Abstract
The nutritional modes of genera in Hygrophoraceae (Basidiomycota: Agaricales), apart from the ectomycorrhizal Hygrophorus and lichen-forming taxa, are uncertain. New δ15N and δ13C values were obtained from 15 taxa under Hygrophoraceae collected in central Massachusetts and combined with isotopic data sets from five prior studies including a further 12 species using a data standardization method to allow cross-site comparison. Based upon these data, we inferred the probable nutritional modes for species of Hygrophorus, Hygrocybe, Humidicutis, Cuphophyllus, and Gliophorus. A phylogeny of Hygrophoraceae was constructed by maximum likelihood analysis of nuclear ribosomal 28S and 5.8S sequences and standardized δ15N and δ13C values were used for parsimony optimization on this phylogeny. Our results support biotrophy in Hygrocybe, Humidicutis, Cuphophyllus, and Gliophorus quantitatively unlike that in more than 450 other fungal taxa sampled in the present and prior studies. Parsimony optimization of stable isotope data indicates moderate conservation of nutritional strategies in Hygrophoraceae and suggests a single switch to a predominantly ectomycorrhizal lifestyle in the lineage leading to Hygrophorus. We conclude that Hygrophoraceae of previously unknown nutritional status are unlikely to be saprotrophs and are probably in symbiosis with understory plants.
