Weights of rhizomorphs of undetermined Armillaria sp. obtained using ring‐trench and core soil sampling methods around aspen stumps in stands at different intervals after harvest were correlated. The core method was used to sample a second series of stands twice (at an interval of two growing seasons) at radial distances of 0.5, 1.0, and 1.5 meters from stump centers. Stands were uncut (at both samplings) or 3, 6, 9, 12, or 15 years after harvest (at the time of the initial sampling). Rhizomorphs were obtained from less than half the cores from the uncut stand, and the quantities (weights and lengths) were relatively small from both samplings. Mean numbers of soil cores yielding rhizomorphs and the mean quantities obtained generally increased as a function of the interval after harvest (and from the first to the second sampling), except for the oldest stand.
