It is considered bruising if: you cut the sporocarp from either the base (left) or near the top (upper right) of the sporocarp. The rind is also referred to as the peridium, but I’ll bet you already knew that. Dr. Trappe was working with Guzman on identification of hypogeous and related fungi from Mexico several years ago. I believe he spoke at the North American Truffling Society once, but I was unable to attend that meeting. I think/thunk that most of Guzman’s work was in Mexico and the Caribbean, but I’m often wrong/incorrect/error-filled.
Nonetheless I’m excited about this collection: one I have not heard of before in the United States. Tends to prove that Scleroderma are much more widely dispersed than currently believed.
I find great promise in Scleroderma, since they are one of the first species I cultivated in my backyard after leaving one to dry on a wood-pile I had at the time there. Spores fell off the sporocarps from rainfall onto the ground next to an Italian spruce-pine, and next year were fruiting prolifically. Many are probably nonplussed about growing a probably poisonous fungus, but not I! Scleroderma are known to concentrate toxic metals, such as lead and mercury, and may have important roles in dealing with toxic waste clean-up as a result.
The skin of this mushroom is slightly yellow-brown towards the outside and white on the inside, but it does not stain yellow where damaged. Overnight it dried to a slightly darker shade but I would not call it staining. The reticle is calibrated and the divisions are 1.00 micrometers. I have the sample here so let me know if you need any more information or microscopy.
There is some yellow on the peridium, especially near the basal attachment, but also on the opposite side, visible when the first photo is enlarged to maximum. I’m not sure it is staining per se. Could be a smudge from handling, or a color transfer from your hands.
Can you post actual spore measurements, too? I can’t see any referent point. Thank you!
