. In addition, mature basidiomes are much larger than other whitish small-spored species.

also has more strongly ellipsoid spores (Q values averaging 1.66) than other species. Historically,

<taxonomicName lsidName="H. albomagnum" pageId="0" pageNumber="35" rank="species" species="albomagnum">H. albomagnum</taxonomicName>

has been less frequently collected than other pale species of

|

, perhaps because the basidiomes are often buried underneath layers of needle and leaf litter and thus overlooked. As basidiomes emerge from the ground, leaf litter remains stuck to the matt glabrous surface of the pileus, masking its appearance. This characteristic, along with the creamy white coloration, large basidiome size, and small ellipsoid spores, makes this one of the easier
