Abstract

Calostoma cinnabarinum belongs to the suborder Sclerodermatineae (Boletales), an ectomycorrhizal group of basidiomycetes, but the genus Calostoma has been described as saprotrophic. This study combines isotopic, molecular and morphological techniques to determine the ecology of C. cinnabarinum. To determine C. cinnabarinum's mode of nutrition, d13C and d15N measurements were compared among co-occuring Calostoma cinnabarinum, ectomycorrhizal fungi, saprotrophic fungi and EcM host plants. Ectomycorrhizal root tips were extracted from soil cores collected beneath C. cinnabarinum fruit bodies. nrITS sequences were obtained from root tips and screened against C. cinnabarinum nrITS sequence to determine if they matched. Root tips colonized by C. cinnabarinum were also described morphologically. Calostoma cinnabarinum resembled EcM fungi but not saprotrophic fungi isotopically. Ectomycorrhizal root tips have nrITS sequences that match C. cinnabarinum fruiting bodies. Several morphological characters are shared between fruiting bodies and EcM root tips of C. cinnabarinum. Results of isotopic, molecular and morphological analyses indicate that Calostoma cinnabarinum is ectomycorrhizal. Molecular analysis and observations of plant associations suggest Calostoma forms ectomycorrhizae with the Fagales.
