Observation 122539: Peltigera ponojensis Gyelnik
When: 2012-12-25
Who: zaca
No herbarium specimen

Notes: These specimens were observed in the same habitat than those in observation 121150, a side road barrier covered with moss.
After reading one more time the description of the species present in the British Flora, I arrived to the conclusion that only one species has these features: Peltigera ponojensis, though there it is mentioned that apothecia are rare. To get another point of view I follow the key in Pelt Lichens of North America by Jason Hollinger. Here are the steps that gave the same result:
Key to keys
photobiont blue-green
… at most lobulate
…….upper surface dull; rough or tomentose or pruinose at least near margins
……….. Key 4

Key 4: photobiont blue-green, at most lobulate, dull surface (canina group).
veins present; brownish to pale or dark gray
… surface tomentose or pruinose but never rough
…….. rhizines pointed; veins narrow, distinct, sharply raised near margin
………. lobes smallish; margins turned up; entirely pale below
…………… P. ponojensis
Therefore, this is my best classification for these specimens.
