Collection location: San Francisco State University, San Francisco, California, USA [Click for map]

Who: PolloAsado

No specimen available

Free gill attachment; Smooth, white, slightly dextrinoid spores; Sub-parallel hymenophoral trama.

Due to the “deer-antlered” pleuro’s, I had been convinced I was looking at Pluteus cervinus. The non-convergent gill trama convinced me otherwise.

The section I had taken of the gill trama hadn’t been the cleanest cut I’ve made. The alignment of the hyphae should have been more conspicuous. Nonetheless, It may have been convergent. There are no remnants of any preexisting veil and my spore color ID was through a scope with a yellow tinted incandescent bulb. Pluteus it is.

overwhelm the errant trama (photos?). Spore color? Everything about this thing screams Pluteus. I don’t know of any Lepiota with horned cystidia.
