Collection location: Flemington, New Jersey, USA [Click for map]

Who: Linas Kudzma (baravykas)

Specimen available

Small light brown colored Inocybe sp. growing from the ground in mixed woods. Caps are 1 cm or less in diameter and are fibrous and radially striated. Spore print was brown and spores are nodulose with pronounced spikes. The 20 spore average size was 10.0 × 7.4 microns and average Q=1.36. Encrusted metuloid cystidia are abundant and remain colorless in 5% KOH. See photomicrographs for shapes of spores and cystidia.


Forgot my mini-ruler, so a US penny for scale. These are the smallest Inocybe I’ve collected.
This is a stack of 8 images taken in rapid succession at differing focus to increase the depth of field. I used Zerene Stacker software.
