Observation 50240: Lecanora garovaglii (Körber) Zahlbr.

When: 2010-07-07

Collection location: Lewis River, Yellowstone National Park, Wyoming, USA [Click for map]

Who: Chris Parrish (kitparrish)

No specimen available

Identification: The rather long, “inflated and sinuous-plicate” lobes (Ryan et al., Sonoran Flora, vol. II, p.178) of this Lecanora indicate that it is Lecanora garovaglii, as suggested by Jason.

apothecia in L. muralis

Yes, when not competing with adjacent thalli, L. muralis should begin producing apothecia bsome distance ack from the lobe tips. However, if you find a colony of several growing together, or if you find it competing with other species, you can find it covered with apothecia right to the edge. In fact apothecia are generally quite abundant in this species. But always you should find a few lobe tips (it can grow a significant amount of lower cortex, enabling it to overgrow other competing lichens), and these are typically waxy-looking and somewhat concave, or at least with slightly thickened margins — a very different look from the folded to almost inflated appearance of L. garovaglii.

I looked through some Lecanora muralis photos, but all of them featured abundant apothecia clustered in the center … but maybe people went for those ones because they seemed more photogenic !

I’d say the lobes are too convex and folded to be L. muralis, which probably makes it L. garovaglii, but is there any way to be sure?
