Observation 66554: Non-fungal

When: 2011-04-06

Collection location: Washington DC, USA [Click for map]

Who: Martin Livezey (MLivezey)

No specimen available

This fruiting has an almost cementious or ceramic outer shell – it is not soft as in the last observation of the same name. Both seem attached to a very sturdy scerotium and are probably the same individual. I will probably need a large mallet and a volunteer to get this one opened up.

Wrong genus?

Noah … I must reconsider my original observation of Calvatia tigris-woodsii, http://mushroomobserver.org/25143?q=4Mpp I have been examining the voucher specimen, but have made no headway in the past year in obtaining a cross section through traditional means (a butter knife). Your section causes me to suspect that this is actually a species of Scleroderma.


Oops …

let Curecat know this stuff is ‘clogging up the database’. She was worried about it before.

This mushroom should have it’s own observation. Calvatia tigris-woodsii var Santa Cruz, I suspect, as I have never seen the specific red-and-green marking before. The cross-section indicates a density akin to a truffle, hence I propose a new name: Tuber tigris-woodsi var Santa Cruz. It was probably dug up by a flying squirrel.

Could you provide a thin section at magnification to confirm?

I had no idea …

It’s tough to ID to species without one.
Here is an example on what to do…
