An unusual growth form of Cladonia furcata: The trampling-resistant primary thallus colonizing a paved pathway [PDF]
Lichens are well known to be susceptible to damage by trampling. Fruticose species, with their highly branched structure, are particularly sensitive and Bayfield et al. (1981) described substantial damage to Cladonia uncialis, C.
