Observation 4279: Tulostoma Pers.

When: 2007-10-07

Collection location: Santa Rosa, Sonoma Co., California, USA [Click for map]

Who: Debbie Drechsler (debdrex)

No specimen available

Two found fruiting in dirt where a street tree (still working on the id) was planted. When I saw that they had no gills or tubes I wasn’t sure what I’d found until I remember seeing pictures of stalked puffballs. I thought they only occurred in desert or sand environments.

Pileus: 2.6cm broad, bottom looks and feels like dirt, with a collar, loosely fitted, around the stipe. It appears to have covered the whole and is now peeling back. Top has pinkish-gray almost papery thin covering, which peeled back (probably due to rather rough handling) to reveal dingy mustard-yellow spores.

Stipe: white at base turning redwood brown then shaggy and bark-like. 1.1 cm long and 2mm wide at stalk.

Arora mentions rusty-salmon spore mass but in all other regards this seems to be a perfect fit as an identification.
