Observation 19114: Postia caesia group

When: 2009-03-03

Collection location: Parque Nacional Tierra del Fuego, Tierra del Fuego, Argentina [Click for map]

Who: Jason Hollinger (jason)

No specimen available

Notes:
No specimen — no way to dry a thick shelf mushroom in just one day.

Shelf on big Nothofagus pumilio log, somewhat spongy-soft (but still tough enough to be difficult to cut into); CAP all white except for long curved dark bristles all over top (remniscent of Hexagonia hydnoides in texture); FLESH solid white, about 1 cm thick; TUBES white, about 1 cm thick, tiny (about 4 per mm), ends eroded making it quite tooth-like, exudes clear colorless liquid when squeezed.

(First photo wasn’t color-balanced correctly: it is not as yellowish as it appears there.)
