Recognized by sight: yellow-fleshed, blue staining, reported from Colombia and US Virgin Islands.
Used references: Akers, Brian P., Sherri A. Angels & James W. Kimbrough. “Leucoagaricus viridiflavoides, a new species from Florida, with notes on related taxa.” Mycotaxon 76: 39-50. 2000.
Based on microscopic features: should have “basally truncate, spurred basidiospores which lack an apical pore. In addition, it lacks pleurocystidia, and has clamp connections…”

Based on microscopic features: “Basidiospores 5.3-11(-13) x 3.4-5.1(-6) um (Q = 1.81); ellipsoidal to ovoid to amygdaliform to arachiform (”peanut-shaped"), smooth, hilar appendix prominent, wall thick (0.5 um)… Cheilocystidia 29-51 × 7-13.2 um, abundant, clavate to slightly ventricose or more often ventricose-rostrate with a well-developed apical appendage… walls smooth, thin; pale ripe black olive in water, hyaline in KOH. Pleurocystidia 27.5-36 × 6.2-18 um, scattered, narrowly to stoutly clavate with apical appendage papillate to articulated, short-rostrate; walls smooth, thin; hyaline in KOH."
