The following text may make multiple use of each entry field.
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
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 habit and pileus pigmentation of this species are
strikingly similar to that of the North American
penetratrix. Based on this observation,
we projected that the two species might be
They are similar in one way—the nrITS 5' motif for this species is of the form
that distinguishes the provisonal subsection
We estimate that about 30% of the published and
