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.
88 mm wide, slightly reddish brown to brown, rather uniformly pigmented, unchanging when cut or bruised, campanulate, subviscid to tacky, subshiny to shiny; context off-white, brownish below pileipellis, unchanging when cut or bruised, 6 mm thick at stipe, thinning evenly for four-fifths radius, then membranous to margin; margin striate (0.25R), nonappendiculate; universal veil as patches of confluent warts, white at first becoming gray with high points darker, eventually nearly black, detersile, felted-floccose to pulverulent (lens).
free, without decurrent line on stipe, subcrowded to crowded, off-white in mass, sordid white in side view, unchanging when cut or bruised, 5 mm broad; lamellulae truncate, variable as to length, some arising at stipe rather than at pileus margin, unevenly distributed.
145 × 14.5 mm, pale brownish cream, browning due to loss of pulverulence, narrowing upward, not flaring at apex, pulverulence (paler than stipe ground color) above becoming fibrillose below, with fibrils becoming red-brown from handling, not in a chevron-like pattern; context white, unchanging when cut or bruised, hollow, with central cylinder 8 mm wide and lined with white cottony fibrils; exannulate; universal veil distributed around strangulate region of stipe base, with rather large, submembranous patches on lower stipe above strangulate region (uppermost of these patches pale gray and lower ones white), with white appressed cup at stipe base, 41 mm from highest point of patches to base of stipe, highest point of strangulated region 29 mm from stipe base.
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.
