Talk:Physcia caesia

An informal review

 * 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.
