When I see this colour in a local coral fungus I think Clavulina, simply because usually whenever I’ve studied any specimen such as this, that is the genus I find. But remember that my calling this a Clavulina is based on probability, not certainty. A creamy/brownish/greyish Clavulina (usually with wrinkled stems) is reasonably common here (and perhaps more than one such species is present), often growing in good-sized colonies, but only a few centimetres tall and easily overlooked in leaf/twig litter.
As a matter of interest, it was growing at the point of the overflow of one our water tanks into a swale we built. I think we still had rain in those days...
