| 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 | 43± - 65± mm wide, pale creamy tan or pale yellowish tan, broadly campanulate to convex, becoming planoconvex, ??; context predominantly white, with pale orangish tan region below pileipellis in disc, unchanging when cut or bruised, 4 - 8± mm thick above stipe, narrowing evenly to margin; margin nonappendiculate, striate (ca. 0.15R), remaining decurved when pileus otherwise nearly planar; universal veil as felted-fibrillose confluent warts and patches, detersile (at least at first) and sometimes pendent to some length from pileus margin, probably orange at first becoming pale orangish cream or orangish white, with wart surfaces appearing as disorderly mass of interwoven fibers at 12×. | ||||||||||||||||||||
| lamellae | free with decurrent lines on upper stipe, close to subcrowded, pale yellow-orangish cream in mass, cream in side view, pale orangish cream in exsiccata, 6 - 9± mm broad, broadest at about 75% of gill length from stipe, ??, with edges pallid and minutely fimbriate is exsiccata; lamellulae truncate to rounded truncate, infrequently attenuate, common, not between every pare of otherwise adjacent lamellae, of diverse lengths. | ||||||||||||||||||||
| stipe | 54 - 70± × 9 - 12± mm, with pale cream to whitish base color, subcylindric, decorated with dene orange coating of longitudinally oriented fibers suggesting an animal pelt, with these fibers fading in color with age and exposure, ??, with expose stipe surface or context longitudinally striatulate; bulb 10 - 11± × 13 - 15± mm, turbinate to obconic, with proportionately thick raised margin in dried material, ??; contents white, unchanging when cut, loosely stuffed with white cottony material or hollow above bulb, with central cylinder 3 - 6± mm wide, continuing into bulb for about half length of bulb and there stuffed more persitently than in stipe; exannulate; universal veil sometimes as thin orange exterior layer on bulb in exsiccata, apparently leaving broken ring of limbus internus on lower stipe at lower end of orange fibrillose covering of stipe and apparently connected to this covering on upper side of ring. | ||||||||||||||||||||

| discussion |
The universal veil on the cap is often much more strongly orange on the bottoms of warts than it is on top of them. This probably indicates that UV light and or drying or other effects of exposure bleach the surface of a wart that was originally entirely the color of its basal part. When first encountered, this species was mistaken for another Pine Barrens species with a paler, less dense, orange, felted covering of much of the stipe—A. dulciarii. The later species has a browner cap, globose to subglobose spores, and lacks a bulb at the stipe base—it is assignable to sect. Vaginatae. | ||||||||||||||||||||

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.
