intro | At present, please see the technical tab of this page for the data being collected concerning A. justicei. |
odor/taste | This species has no appreciable odor, and its taste has not been recorded. |
spores | The spores of this species measure (7.6-) 9.6 - 11.4 (-12.3) × (7.0-) 8.6 - 10.3 (-11.0) μm and are inamyloid and subglobose to broadly ellipsoid. Clamps are absent from bases of basidia. |
discussion | This species is presently known from three counties in Missouri and one in New Jersey. A somewhat similarly pigmented taxon or group of taxa (see A. sp-T06) in eastern Texas is quite distinct from the present species.—R. E. Tulloss and L. V. Kudzma |

intro |
The following text may make multiple use 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/or molecular data) and marks other places in the text where data is missing or uncertain. The following material is based on the notes and photographs of the collectors, the molecular research of Dr. L. V. Kudzma, and other original research of R. E. Tulloss. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

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.
