Observation 130311: Pannoparmelia angustata (Pers.) Zahlbr.
When: 2013-02-24
( 80m)
No herbarium specimen

Notes: Substrate: Nothofagus spp. (probably N. pumillo, maybe N. antarcticum)

Habitat: Valley older growth gnarly Nothofagus forest, open canopy.

Description:

Upper: greenish, with brown dots (I don´t think these are pseudocyphellae, thus not a Parmelia or a Punctelia, right?), and then some brown dots that appear like perithecia, but haven´t sliced them up yet…

Lobes: narrow elongate, typical type of Parmelia lobes,

Rhizines: extensive thick black rhizines that upcurl on the margins

Here’s the confusion. Anzia anzioides = Pannoparmelia anzioides = Pannaparmelia angustata.

Yes, Anzia afromontana is also reported for southern Chile, as far south as Laguna San Rafael, but there’s no way — despite Yoshimura’s comments — that it would be mistaken for either Anzia parasitica or the two species of Pannoparmelia. Definitely not yours.

However, look at the photos of Pannoparmelia angustata in the Calvelo 1992 paper — a dead ringer for yours. And it is known from Tierra del Fuego. (Full range is Tasmania, New Zealand, South America up to Bariloche area.)

There are only two species of Pannoparmelia and both are covered in the New Zealand flora (see link with the name proposition above).

WOE

Fantastic photos of the rhizines on the Anzia… really hard to get them shown well, into position… :)

Looks like an Anzia sp.

Hate to promote my own work… but these really are the best photos on the web last I checked! :)

Anzia…? Sounds exotic

Never heard of the genus…

Yes, the rhizines look so tufted together as to look like foam… almost like a big net of black rhizines, or a matt of black fruticose lichen…

Individual rhizines? I can see the individual rhizines, but only parts of them, since they swirl back down into the net — but they are all smooth, shiny black, some forking dichotomously. I did find one individual rhizine, it was forked at the end, just a tiny little dichotomous fork in the last 0.05mm or something…

Holy s—- that’s Anzia isn’t it??

Can you describe the “rhizines” better? Are they so densely intertwined and branched as to appear almost like a “foam”? Are there any true rhizines protruding from it or from interspaces?
