Today I was reading about taxonomy and lichens. I found something that I think is very fitting:
"(...) as stated by Santesson (1954), 'in no other group of plants is the taxonomic work carried out more carelessly than in lichenology'."
Honegger R (1983) The Ascus Apex in Lichenized Fungi IV. Baeomyces and Icmadophila in Comparison with Cladonia (Lecanorales) and the Non-Lichenized Leotia (Helotiales), Lichenologist 14: 205-217
I think the modern lichenologist are no longer like that, tho.
