Re: Lowest pinnae length as ID clincher

ello Larry,
    You are most welcome.  It always helps wehn you have an idea where a

in the improbables.  It does make identifying rogue sporlings that appear in
spores from spore exchanges an interesting challenge.  I deal with many such
species in many genera continually.
