we´re going in deep! And its just the beginning!

But, what´s super cool, is that we´re brainstorming having our lichen biodiversity plots within the plant biodiversity plots — and for species that we don´t know, which will be nearly everything I think since we don´t have the gear to really ID nor the right keys (de la Torre has no key… ), then we´ll give them their own unique name and description of macro-features. One way or another… :)

Teloschistes, too!

There must at occasionally be fog or mist. Doesn’t matter how dry and poor the grasses necessarily. Look at all the weird hair lichens on cacti in northern Chile! Good stuff.

Alectoria jubata is a trashcan name, might even refer to Bryoria, actually. Can’t find A. patagonica. Lots of Usnea in that list I don’t know anything about. Also don’t have a clue about Coelopogon! We’re in trouble, I think. :)

According to Oscar Pérex de la Torre´s book on lichens of the Chubut Province, the following Alectoria species are present here (I didn´t check for central cord, so its a possibility, but I´m leaning towards Usnea still, but anyeays, here´s the potential Alectoria here:
A. jubata
A. patagonica

Yeah, isn´t that odd…

I didn´t expect to find Usnea out here at all (it seems like Usnea right? Maybe Coelopogon? Wild…).

Maybe I should expect Usnea here, there´s some Usnea in the arid Channelled Scablands and over on the E. side of the Cascades and in the humid zone along the Columbia River… and it must be humid here just 100m away from the seashore, but here there´s hardly even any grass, its totally shrubby and bare ground… and voila, bam, there on a shrub, a couple thalli – along with a Teloschistes chrysopthalmus and what seemed to be a orange Lecanora like or maybe Xanthoria like dudette, maybe, either way, an orange thalline apotheciated crust. And then a really neat gray soil crust below the spinuose shrub. But its so odd, or maybe it makes sense, that everywhere else I´ve looked, including in the bush along the road from Puerto Madryn to Punto Loma (our class road bikes the 18km there so I could hop off and take a gander whenever I liked, just amazing!) but yes, no Usnea since that shrub yesterday.

But… get this… found was a Líuenes de la Provincia del Chubut book at the Museo Pleontológico Egidío Refuglio in Trelew… my life just became more euphoric… :) No key, but lots of microscopic photos of ascomata types I´ve never seen before… :)

Aha! So there are epiphytes out there!

How hard do you have to look to find anything?
