Collection location: Luzerne Co., Pennsylvania, USA [Click for map]

Who: Dave W (Dave W)

Specimen available

Notes:
Found in an open area where landscaping had recently been done, including spreading some fill/soil.

Caps have small appressed scales; stipes with scaly/hairy patches.

Spores 5.5-7 × 3.5-4.5; the longest ones a bit longer than what is reported for P. terrestris. Spores with apical pore. Smash mount yielded numerous cylindrical to unevenly cylindrical cystidia, which matches the expectation for the cheilocystidia of P. terrestris.

Recognized by sight: Could be although in my experience angustipes is more of a dull drab brown color. Perhaps another species of pholiota.

look a lot like the mushrooms in this observation. P. angustipes has longer spores (also I surmise have larger Q) than P. terrestris. Along with the eastern NA occurrence and the (gill) cystidia perhaps more variably shaped than what is seen for terrestris (C du Q says the angustipes cheilocystidia are polymorphic), angustipes seems to make much more sense than terrestris for this observation.

Thanks Walt and Ryan.

P. terrestris is a western species. Looking at the obs. on MO it is very variable. P. angustipes is more Eastern. Kuo’s book has it misidentified as P. terrestris. That being said they are very close. My finds of P. angustipes have been in lawns under oak and at the base of a pine stump.
