Observation 183153: Pisolithus Alb. & Schwein.

When: 2014-10-10

Collection location: Del Mar, California, USA [Click for map]

Who: Jacob Kalichman (Pulk)

Specimen available

With pine.

Sporocarp with two big lumps adjacent to one big depression.

Peridium white; fading to tan in areas with harder lives (sporocarp top; more messed up side).

Peridium splitting in generally horizontal streaks, exposing a darker beige/tan solid-colored layer beneath, then exposing the (now-dried new surface of the) mottled interior.

Some small bumps are affected as above. I suspect that to be either peridioles inside pushing out against the peridium, or (more likely) the peridium shrinking around the peridioles as it dries out.

In peridium woulds, lots of the exposed interior gets a solid a charcoal surface… seems like more black than there should be inside… hmm.

Distinct craters through the peridium might be chewogenic.

Pink-tinted splotches around the upper lower and lower upper parts of the sporocarp peridium.

No yellow at the sporocarp base. The root is solid black with hints in some places of yellow.


Layer 1.
- Tough mass, mottling radiating outwards and upwards from a small central area (i.e., root apex). When broken, splits into a rough surface.
- Mottled white, black, yellow, and brown.
- When cut, appears black with bits and hints of dark yellow.

Layer 2.
- Less tough, not blatantly radiating out. It’s doing its own thing now.
- Mottled black/yellow, mottled with white. Clearly more white area than black/yellow.
- The white areas very easily stain yellow. Appears to be due to being combined with the black mass surrounding it.
- When cut, appears black with dark yellow spots.

Layer 3.
- Peridioles become distinct. When broken, splits around the peridioles.
- Exteriors white with slight pink tint developing quickly.
- Exteriors still easily stain yellow.
- Interiors are a pastel-colored (yellow to white to pink) jelly.
- Interiors when agitated easily darken to bronze (or even ruby), maybe from the white, red, yellow, and black stuff combining.
- Interperidiole substance (what do you call this?) is black with yellow streaks.

Layer 4.
- Exteriors dull olive, finely rough appearance.
- Exteriors, agitated, easily reveal interior.
- Interiors are a dark purple-black jelly. Maturation from the previous pastels proceeds from the middle of the peridiole outwards.
- Interperidiole substance is greenish black with yellow streaks, and will remain so.

Layer 5.
- Exteriors dull yellow, finely rough appearance.
- Exteriors, agitated, easily reveal interior.
- Interiors are a chocolate brown paste (to Layer 5b, densely packed spore mass)

Layer 6.
- Former exteriors & interperidiole substance become brittle and fade away.
- “Interiors” are a chocolate brown spore mass held vaguely intact by cottony wisps.
