Dr.  William  A.  Weber, Professor Emeritus at the University of
Colorado at Boulder, has been awarded the Edgar T. Wherry  Award
by the North American Rock Garden Society.

As  quoted  from  "A  History  of the North American Rock Garden
Society" the Edgar T. Wherry Award is "...given to a person  who
has  made  an  outstanding  contribution in the dissemination of
botanical and/or horticultural knowledge about  native  American
plants....Generally  the  award  recognizes  a body of work or a
lifetime of literary effort rather than a single work."

[Pteridologist and geologist Dr  Edgar  T.  Wherry  (1885--1982)
served  as  president  of  the  American  Fern  Society, and the
Mineralogical Society of  America.  When  he  was  Professor  of
Botany  at the University of Pennsylvania, Wherry was the editor
of the Bulletin of the American  Rock  Garden  Society  and  en-
couraged appreciation for native plants among gardeners.]

The award announcement (Rock Garden Quarterly 56: 298-299) cites
Dr.  Weber's  "monumental  contributions to botanical knowledge,
and awareness locally, nationally, and internationally."

BEN readers know Dr. Weber from his many  stimulating  contribu-
tions  (e.g., "Vernacular names: why, oh why?" - BEN # 109), and
BEN  celebrated  Dr. Weber's  80th  birthday  in  special issues 
# 207, 208 and 209, just a year ago.

In  recent  years,  Calicioid,  or  "stubble"  lichens have been
attracting attention as  surpassing  bioindicators  of  relative
forest  age.  Resembling  diminutive  straightpins  (or,  if you
prefer, lilliputian stubble), most stubble lichens are  at  home
on  the  sheltered  undersides  of  leaning  trees. Some species
prefer conifers, while  others  inhabit  the  wood  or  bark  of
deciduous  trees.  At  north  temperate  and  boreal  latitudes,
stubble lichens can be found  pretty  well  wherever  there  are
trees. But only in humid inland forests do they really come into
their  own.  The  richest  (and  presumably  oldest!)  oldgrowth
forests yield as many as thirty different species. By  contrast,
mature forests less than about 150 years old hardly support half
this  number;  while species numbers in young plantation forests
seldom rise above about five or six.

The down side of using stubble lichens as ecological  indicators
is  that  they  themselves  are  notoriously difficult to get to
know. This is partly owing  to  their  small  size  and  extreme
morphological variability, but mostly it reflects a general lack
of entry-level treatments to these species. Earlier this year, I
attempted to rectify this situation for western North America by
preparing  "user friendly" keys to all 71 stubble lichen species
known to occur in British Columbia [see Part 2  of  "Lichens  of
British Columbia: illustrated keys", available from Crown Publi-
cations, Victoria - cf. BEN # 231].

As  coincidence  would have it, a second quite usable account of
the stubble lichens appeared almost simultaneously with my  own!
That  account,  however,  has  the  advantage  of  having  being
prepared by the undisputed dean of calicioid studies  worldwide,
Dr. Leif Tibell, of Uppsala, Sweden. Doubling as Volume 1 in the
"Nordic  Lichen  Flora" series, this 74 page treatise represents
the first truly comprehensive treatment of stubble  lichens  yet
to  have  appeared  in  Europe. Included here are keys, detailed
descriptions, chemical notes,  habitat  summaries,  nordic  dis-
tributional  maps,  and colour photographs. For most genera, all
species occurring in British Columbia are treated in  detail  in
Tibell's  book  -- the only exceptions being Stenocybe major and
several species in the genus Chaenothecopsis.

Unfortunately for the beginner, the terminology in Tibell's book
is unstintingly technical, while the book itself lacks  anything
resembling  a glossary of terms. Yet these "deficiencies" can be
largely overcome by using the Nordic book as a companion  volume
to  the British Columbia treatment, in which all technical words
are carefully defined, and many are  illustrated.  By  the  same
token, those who use the British Columbia treatment will benefit
greatly  from  the descriptions and photographs presented in the
Nordic book. From this it can perhaps be  concluded  that  these
books  work well together. They are, so to speak, the fungal and
the algal partners of a single learning experience.

In my study of European populations of  Conyza  canadensis  (L.)
Cronq.,  I  would  like to compare those with the native popula-
tions in North America. I would greatly appreciate seed  samples
from throughout its native, North American range. - Many thanks!
