Dear All,
LONG PREAMBLE:
In the course of cutting firewood I frequently see Lichens which=20
would rarely be seen in detail from the ground and bought a copy of=20
Brodo, Sharnoff & Sharnoff shortly after their Lichens of North America=20
came out.
Attempts to key these out based on morphological characters (don't=20
have the chemicals) have nearly always led to dead ends or close but not=20
quite right. And extreme frustration because the text is in alphabetical=20
order by Genera. So one can be very close and never know it because=20
members of a family are scattered throughout the 760+ pages.
Yesterday a friend found a very common lichen and asked me what it=20
was so I said Usnea but I don'r recall the species. It did not agree=20
with any Usnea in Lichens of NA, so I thumbed through all pages and=20
drew a blank.
Wondering why I had supposed it to be Usnea, I checked a small=20
Observers book of Lichens which Alison had bought in 1967 and found=20
Usnea florida at once. And a Google of Usnea florida confirmed the ID=20
without doubt.
QUESTION:
I don't have much time these days for luxury activities but would=20
like a practical and reliable key for NS lichens and experience tells me=20
that Lichens of NA is not suitable. Can anyone suggest a good source for=20
identification of NS Lichens; preferably illustrated ? [I have a vague=20
memory of having asked this question years ago but lost most e-mails on=20
my now off-line Dell when some malicious characters gained access to it.=20
And why bust a gut finding an archived copy of a 10 year old e-mail when=20
a current answer may yield something better ?]
Yt, DW, Kentville
