Who: Ron Pastorino (Ronpast)

No specimen available

These were found in the Big Sandy Creek Unit.
Caps were small, up to 11 mm across and stipes 20 mm long.
The stipe was scruffy with whitish granules and longitudinally ridged.
Could not get a spore print but spores did appear to be brownish in KOH.
Spores were very nodulose and ~ 9-11 X 7-7.5 microns.
Cystidia on the gills was mostly utriform.

for assigning a potential species name to one type of Inocybe that occasionally occurs on my lawn.


Spores are stellate.

Thanks Irene, they really do look

like a match for I. asterospora and if there were any other North American sightings, it would be a no-brainer.
Interestingly, I found another couple in a different area of the Big Thicket that appeared to be the same species. They were a little larger, ~ 22mm caps, and with the same distinctive spores. I didn’t post them because my photo of them was rather poor.
