Hello iNat community,
recently I have taken an interest in the non-axenic cultivation of synanthropic lichens. While I have located a number of interesting papers on Researchgate, I have been unable to locate any outdoor specimens except for several yellow/orange dot clusters (I imagine these are an assorted mix of Caloplaca and Candelariella) in areas severely contaminated with hazardous vertebrate droppings. Furthermore, an Observations search in iNat for lichens of Los Angeles County (my area) did not appear to be effective, despite many listed synanthropic spp. apparently having plenty of suitable nontoxic substrate to potentially colonize in local gardens. Any tips or advice on this phenomenon? It appears that weedy dessication-tolerant mosses have claimed most of the niches for them.
Thanks in advance
