BRIEF DESCRIPTION: The description is largely based on the original description (Wood 1997).

The cap of A. crematelloides is up to 40 mm wide, convex to flat convex, finally plane or a little depressed at the center, smooth, dry, with a margin striate up to one-third of cap's radius, pallid cream to pale cream-gray, center sometimes a little deeper colored. Volva remains on the cap are thin, mealy or granular; and concolorous with the surface or a little darker; occasionally, there are vague warts over irregular areas.

Gills are free, thin, crowded, pale cream, with a concolorous margin, sometimes slightly serrate. The short gills are present in at least one series.

The stem is up to 40 × 5 mm, white, smooth, without any trace of a ring. The basal bulb is small, ovoid, cream-gray, with distinct small, mealy ridge or distinct margin at the top, but no free limb.

The spores measure (6.6-) 7.2 - 9.0 (-9.9) × (6.0-) 6.6 - 8.4 (-9.3) µm and are subglobose to broadly ellipsoid and inamyloid.  Clamps are absent at bases of basidia.

Wood described this species as occurring in sclerophyll forests in the state of New South Wales, Australia. A sclerophyll forest in the Australian bush is a forest of hard-leaved plants including Eucalyptus in the overstory (wikipedia).
