| intro |
The following text may make multiple use of each
entry 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 is based molecular research of Dr. Linas Kudzma and other original research of R. E. Tulloss and C. Rodríguez Caycedo. | ||||||||||||||||||||||||||||
| pileus | 45 - 55 m wide,dark gray-brown (ca. 6E3), elsewhere slightly virgate and ca. 6D3 (grayish brown), lacking an umbo or slightly depressed over disc, tacky, viscid when moist, entirely subshiny or shiny over disc; context off-white, may become grayish with age except over stipe, in age becoming pale brown in invertebrate tunnels, without any pileipellis coloring "bleeding" into context, 1.5 - 3 mm thick over stipe, thinning evenly for two-thirds of radius, the membranous to margin; margin nonappendiculate, striate (0.3 - 0.45R); universal veil absent or as small patches or large warts and then smooth and membranous and whitish and becoming ochraceous with age. | ||||||||||||||||||||||||||||
| lamellae | free to very narrowly adnate, with ephemeral decurrent line on stipe, subcrowded to crowded, sordid cream in mass, whitish to pale yellow-cream in side view, with edge uncurved and sometimes becoming brownish with age, 4.5 - 5 mm broad, broadest at 75% of length from stipe; lamellulae truncate to subtruncate, plentiful, unevenly distributed, of diverse lengths. | ||||||||||||||||||||||||||||
| stipe | 65 - 110 × 5 - 8 mm, off-white, browning when handled in age, narrowing upward, flaring at apex, very finely pulverulent above, finely longitudinally striatulate for most of length, sometimes with upward-pointing fibrillose scales in age; context stuffed with loosely packed longitudinally arranged fibrils and becoming hollow below with age, pale cream to whitish, staining or bruising as ochraceous spots in age, with invertebrate tunnels concolorous in young material and concolorous to ochraceous to fulvous to deep brick red (in stipe base) with age, with central cylinder 2 - 3.5 mm wide; exannulate; universal veil sacccate, membranous, smooth whitish, firm, persistent, less than 1 mm thick, with length from base of stem to highest point on limb up to 32 mm, with width up to 18 mm, adnate to stipe in bottom (up to) 12.5 - 15 mm; limbus internus unusually long despite evidence of deterioration in the single specimen on which notes exist, not paper thin. | ||||||||||||||||||||||||||||

Spore data sets and their composite
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.
