The Hydnaceae, or spine fungi, is one of the smaller families of the Agaricales, or, as they were known to the older mycologists, the Hymenomycetes, numbering as it does only about five hundred species. Of these some are widely dispersed and rather common while others are quite sporadic or even local in their occurrence. Only a few members of the family are common in our state, yet their number is more considerable than the published accounts would indicate, as but four species appear to have been recorded from Iowa.
