Dr. Charles Drechsler
(1892-1986) published 185 scientific papers during his career of over 45
years
with the U.S. Department of Agriculture. One-hundred forty seven of
these papers were full-length, major
publications.
The reprints that are available include
an excellent monograph on graminicolous helminthosporia
published in 1923. For this work, S. Ito later renamed one group
of the helminths, Drechslera, in honor of Dr. Drechsler. Other
classical works include descriptions of 21 new species of Pythium,
as well as Phytophtora megasperma, and several species of Aphanomyces,
notably A. euteiches and A. cochioides.
His work on the oomycetes led to extensive and classical studies on
parasitism and predation of the soil microflora and microfauna by soil
fungi. Species are described that parasitize oospores and
and mycelium of the oomycetes, eggs and adults of nematodes, and many
soil amoebae and rhizopods. Over 60 major publications described
predation of nematodes, the capturing of amoebae, and the parasitism of
testaceous rhizopods. Many publications deal with newly described
species of Basidiobolus and Conidiobolus, belonging to the
Entomophthoraceae. Most of Dr. Drechsler's publications are
accompanied by excellent line drawings. These drawings represent
the work of a precise and critical observer and an artist at
illustration. The collection of reprints represents a lifelong
career of one of the world's eminent mycologists and plant pathologists. |
