] described as a new species in 2013 by Arve Elvebakk. The species is similar to Pannaria phyllidiata, but can be distinguished by its smaller phyllidia and ascospores that are elongated to ellipsoid.
Pannaria minutiphylla was formally described by Arve Elvebakk in 2013. The specific epithet minutiphylla refers to the species' numerous small phyllidia.[2]
Description
The lichen has a foliose (leafy) thallus, that is either corticolous (bark-dwelling), foliicolous (leaf-dwelling), or occasionally saxicolous (rock-dwelling). It forms rosettes of 3–15 cm (1+3⁄16–5+7⁄8 in) in diameter. The lobes are irregularly to somewhat dichotomously branched. These lobes are discrete in peripheral parts of the thallus, and imbricate towards the centre. The upper surface of the thallus is pale greyish-green when fresh and dry, turning salad-green when moist, and gradually turning chestnut brown after storage. The upper cortex is 25–40 μm thick. Phyllidia are common along the margins, and the photobiont layer is composed of more or less spherical cells. The medulla is mostly white, with a dark brown lower part.[2]
Apothecia are absent, sparse, or common, with a rufous-brown disc. The hymenium is colourless and intensely IKI+ blue. Proper ascospores are hyaline, non-septate, and regularly elongate to ellipsoid.[2]
