Collection location: Ricketts Glen State Park, Pennsylvania, USA [Click for map]

Who: Dave W (Dave W)

Specimen available

On mixture of soil, mulch, and wood chips spread along the perimeter of an area recently landscaped.

Spores ~8-10 × 4-4.5, longer and somewhat thinner than dimensions reported by C du Q. Mainly ovoid but many with a small depression in the midsection that may be due to a partially collapsed wall… or perhaps the perception of shape varies according to the position/profile of the spore. A few with single observable oil drop.

Spore print yellowish/ochre.

that T. conspersa is unlikely? As seen in the photos, these were growing on more or less bare ground (in an area where mulch had been spread).
