Due to delays in data processing at GenBank, some accession numbers may lead to unreleased (pending) pages.
These pages will eventually be made live, so try again later.
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 text is based on original research of R. E. Tulloss.
59 mm wide, pale gray or pearly gray, with dark gray disk, no brown tones when fresh, planoconvex, umbonate; context white to off-white, very thin; margin tuberculate striate (0.5R), nonappendiculate; universal veil absent.
narrowly adnate with decurrent tooth, close to subcrowded, white to off-white in mass, ?? mm broad; lamellulae truncate, unevenly distributed.
130 × 5.5 mm, white, narrowing upward, flaring at apex, with brownish gray fibrils on lower half; context white, hollow, with central cylinder ?? mm wide; exannulate; universal veil submembranous, white, but limbs becoming gray and collapsing on stipe, base of volva remaining white with ochraceous stains, 20.5 mm from base of stipe to highest point on limb.
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.
