Puccinia umbilici is a fungal rust on Navelwort - Umbilicus rupestris. These species names show that the latin version can be quite useful: the rust is explicitly associated with the plant by name.
And in some cases there is simply no English name. This is Lepraria incana agg. - a lichen that grows on unstable earth and is propagated when the soil moves. The 'agg' means that there are a number of very similar species that are 'lumped' into a single aggregate.

I know there are at least 4 species in this image, although I can only see 3. The wood is Gorse (1). The orange fungus is Tremella mesenterica(2), which doesn't live on Gorse, but is parasitic on another fungus Peniophora incarnata (not visible, 3). And there is a green alga (4) of some sort.
