Very similar to T. caespitum in appearance and in many aspects of biology (q.v.). Forms dense populations of populous colonies very locally in favoured localities. Likely to be locally dominant and important ecologically, but it is quite unobtrusive and easily overlooked (in contrast to T. caespitum). British records only recognised as being distinct from T. caespitum in 2025. Previously T. alpestre was mainly known as a high mountain species in Central Europe (‘alpestre’ being Latin for ‘alpine’).
