Observation 102918: Panaeolus subbalteatus (Berk. & Broome) Sacc.

When: 2012-07-23

Collection location: South Jordan, Utah, USA [Click for map]

Who: Ryan Thurber (Thurbs)

Specimen available

Growing all over the lawn which topsoil & sawed had been laid 3 or 4 months ago, we’ve had a couple of rainy days & just the right temperature, I’ve looked all over online & I’ve found no info on LBM’s in Utah so I’ve decided this is a topic worth putting out there for experts to tackle!

*Panaeolus? Panaeolina? Galerina?
*Fresh topsoil & sawed
*Mulched grass
*No noticeable bruising, but I’ll be making more observations
*One of the mushrooms had a bluish white shade of mycelium(I realize there are a couple of different types)
*Most spore prints were black a couple were brown
*I have atleast 3 different LBM’s I would like identified, & I have no problem with anyone editing/correcting anything I’ve written here, also if i’ve uploaded too many photos of the same one! Thanks!(I will change the info myself if needed once I’m corrected)

Proposed Names

Recognized by sight: The species concept of Agaricus (Panaeolus) cinctulus is based on a drawing made by Bolton in 1791. No type collection exists. Since it is not possible to know whether Bolton’s species was Panaeolus subbalteatus, P. olivaceus or P. fimicola, I consider Panaeolus cinctulus to be a nomen dubium.
Based on microscopic features: The gill faces need to be checked for sulphidia; the presence of these would indicate that it is probably Panaeolus fimicola.
