etymology |
Genitive plural of Latinized name, hence, "of the Wadjuk people" "Wadjuk is the name for the Nyoongar aboriginal tribal group that roamed within a 50 km radius of Perth, Western Australia. It means ‘the guardians of the link between the land and the sea’. This link is the Swan River that flows through the centre of Perth." | ||||||||||||||||||||||||

intro |
The field may contain magenta text presenting data from a type study
and/or revision of other original material cited in the protolog of the present taxon.
Macroscopic descriptions in magenta are a combination of data from the protolog and
additional observations made on the exiccata during revision of the cited original
material. The same field may also contain black text, which is data from a revision of the present taxon (including non-type material and/or material not cited in the protolog). Paragraphs of black text will be labeled if further subdivision of this text is appropriate. Olive text indicates a specimen that has not been thoroughly examined (for example, for microscopic details) and marks other places in the text where data is missing or uncertain. The following material is based directly from the protolog of the present taxon. protolog: "...the colour of spores in fresh deposit and other shades of white to cream (designated by letters A–G), are from (Royal Botanic Garden Edinburgh 1969)...." protolog: Basidiomes medium-sized to large. | ||||||||||||||||||||||||

Each spore data set is intended to comprise a set of measurements from a single specimen made by a single observer; and explanations prepared for this site talk about specimen-observer pairs associated with each data set. Combining more data into a single data set is non-optimal because it obscures observer differences (which may be valuable for instructional purposes, for example) and may obscure instances in which a single collection inadvertently contains a mixture of taxa.
