| intro |
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 on molecular studies
of Dr. K. W. Hughes and other original research
of R. E. Tulloss.
This species was formerly called "sp-amerirubescens05" on
these pages. |

| discussion |
Both of the specimens from which spores were measured
were over mature when
dried. Moreover, RET 548-10 did not dry well.
In consequence, the sample of spore data is not only
small, but probably understates the dimensions of the
spores. Possibly, values of Q computed from the
spores are lower than they will be when data is
available from spore prints or gills of material that
is mature, but not over-mature.
The entity was formerly called "sp-amerirubescens05" on
these pages. |
