# Talk:Physcia caesia

Move medullary reaction (potassium yellow) from ecology to description. Mention other spot test reagant reactions/nonreactions? Apparently it's P+ yellow, C-, KC-. Do Brodo & Sharnoff mention non-reactions?
Fungus GAs often have a "Similar species" section. Create such a section? Could include P. dubia as mentioned in Mosberg & Hansen and P. aipolia, probably others.
"Ecology" section needs reorganization; conceptually I think you have 4-5 topics with info; global distribution, substrate, habitat/associated species/ecology, and tolerances/chemical physiology. Distribution and substrate info is especially mixed together. Fungi usually have a "Distribution and habitat" section; consider splitting "Ecology" into two (or more) sections.
Grows in Europe, North America, cool temperate southern hemisphere. And also Antarctica, which I wouldn't call "cool temperate". What cool temperate southern continents have it? Is really not found in Asia as currently implied?
Rarely grows on bark/predominant lichen on junipers. These two facts seem contradictory and need better integration (I suppose it could be rare on bark, but when it's on bark, it's often juniper bark).
List subspecies in taxobox
Starting a paragraph with an abbreviated binomial (P. caesia) looks really ugly to me. Style guides often recommend against starting sentences (not just paragraphs) with an abbreviation. However, I see it a lot in FAs/GAs for organisms. I don't know if that practice is coming from the proposed MOS:ORGANISMS, but after some discussion, the guidance there was recently changed to use the unabbreviated form at least in the first instance per section.Plantdrew (talk) 02:05, 4 June 2017 (UTC)

Thanks Chiswick Chap! I'll tackle your suggestions... MeegsC (talk) 16:50, 28 August 2017 (UTC)


### General comments
This is a well-written article which plainly covers the topic, supported by plenty of reliable academic sources.


### Specific comments
I guess a brief nod towards its tolerance of air pollution (does it occur in cities?) would be useful.
Please put the bryophyte species Tortula ruralis, Orthotrichum anomalum, Grimmia pulvinata, Schistidium apocarpum into italics. done
Does balsitic mean basaltic, or something else? A wikilink might be useful. Typo; fixed.  done
epiphtyically -> epiphytically  done
It would be nice to know what (genera) the other lichens are in the photos. Not a requirement.
Soredia or soralia? Or are these exact synonyms?
These are different things. Soredia are tiny bits of fungi wrapped around a photobiont; located on the upper surface of the thallus, they can break off to form new colonies. Soredia can either be scattered diffusely across the thallus (some species) or clumped in discrete areas called soralia (like P. caesia's bluish mounds). I'll add something to the soredium article explaining this.
It would be very nice to have a diagrammatic cross-section to show thallus, rhizines, apothecia, soredia. Not a requirement.
Cited books should be in alphabetical order of surname. Fixed one out of order. done
@MeegsC - we can almost close this out, but I think we need a brief word on soredia/soralia here just to avoid confusion, whatever the other article may one day come to say. A reply to the air pollution item would also be helpful. Chiswick Chap (talk) 08:59, 8 September 2017 (UTC)
@Chiswick Chap: — Sorry! Will respond ASAP. On tour right now, and won't be home until next week (13/9). Will finish up then! MeegsC (talk) 17:09, 8 September 2017 (UTC)

@Chiswick Chap: - can you please check my clarification on the soralia? Is it clear enough now? I'll see if there's anything else on pollution tolerance beyond what I've already put it. MeegsC (talk) 21:34, 18 September 2017 (UTC)
That's fine, many thanks. I think the article will pass muster at GA now. Chiswick Chap (talk) 21:48, 18 September 2017 (UTC)
Thanks so much for the review — and for being patient while I was in the field! MeegsC (talk) 22:22, 18 September 2017 (UTC)
