Peltigera leucophlebia

Peltigera leucophlebia is a lichenized fungus in the family Peltigeraceae. It is commonly called ruffled freckled pelt. This and other species in the genus contain a green algae in the genus Coccomyxa and also cyanobacteria in the genus Nostoc as symbionts.[1]

The thallus of this lichen is gray or brown, but when it is wet, the bright green algae are clearly visible. The lower surface of the thallus is white.

This species is found in North America, Asia, and Europe.[2] In North America, it is found in most of Alaska and Canada, the Great Lakes region, New England, the Rocky Mountains, and the Pacific coast.[3]

gollark: ``` [...] MIPS is short for Millions of Instructions Per Second. It is a measure for the computation speed of a processor. Like most such measures, it is more often abused than used properly (it is very difficult to justly compare MIPS for different kinds of computers). BogoMips are Linus's own invention. The linux kernel version 0.99.11 (dated 11 July 1993) needed a timing loop (the time is too short and/or needs to be too exact for a non-busy-loop method of waiting), which must be calibrated to the processor speed of the machine. Hence, the kernel measures at boot time how fast a certain kind of busy loop runs on a computer. "Bogo" comes from "bogus", i.e, something which is a fake. Hence, the BogoMips value gives some indication of the processor speed, but it is way too unscientific to be called anything but BogoMips. The reasons (there are two) it is printed during boot-up is that a) it is slightly useful for debugging and for checking that the computer[’]s caches and turbo button work, and b) Linus loves to chuckle when he sees confused people on the news. [...]```I was wondering what BogoMIPS was, and wikipedia had this.

gollark: I think it's a server thing.
gollark: My slightly newer SomethingOrOther 5000 does too.
