| intro |
There may be multiple uses of each data 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
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 not directly from the protolog
of the present taxon and not cited as the work
of another researcher is based on molecular studies
by Drs. Joszef Geml, Linas Kudzma, Karen W. Hughes,
and Danny Haelewaters; other original
research is by R. E. Tulloss. |
| pileus |
52 mm wide, light yellowish to light orangish tan
(2-3A3), paler toward magin, slightly darker over
disc, no color change observed, convex;
context 5 mm thick above stipe,
whitish-yellowish under pileipellis, sometimes
separated from stipe context by watery line, not
changing when cut or bruised;
margin tuberculate-striate (0.25-0.3R), not
appendiculate, incurved; universal veil often
absent. |
| lamellae |
free to narrowly adnate with minute decurrent line on
stipe (10× lens), close, white in mass and in
side view
and unchanging when cut or bruised, 5 - 6 mm broad;
lamellulae truncate or truncate-excavate, with
tooth at pileus context. |
| stipe |
61 × 5 mm, whitish, browning from handling;
bulb subglobose, 5 ×
5.5 mm, whitish, flexuous, narrowing upward, flaring
at apex, longitudinally striatulate;
context stuffed firmly,
white, color changing not
observed, with central cylinder 1.5 mm wide, with
larval tunnels concolorous or very pale tan or buff;
partial veil
whitish, superior, funnel-shaped at first, rather
narrow, often tearing away from stipe or shredding
due to pileus expansion; universal veil
white, cothurnate or as flimsy color encircling
top of bulb
ca. 1 - 2 mm from juncture of stipe and bulb. |
| odor/taste |
Odor fungoid; taste not recorded. |
macrochemical
tests |
L-tyrosine - rapidly positive on pileus surface,
positive on pileus context; rapdily positive on
surface and context of stipe; positive more slowly on
lamellae. |
| lamella edge tissue |
sterile. |

| discussion |
RET 564-5 is immature and much of the hymenium was
sterile when it was dried. The spores do not
seem to be fully inflated and are distinctly narrower
than the spores of mature material such as measured
for (e.g.) RET 483-10. Thus we expect the
average Q value (Q')
currently given above is too high. As more
material is revised, we think Q' may well
descend below 1.30.
Matching nrITS sequences from GenBank and unpublished sources
indicate that the same
species may be found in Massachusetts (Boston Harbor
Island project, at least four collections) and in
Florida (GenBank MH212133).
Some of the annulate collections previoiusly assigned
to A. sp-34 on this site have been
demonstrated phylogenetically to belong in the present
species. |
