Crusts, such as lichens that grow on a solid substrate, are a dynamic mixture between a V0- and a V1-morph, where the inner part acts as V0-morph, and the outer annulus as V1-morph.The mixture is called dynamic because the weight coefficients of the contributions of the V0- and V1-morph terms in the shape correction function change during growth.
Crusts, such as lichens on a solid substrate, are a transitional mix between two morphological forms, V0 and V1, where the inner part embodies V0 characteristics and the outer ring exhibits V1 traits. This dynamic mixture is characterized by changes in the weight coefficients of V0 and V1 contributions during growth.
