There suddenly seems to be a glut of observations featuring lichens, but with no attempt at identification to species and concern only whether the lichen is crustose, foliose or fruticose (and often getting these wrong and misunderstanding the foliose/fruticose distinction - many foliose species have aerial branches!).
I have been providing identifications where possible, though the photographs are often of low standard, but I am starting to wonder about this whole phenomenon.
I note that all these posts are coming from Open University students. Has someone set them an exercise to go out and take low resolution, out of focus photographs, post them as observations with IDs only to "crustose, foliose, fruticose" and get mugs like me to tell them if they are right? If so, I have plenty of my own coursework and exam papers to mark.
Anyone trying to get to know the lichens of their own area will usually meet a lot of very poorly developed urban specimens of genera that are difficult even with good material. I for one am happy to help, when/if I can (displacement activity to put off my own marking), but I have decided to ignore posts that seem only interested in the flawed and arbitrary classification of convenience, applied by us humans, to the large and more or less continuous diversity of lichen structure.
And what about leprose, squamulose, etc.?
