Notes:

On a chunk of dead, fallen, rotting wood; on the underside, against the ground. The wood was rotting but still hard.

Asci: 8-spored, pore blued in iodine.

Ascospores: narrowly lacrymoiform, 5-7/2µm.

Paraphyses: 60/2µm, cylindric-fusiform, longer than the asci.

Excipital hairs: 75µm long, multi-septate, cylindric, 2µm diam, with swollen tips 3-4µm diam., granulate lower down or soemtimes over whole surface.

Drying: very pale buff; stalks often darker, pale orange; hairs remaining white. The discolouration may just be water wicking up from the substrate.
