|spores||The spores of the present species measure (9.8-) 10.0 - 11.8 (-12.5) × (5.8-) 6.0 - 7.5 µm and are ellipsoid to elongate and inamyloid. Clamps are probably absent at bases of basidia.|

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.

The following text is derived from molecular studies of L. V. Kudzma and from other original research of R. E. Tulloss.
|pileus||63 mm wide, brownish orange, losing some of the orange tint with time, becoming yellowish gray, browner and darker over umbo, virgate, planar, with rather broad central umbo, tacky; context off-white, brownish or grayish tint in very shallow region below pileipellis, unchanging, 4.5 mm thick over stipe, thinning evenly for about two-thirds radius, them as membrane to margin; margin nonappendiculate, striate (0.2–0.25R), decurved; universal veil as pallid small patches and flat warts with apparently fibrillose upper surfaces, pallid at first, becoming distinctly yellowish, subfelted.|
|lamellae||free, with weak imcomplete irregularly distributed broken decurrent lines (10× lens) on stipe apex, crowded, cream in mass, whiter than pileus context in side view, with some small areas of browning near lamella edges, 6.5 mm wide, apparently not marginate; lamellulae truncate (especially the longer lamellulae) or subattenuate, unevenly distributed, of diverse lengths, rather common.|
|stipe||156 × 7 mm, off-white, becoming palely sordid yellowish from handling, cylindric to subsinuous, flaring at apex, originally with punctate surface in upper 20–30 mm, becoming fibrillose below this zone, with fibrils brown to gray or black continuing to with 30 mm of stipe base, then surface becoming substrangulate down to greatest mass of volval remnants, bottom of stipe dog-legged; context ??, with insect tunnels concolorous, stuffed with longitudinally oriented subtranslucent white fibers, with central cylinder 2.5 mm wide; exannulate; universal veil as warts or small patches, white on exterior surface with pale grayish interior surface, smooth, submembranous, with fragments distributed unevenly [with isolated individual warts as well as two irregular rings of warts (one at top of substrangulate zone and one at its lower end], distributed up to 42 mm above stipe base.|
|odor/taste||Odor not detected; taste not recorded.|
|ecology||Solitary. After a period of heat between 30° and 40° C followed by several days of drenching rains. In dark loam.|
|material examined||U.S.A.: CONNECTICUT—New London Co. - Colchester, Day Pond St. Pk. [41.5639° N/ 72.4183° W, 134 m], 25.viii.2007 “Karen” s.n. [RET 8-25-07-B] (RET 438-4, nrITS & nrLSU seq'd.).|
A. sp-N58 is
somewhat similar in gross appearance.|
The nrITs and nrLSU sequences derived from the original collection of this code-numbered taxon provide a clear indication that A. sp-N49 can be assigned to sect. Vaginatae and to the provisional ssubsection Penetratrices (see the techtab on the A. penetratrix page). Also, the sequences indicated the present entity is distinct from all others that we have sequenced in the Vaginatae with the exception of A. sp-N58.
Existing sequence data for the present species indicates it is distinct from all sequences previously deposited in GenBank.

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.
