Spores (in KOH) of small fibrecap mushroom Inocybe calospora(?) collected in Hensel Park. College Station, Texas, May 8, 2023Observations of the fungus Inocybe calospora in East and Central Texas reveal distinct characteristics. On May 8, 2023, a small fibrecap mushroom, potentially Inocybe calospora, was found in Hensel Park, College Station, Texas. The mushroom's spores were observed to be shaped like ocean mines. A side view of the mushroom provided further detail on its morphology.
