Collection location: Forest near Elgin St., Pembroke, Ontario, Canada [Click for map]

Who: Paul Derbyshire (Twizzler)

No specimen available

In one photo, this lichen can be seen with Cladonia cristatella and a mushroom that may be Rickenella fibula.

In open meadow near mixed woods.

In the photo of the big clump, the branches are pale greenish but the branch tips seem tinged with pink. Fascinating.

Used references: Brodo’s L. of N.A.: Branching in 4’s with perforated axils. If it were more compact it might be C. stellaris; if the tips were “droopy” (and branched more in 2’s than in 4’s) it might be C. rangiferina. (Excellent photo!)
56% (1)
Recognized by sight: Looks to white to be C. arbuscula or C. mitis, like I thought it was.

That’d be the Cladonia cristatella that’s ubiquitous in the same area. The second photo shows this species’ presence more clearly with a lot of the characteristic red-tipped structures.

Did you notice? Arising from the moss is a spore-producing structure, looks light green in this photo, like a post-horn on end.
