SUMMARY Thalli of four saxicolous lichens on slate rock fragments were transplanted from rock surfaces to horizontal boards and then to south‐east‐facing and north‐west‐facing rock surfaces. The radial growth rate of Physcia orbicularis and Parmelia conspersa thalli declined after transplantation to north‐west‐facing rock surfaces and was unchanged after transplantation to south‐east‐facing rock surfaces compared with growth rate on the boards. The radial growth rate of P. glabratula ssp. fuliginosa thalli declined after transplantation to south‐east‐facing rock surfaces and was unchanged after transplantation to north‐west‐facing rock surfaces compared with growth rate on the boards. The radial growth rate of P. saxatilis thalli was similar on the horizontal boards, south‐east‐facing and north‐west‐facing rock surfaces. Those results are discussed in relation to the aspect distributions of the four lichens in South Gwynedd, Wales.
