California mushrooms : the comprehensive identification guide by Dennis E Desjardin( Book )

5 editions published between 2015 and 2016 in English and held by 94 WorldCat member libraries worldwide

"California is one of the most ecologically rich and diverse regions of North America, and home to hundreds of species of mushrooms. In California Mushrooms, mycologist experts Dennis Desjardin, Michael Wood, and Fred Stevens provide over 1100 species profiles, including comprehensive descriptions and spectacular photographs of 650 species. Each profile includes information on macro- and micromorphology, habitat, edibility, and comparisons with closely related species and potential look-alikes. Although the focus of the book is on mushrooms of California, over 90% of the species treated occur elsewhere, making the book useful throughout western North America. California Mushrooms also provides information on when and where to find mushrooms; guidelines on how to collect and identify mushrroms; keyes to species; and overviews of nomenclature and taxonomy, morphology and phylogeny, fungal ecology, biology of mushrooms, and mushroom toxins. This complete reference covers everything necessary for the mushroom hunter to acurately identify over 650 species"--Publisher's description

Considerations and consequences of allowing DNA sequence data as types of fungal taxa by Juan Carlos Zamora( )

1 edition published in 2018 in English and held by 1 WorldCat member library worldwide

Nomenclatural type definitions are one of the most important concepts in biological nomenclature. Being physical objects that can be re-studied by other researchers, types permanently link taxonomy (an artificial agreement to classify biological diversity) with nomenclature (an artificial agreement to name biological diversity). Two proposals to amend the International Code of Nomenclature for algae, fungi, and plants (ICN), allowing DNA sequences alone (of any region and extent) to serve as types of taxon names for voucherless fungi (mainly putative taxa from environmental DNA sequences), have been submitted to be voted on at the 11th International Mycological Congress (Puerto Rico, July 2018). We consider various genetic processes affecting the distribution of alleles among taxa and find that alleles may not consistently and uniquely represent the species within which they are contained. Should the proposals be accepted, the meaning of nomenclatural types would change in a fundamental way from physical objects as sources of data to the data themselves. Such changes are conducive to irreproducible science, the potential typification on artefactual data, and massive creation of names with low information content, ultimately causing nomenclatural instability and unnecessary work for future researchers that would stall future explorations of fungal diversity. We conclude that the acceptance of DNA sequences alone as types of names of taxa, under the terms used in the current proposals, is unnecessary and would not solve the problem of naming putative taxa known only from DNA sequences in a scientifically defensible way. As an alternative, we highlight the use of formulas for naming putative taxa (candidate taxa) that do not require any modification of the ICN
