The following is from the latest issue of MushRumors, the newsletter
of the Oregon Mycological Society, Vol 41, No. 6 (Nov-Dec. 2002):


	August 9, 2002, was a bigger day for OMS member, Adrian Beyerle, than
he had anticipated. Digging for truffles in Wasco County, he pulled
apart some wood layers and found - a truffle!@ But this was no
ordinary truffle. This proved to be a new genus, one that had
previously been identified by Dr. Alexander Smith, incorrectly as it
turned out, as a rhizopogon.
	Adrian was certain that it wasn't a rhizopogon but didn't know what
it was until Dr. Jim Trappe ID's it as a new genus, Hysterangioides.
Tack on beyerlea and you can add Hysterangioides beyerela to a long
list of distinguished fungal identities.
	So, whoever said that you needed a pig to find truffles?
	Congratulations, Adrian!

Comment by poster: I have found one reference to a Rhizopogon
hysterangioides in Smith, Smith and Weber's "How to know the
Non-gilled Mushrooms", Second Edition, c. 1981 by Wm. C. Brown Company
Publishers. The description of that species includes the following:

"3b Spores 11-14 x 4.5-6.5 microns.....R. hysterangioides Smith

Fruiting bodies 1-3 cm. nodulose to irregular, dry, dull white,
yellowish in the depressions, no rhizomorphs present; gleba of a dry
firm consistency; FeSo4 slowly pale bluish on the peridium; spores
yellowish in Melzer's; basidia clavate to subglobose above a wavy
pedicel; cystidia none; peridium of compactly interwoven hyphae 3-8
microns wide, no sphaerocysts present.

In duff under spruce and fir, central Idaho, August."

The photograph accompanying the MushRumors article shows Adrian with a
much large specimen, which appears black and perhaps 2 inches (5 cm.)
in diameter. Once again, a collection of an atypical secotoid fungi
proves to increase dramatically both the range and the characteristics
of the scientific knowledge.
