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. | ||||||||||||||||

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. | ||||||||||||||||
