mortenchristensen's Identifications

There were more immature spores dropped in print than mature spores, and I initially thought I had some kind of cross contamination.

Q=(1.2)1.5-1.8(2);N=30
Me=11.3x6.8um;Qe=1.7
Broadly ellipsoid/fusiform, smooth, variable levels of dextrinoid.
Print: White.
Basidioles: flexouse, slightly irregular.
Basida: Clavate 4-sterigmate, clamped.
Hymenial cystidia: Not found.
Pileipellis: A cutis of hyaline hyphae.
Clamp connections: Found only in basida.
Taste and odor: Very disagreeable.
