| 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 based on original research of R. E. Tulloss. |
| pileus |
57 mm wide, at first pale brown with darker brown over disc/umbo and inner ends of marginal striations, darkening and taking on yellowish gray tint with age, concave with pronounced central umbo, tacky; context white, unchanging, 5 mm thick over stipe, thinning evenly for 0.75R then as membrane to margin; margin striate (0.35–0.4R), nonappendiculate; universal veil absent. |
| lamellae |
free, with short decurrent line on stipe apex, subcrowded to crowded, pale cream in mass, off-white in side view, unchanging, 4.5 mm broad, with one fork observed; lamellulae truncate, unevenly distributed, of diverse lengths, common. |
| stipe |
200 × 8 mm, off-white, becoming pale orange-brown from handling, narrowing upward, flaring just at apex, with up to 133 mm inserted in substrate, in bottom two-thirds having gray or off-white fibrils in "flame" (aka "snakeskin" or "zebroid") pattern with gray squamules ("as if a thin, gray surface layer had been peeled in numerous places"); context stuffed, off-white, unchanging when cut, with central cylinder 2.5± mm wide, with stuffing material of white fibrils (dense in part, loose in part); exannulate; universal veil as long narrow saccate volva, smooth, membranous, with exterior surface white, with interior surface pale grayish yellow to nearly white (above), only attached to stipe near very base of latter, 47 × 14 mm, 1.5 mm thick at mid-height of limb, having limbus internus with length varying in single specimen (in part, rather long). |
