| intro |
The following text may make multiple use of each data field. The field may contain magenta text presenting data from a type study and/or revision of other original material cited in the protolog of the present taxon. Macroscopic descriptions in magenta are a combination of data from the protolog and additional observations made on the exiccata during revision of the cited original material. The same field may also contain black text, which is data from a revision of the present taxon (including non-type material and/or material not cited in the protolog). Paragraphs of black text will be labeled if further subdivision of this text is appropriate. 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 derived from the protolog of the present species, with molecular research of Hanss and Moreau (2020 [2017]) and S. D. Russell, and additional original research of RET. | ||||||||||||||||||||||||||||||||||||||||
| pileus | RET: gray-brown or occasionally white, unchanging, 30 - 55 mm wide, broadly campanulate in button, expanding to planar and umbonate, tacky to waxy, shiny on drying; context white, unchanging, 1- 4.5 mm thick, thinning evenly for 1/2 to 2/3 R, then membranous to margin; margin not appendiculate, striate (0.2 - 0.3 R); | ||||||||||||||||||||||||||||||||||||||||
| lamellae | RET: very narrowly adnate with faint decurrent line on stipe (10× lens), crowded, faint pinkish reflection in mass, very pale pinkish cream in button and white at maturity in side view, otherwise unchanging, 2.5 - 6 mm broad, broadest at 2/3 R length from stipe; lamellulae subtruncate, unevenly distributed, of diverse lengths, plentful. | ||||||||||||||||||||||||||||||||||||||||
| stipe | RET: 47 - 110 × 4 - 6.5 mm, white, becoming pale brownish from handling, with surface fibers concolorous, becoming brown with handling, narrowing upward, flaring slightly at apex (over ca. 5.5 mm), finely pulverulent-floccose above, with fine surface fibrils and occasionaly upward pointing scales below; context stuffed with white interwoven thread-like material, with some lacunae, white, unstaining, with central cylinder 1 - 3.5 mm wide, with larval tunnels concolorous; exannulate; universal veil as membranous, smooth, entirely white volval sack, no apparent layering, unitangent, with appressed limbus internus (in least mature specimen). 7 - 13.5 mm23 - 33 × | ||||||||||||||||||||||||||||||||||||||||

| ecology |
protolog: At 940 - 1770 m
elev. Under Corylus avellana alone or
mixed with other plants.
[Note: Details from

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.
