The North American Species of Pholiota

Curator, The Rijksherbarium, Leiden; Dr. Meinhard Moser, Bodenbiologisches Institut, Imst, Austria; Dr. G. Taylor, Director, Royal
Botanic Gardens, Kew; Dr. R. Watling, Royal Botanic Garden, Edinburgh; Dr. H. E. Bigelow, University of Massachusetts, Amherst; Dr.
Kenton L. Chambers, Oregon State University, Corvallis; Dr. James
Kimbrough, Curator, The University of Florida; Dr. Patricio Ponce de
Leon, Curator, The Chicago Natural History Museum, Chicago; Dr.
Richard Korf, Curator, Cornell University, Department of Plant Pathology Herbarium; Dr. I. MacKenzie Lamb, The Farlow Herbarium, Harvard University; Dr. Clark T. Rogerson, Herbarium, The New York
Botanical Garden, New York City; and Mr. Stanley Jay Smith, The
Herbarium, New York State Museum, Albany. We also acknowledge the
generosity of Dr. H. E. Bigelow, who made his photographs of Pholiota
species available to us; and finally, our thanks to more than a score of
devoted and zealous amateur mushroom hunters for the many interesting
and new species they have communicated to us for study.
Four courtesies extended in aid of field work we wish to acknowledge
the wholehearted cooperation of the National Park service for the opportunity to collect in the Great Smoky Mts. National Park, Mt. Rainier
National Park, the Olympic National Park and in the Rocky Mountains
National Park. These areas play a most important role in preserving
large tracts of our native forests for posterity and of course this means
the preservation of all the elements of the forest biota. We wish also to
acknowledge similar courtesies extended by the staff of the United States
Forest Service, United States Department of Agriculture, from the forest
superintendants as well as the rangers and other field personnel. Their
help has been of inestimable value in locating quickly the type of site
desired for a particular problem. Their patience with the working as well
as recreating public is a model for all to follow. Beyond this, however, we
wish to particularly acknowledge the facilities placed at the disposal of
Smith and his party at the Priest River Experimental Forest, a unit of the
Intermountain Forest and Range Experiment Station, Mr. Joseph Pechanec, Director. The location is ideal for the study of Pholiota, being as
it is in the center of the Idaho white pine belt.
The University of Michigan Biological Station, Dr. A. H. Stockard,
Director, was our most important central Great Lakes base of operations,
but we also wish to acknowledge the opportunity granted Smith by the
Huron Mountains Club and its Wildlife Foundation for the privilege of
collecting in the virgin forests now dedicated by the Club as a natural
area.
