| 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 derived from collectors
information and photographs, molecular research of
Dr. Santiago Sanchez-Ramírez, and other
original research of R. E. Tulloss. |
| odor/taste |

pseudoparenchymatous (cellular); inflated cells
globose (e.g., 9.5 × 9.5 μm) to elongate

layers. |
| basidia |
32 - 50 × 8.5 - 10.0 μm, 4-sterigmate, with

| discussion |
The material examined to date was dried prior to
spore development or prior to maturity of most of the
hymenium. Probably as a consequence, the distribution
of measured spore lengths lacks a high value tail.
In turn this implies that the average length and (very
probably) the average Q values presented above are lower
than they would be if data had been take from mature
material or a spore sprint from such material. |
