Observation 61710: Irpex lacteus (Fr.) Fr.
When: 2011-01-01
No herbarium specimen

Notes: Found on small branch, under maple. (Most probably a maple branch.)

I would suggest maybe Schizopora sp. in Geneva, but not sure, the pore pattern is different. More random here, so not quite sure what this crust is.

This is typical young Irpex. When it ages the “pore” surface will break up even more.
Cerrena rarely grows on maple. When it is resupinate, which doesn’t happen often, just occasionally on the underside of the log, it always has the normal shelf-like fruiting body on the sides of the log. Also the pores are a little more maze-like and grayish in color.

For the people who voted for Irpex lacteus on this one (Erin, Noah), since I don’t know that one at all… what would you think about a suggestion of Cerrena unicolor in a resupinate form for this? The pore surface has the similar random maze-like pattern. If I found stuff that is Cerrena unicolor near by on birch, maybe this is a resupinate form on maple?
