Cercophora scortea (Cain) N. Lundq. 1972

Collected by Kitty Griffith

This voucher is located with S.M. Huhndorf's ascomycete collections at F. as S.M. Huhndorf 4131. The micrograph images by Andrew Miller show characteristic obpyriform (pear shaped) fruitbodies with setae (hairs). This species has gelatinous fruitbody walls.

Fig. Cercophora scortea 1. Fruitbodies (x25) with inset of single fruitbody (x50). 2. Mature brown-headed ascospores with inset of single ascospore showing dark brown head and pale brown tail.

In the "little black dots on wood" category is Cercophora scortea. Apparently this is only the second reported collection of this species in the United States; the first one being found in Louisiana by Gary Samuels. It was originally described from Canada and is also known in Europe. This specimen was cultured and studied by Andrew Miller and Sabine Huhndorf of The Field Museum as part of their investigation on the systematics of the Lasiosphaeriaceae. While carefully examining the various chunks of wood and branches on the identification tables, Andy found the Cercophora on wood with the jelly fungus Calocera cornea (voucher 1999-109).

Russula avellaneiceps Fatto 1999

Russulaceae, Russulales, Basidiomycota
Voucher specimen NAMA 1997-210
HOLOTYPE specimen, F
Prospector Campground, Summit, Colorado, USA
On soil under Lodgepole Pine.
15 August 1998
Collected by Debbie Johnson

The first NAMA foray that operated a voucher program resulted in a new species that was published: Ray M. Fatto, Three new species of Russula. Mycotaxon. 70:167-176. See record of this taxon on Index Fungorum or MycoBank. Half of collection is in the herbarium of Ray Fatto as RMF 101.

Ray Fatto contributed a great deal to the understanding of the American russulas.
