Collection location: Sky Ranch, Contra Costa Co., California, USA [Click for map]

Who: David Pon (asthmaticsherpa)

No specimen available

Found on an oak twig (a hardwood) which suggests the genus Tremella, rather than Dacrymyces which grows on pine. Collection became very hard when dried, a characteristic described by Aurora in Demystified.


George Washington for size comparison.
Booger close-up. Eww!
400x magnification. Sample has been stained in phloxine and washed with KOH. Spores and hyphae visible. I was searching for basidium as a diagnostic tool to genus (cruciately septate for Tremella and tuning fork for Dacrymyces), to no avail.
