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 is based upon original research by R. E. Tulloss.

pileus

dark gray, nearly black over disc; universal veilabsent.

lamellae

becoming grayish with age.

stipe

thoroughly dark cinereous; exannulate; universal veil not present. [Note: Bottom of stipe missing.]

basidiospores

send to graphing tool

[20/1/1] (9.2-) 9.4 - 16.1 (-16.8) × (8.6-) 8.9 - 14.7 (-14.9) µm, (L = 12.0 µm; W = 10.6 µm; Q = 1.06 - 1.13 (-1.16); Q = 1.08), ??, smooth, inamyloid, subglobose to broadly ellipsoid, adaxially flattened.

ecology

Solitary. In bottomland hardwoods.

material examined

U.S.A.: LOUISIANA—St. Martin Parish - Lake Martin, 25.xi.2009 David P. Lewis s.n. (RET 458-3).

discussion

Evaluation of spore volumes indicates that 2-spored, or even 1-spored basidia were present in the material examined to date; hence, the average length, width and Q values cited above are probably high for an average mature specimen of this species. Removing the four largest spores from the data would yield [16/1/1] (9.2-) 9.4 - 12.6 × (8.6-) 8.9 - 11.2 (-11.9) µm, (L = 11.3 µm; W = 10.3 µm; Q = 1.06 - 1.13 (-1.16); Q = 1.09). The averages provided in this latter set of data would probably be close to those that would obtained in future, mature material of this entity, were such material to be collected.

name status	cryptonomen temporarium
author	Tulloss
cap	The cap is dark gray and black in the center; its margin is striate; and volval remnants are not present on the cap surface.
gills	The gills becoming sordid with age.
stem	The stem is thoroughly gray (dark cinereous). The universal veil at the stipe base reportedly breaks up easily.
spores	The spores measure (9.2-) 9.4 - 16.1 (-16.8) × (8.6-) 8.9 - 14.7 (-14.9) µm and are subglobose (infrequently broadly ellipsoid) and inamyloid. Clamps are not to be found at the bases of basidia.
