Observation 13844: Armillaria (Fr.) Staude
When: 2008-11-08
Herbarium specimen reported

Notes: Collected 11-8-08.

In a grass yard. Believed to be from underground roots of dead maple cut 2 years ago.

Not entirely ringless – slight annulus on some, and on some just a cottony appearance, but not as strongly ringed as pictures as A, mellia are. (Added observation 11-11-08: Also found some samples in this location with more distinct annulus ring, and very young specimens with cottony/cobweblike veil.)

Instead of dark short hairs at center of pileus, there were whitish fibrils on most. But some have a more typical darker appearance at center of cap. (Added observation on 11-11-08: as the specimens in the field aged, the hairs on the cap did darken to be more typical of A. mellia.)

Somewhat hygrophanous appearance.

Pleasant mushroomy odor. Taste also pleasant, very slightly astringent.

Spore print: white

Recognized by sight: I’m pretty sure that’s too much ring for A. tabescens, but I agree that A. mellea is unlikely. Perhaps our ‘local’ Armillaria expert will weigh in.
