Spatial pattern of sporophores of three species of fungi around a tree.
A multitype spatial point pattern (an object of class
with factor-valued marks indicating the species).
Spatial coordinates are given in centimetres.
Levels of the species variable are
"L pubescens" and
Ford, Mason and Pelham (1980) studied the spatial locations of sporophores of three species of mycorrhizal fungi distributed around a young birch tree in agricultural soil. The dataset given here is the spatial pattern in the fifth year after the tree was planted. The species are Laccaria laccata, Lactarius pubescens and Hebloma spp.
