cap | The cap is pale tannish gray, a bit darker in the center, uniformly more grayish brown with age, sometimes bearing a graying volval patch, and with marginal striations occupying 15-20% of the cap's radius. |
stem | The stem is often distinctly pointed at its base and distinctly connected to a narrowly expanding cluster of downward-directed white hyphae that appear to holed the position of the fruiting body in the growing zone of the Sphagnum in which the fruiting body develops. The volva at the stem's base fragmente easily and becomes gray before maturity. |
spores | The spores measure (9.6-) 9.9 - 12.4 (-14.8) × (7.2-) 7.9 - 11.3 (-14.0) µm and are subglobose to broadly ellipsoid (infrequently ellipsoid) and inamyloid. Clamp information t.b.d. |
discussion |
This species is somewhat reminiscent of A. sinicoflava Tulloss. The present entity is known only from southern Labrador, occurring in Sphagnum well above the level of any soil, in Atlantic coastal boreal forest of Balsam Fir (Abies balsamea), Birch species (Betula ) (including some dwarf species), Larch (Larix laricina), and Spruce (Picea).—R.

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. | ||||||||||||
basidiospores | [27/2/1] (9.6-) 9.9 - 12.4 (-14.8) × (7.2-) 7.9 - 11.3 (-14.0) µm, (L = 10.8 - 11.2 µm; L’ = 11.1 µm; W = 9.5 - 9.8 µm; W’ = 9.7 µm; Q = (1.06-) 1.08 - 1.24 (-1.50); Q = 1.14 - 1.16; Q’ = 1.16), colorless, hyaline, inamyloid, smooth, thin-walled, subglobose to broadly ellipsoid, infrequently ellipsoid; apiculus sublateral, cylindric; contents dominantly monoguttulate with or without additional small granules; color in deposit unknown. | ||||||||||||
ecology | Paired. Near sea level. In deep moss under tuckamore (close forest compressed by winds) comprising Abies, Betula (including dwarf species), Larix, and Picea. | ||||||||||||

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.
