Brief Description:

According to Kuo et al. 2012: “Ridges glabrous or finely tomentose; dark
brown to nearly black, blackening with maturity and when dried; flattened when young but sometimes becoming sharpened or eroded with age. Pits primarily vertically elongated; finely tomentose; pale tan to brownish yellow. Stipe 20–35 mm high; 8–15 mm wide; more or less equal, or sometimes basally subclavate; finely mealy with whitish granules; whitish; developing fine ridges, or a few folds near the base, with maturity.”

Many specimens on MO from California and Arizona

that were DNA confirmed as M. brunnea were collected under conifers as Kuo expected: “Appearing under hardwoods, including A. menziesii and Quercus spp.; probably also to be expected in non-burned conifer forests; April. Specimens examined (SUPPLEMENTARY TABLE I) were collected in Oregon.”

Kuo’s macro description fits these obs quite well I think except that the stem which Kuo describes as white seems to turn pale orange in age.

Dark color even when young, stipes smooth and equal except subclavate with a few folds near the base in maturity, found in western North America. Kuo et al. 2012.
