Description

It was first described in 1753 by Carl Linnaeus with the name Lichen saxatilis. Erik Acharius transferred it to Parmelia in 1803.[2] The lichen has a greenish-gray to bluish-gray thallus that can turn brown in exposed locations. It typically grows on rock, although it is sometimes found on bark or wood. Parmelia saxatilis is used to make dyes with deep red-brown and rusty-orange colors.[3] Known as "crotal" in Scotland, it was used to dye traditional cloths including Harris tweed.[4][5] A somewhat similar species with a cosmopolitan distribution is Parmelia sulcata, which generally grows on trees.

gollark: The somewhat-naive way would be a bit slow if you have a *lot* of them, but there are definitely algorithms for doing this quicker somehow.
gollark: I'm pretty sure that if you have a list of the DNA/RNA of all known viruses you can probably filter out close matches to them fairly easily.
gollark: Really? I assumed you could just check Levenshtein distance from known viruses or something.
gollark: Can you somehow just sequence whatever DNA/RNA gets caught *automatically*?
gollark: YOU need an arbitrarily large quantity of bees.
