More about this plant
Funaria hygrometrica, the bonfire moss or common cord-moss, is a type of water moss which grows on shady, moist soil. It can also be found on moist walls and the crevices of rocks and places where recent fires have taken place. It has been reported to grow in Niagara Cave, an artificially illuminated cave devoid of natural light. Under such conditions, its growth form changes so that the internodes lengthen and the leaves become longer and narrower. Wikipedia →

How we know this (1) Methods & honest limits
We take the plant’s U.S. county range and look up each county’s long-term climate, then summarise: native rainfall = the median annual rainfall across its counties; heat tolerance = the warm end (90th percentile) of average temperature across its range (mirroring how our cold-hardiness floor uses an extreme). Counties + medians blunt the roadside/observer bias that makes point-level climate unreliable. Needs at least five placeable counties.
Honest limits: A realized, sampling-biased niche (where it has been recorded, not its physiological optimum), and county climate is coarse — large Western counties span deserts and mountains. Derived guide, never a measured fact.
