Growing abundantly in mulch among Rhus aromatica behind Townshend Hall. Annulus lacking. Veil remants on cap margins. Caps without separable pellicles. Odor not distinctive. All structures inamyloid. Monomitic with at least some clamps present. Pileipellis composed of encrusted hyphae. Pleurocystidia absent. Cheilocystidia abundant, mostly ventricose mucronate. Cheilocystidia measurements from Piximetre: (21.5) 22.1 – 28.1 (28.8) × (7.5) 8.4 – 9.3 (9.5) µm, Q = (2.3) 2.5 – 3.2 (3.7); N = 15, Me = 24.9 × 8.8 µm; Qe = 2.8

Keys to R. austrinum, but def looks like a hybrid - with both austrinum and canescens occurring in the same spot. It’s very unusual to have both species occurring in the same location, only seen it at one other location.

Growing in duff under a black cherry. Oaks, beech and sugar maple further away. I crush-mounted a section of the excipular surface (in 5% KOH and phloxine) and examined it under my 100x lens. I think the structures I found were excipular hairs since they didn’t contain the pigments that the paraphyses do and they were smaller than the regular hyphae. I’m not really sure though. The blobs in the pictures are lens oil that got under the cover slip.

My 6 yr old daughter spotted her munching on a Harmonia axyridis inside a dead leaf hung up in the remnant of her web alongside our shed. Hopefully she's gravid, sticks around, and leaves us an egg sac for the spring!

Growing in soil squeezed between the bases of the fronds of a small fern. I would have called it Inocybe in the field, except the gills were absolutely pure white and there was no smell.

Additional notes for sequences (bases on the right):

ITS: Sequenced by Matthew Smith lab, especially Ben Lemmond

Small, the largest cap was 1-inch, on a decorticated conifer log.
Pileipellis with clamps.
Pleurocystidia with small hooks.
Plenty of cheilocystidia and intermediate cystidia in various of shapes.
Basidiospores in KOH

Q = (1.3) 1.31 - 1.55 (1.6) ; N = 25

Red gills, purplish stipe, brown powdery cap with torn veil fragments at margin, annulus high on stipe. Powdery surface on stipe, purple underneath. Cannot recall an odor. Seems to have reddish-brown-maroon spores. There is a brown red powder on my hand near the gills. Did not take spore print. Collected and dried, only specimen observed.
