Doug Waylett and the Lichens of Canada on flickr

Richard, thank you for the comparative material on the North Cascades Protoblastenia incrustans.

The Lichens of Canada series on flickr is a huge achievement, containing well over 1000 photos now, and Doug Waylett was an important source of strength in that regard. He has equally impressive collections of Alberta wildflowers on flickr, and was even beginning to upload photos of mosses, and he always took the time to be gracious to other interested individuals.

Doug’s lichen very similar to North Cascades P. incrustans

(Hello to Jason. I’ll try to post my photos on Mushroom Observer. And, don’t know if it appropriate to add here, perhaps you are not aware that on January 7 Doug Waylett passed away “suddenly and unexpectedly”.)

North American records

A quick survey of North American records of Protoblastenia on CNALH:
Protoblastenia calva : 1 record from Wells Gray Provincial Park, BC
Protoblastenia incrustans : 10 records from Newfoundland & Labrador; Brooks Range, Alaska; a few localities in BC; and 1 record from Pennsylvania
Protoblastenia rupestris : 329 records, including many from North America, but the range map does not show any records from BC or Alberta
Protoblastenia terricola : 2 records from Greenland, and 1 from southern Baja California

My concern is lack of spore data

Some Caloplaca spp. can also lack a margin (although admittedly even those species usually show at least some margin on budding apothecia). But it seems neither Doug nor you have had the opportunity to demonstrate the critical difference: are the spores septate or not? I’d be delighted to be proven wrong, but before I get all excited about this “new” genus (new to me!) I want to be sure these photos are really it. :) Stridvall has some more photos. But none show the conspicuous pits the apothecia have warn in the substrate in yours. P. rupestris, in particular_ seems to have a distinct visible chalky thallus; yours has no visible thallus at all (to my eye), just a pale stain. Bruce Ryan confirms this observation. Ah! but he does talk about P. incrustans having apothecia sunken into pits of hard limestone! There you go, now I’m almost convinced. :)

There are four species of Protoblastenia in North America, and three of them are illustrated by the Stridvall’s: Stridvall 01 Stridvall 02 Stridvall 03. Brodo remarks that Protoblastenia is “the only genus of crustose lichens with orange-yellow anthraquinone pigments in the apothecia, and 1-celled spores. Species of Protoblastenia look much like a Caloplaca without margins on the apothecia. The spores of Caloplaca are 2-celled and polarilocular.”

No way!

All my sources claimed orange apothecia meant Caloplaca. I had no idea there were other genera to consider. Well done, Chris!

[edit: Wow, the Sharnoffs’ photo in Lichens of N. Amer. looks totally different than Doug’s and yours, though. Are we sure about this?]

Caloplaca is insane

Bruce Ryan puts this in the “C. pyracea group”. Sonoran Flora puts it in C. marmorata or C. crenulatella. Looking over the C. lactea / C. crenulatella group (see, e.g., The Lichenologist 43(5), available from here) also seems to place it in either C. marmorata or C. crenulatella (depending on the shade of red/orange in the apothecia). Brodo et al. 2001 call it C. luteominea, a coastal thing, which it clearly is not (that species has conspicuous rims). Urk. We need a high-level key! If you can decide on a group, either Wetmore or Vondrák seem to have all bases covered between them… but I’m not sure which group it’s in. Except for the rims, this photo at Stridvall’s is a great match.
