Fungus name aeminium ludgeri root words:
Aeminium was the Roman name for the town before Coimbra. I suppose this is a timestamp as well.
Ludgeri appears to be a style of church or religious architecture of some sort of the period. Since the fungus is unique to the limestone quarry from which came the building material for multiple buildings and constructions of a similiar nature perhaps the fungus was found there also and the name is a grouping of some sort?
Personally, when I first read the name of the fungus I came away with a phonetic laugh having something to do with luddites saying amen. Had to look it up on google then of course. I found out about the Roman town name, but the root Lud is sort of a mocking or entertaining description as in
combined with geri which is basically old as in geriatric. I often wonder about how these things get named. Perhaps a little concern over why I feel compelled to look this stuff up is in order as well.
