Excerpt from European Fungus Flora: Agaricaceae It conveys the idea that species are much more sharply defined than proves to be the case, when the entire Fungus Flora of Europe is included. In all large genera common to European countries, the continental species can be sandwiched between British species. Even in large genera there are as a rule not more than eight or ten primary differentiating specific characters present, and it is the constant correla tion of two or three of those primary characters that constitute a species, as understood at the present day. If two British species are characterised respectively by the marks 1, 2, and 3, 4, then we find that two continental species belonging to the same genus will be indicated by the characters 1, 3, and 2, 4, respectively. Primary specific characters should include only those features that are constant, and not materially modified by geographical or exceptional local conditions as to environment, etc., and such alone should constitute a specific diagnosis. Trivial or local characteristics should follow the essential diagnosis as a rider. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books. Find more at ...
