Observation 10165: Laetiporus gilbertsonii Burds.
When: 2008-08-27
Herbarium specimen reported

Notes: I found this growing on a wounded limb of a carob tree on Linda Vista. It is rather soft and watery.

September 1 update: it is now growing in profusion on 7 out of 43 carob trees in the vicinity, with signs of previous year’s growth on at least two others. No question about its identity now. Wonderful creatures!

Sorry, Darvin, I can never remember the scientific name of carob’s wen I need it. Too late now, but it is Ceratonia siliqua. Very much a deciduous tree.

There is quite a striking affinity of Laetiporus gilbertsonii for carob trees (Ceratonia siliqua) in southern California. I’ve been checking out every carob tree I see lately, and sure enough about 1 out of 4 or 5 throughout Pasadena, Sierra Madre, Santa Anita, South Pasadena, and San Marino are sporting lovely growths of this spectacular fungus. I’ve only once found a Laetiporus growing on something else. Who knew?
