Distribution and Habitat[edit]

Found in Palm Beach County, Florida and grows out of irrigated mulch beds. The holotype was collected in Jupiter, Florida.

Description[edit]

The cap is (9) 20–40 (58) mm diam., hygrophanous, lubricous to subviscid, glabrous, translucent-striate near the margin, margin decurved, broadly umbonate but can be acutely umbonate when young, white to light yellow when young, becoming medium brown or grey as the pileus dries out, with a dark blue to black or sometimes golden yellow to orange to brown or white umbo. Flesh bruising blueish. Lamellae adnexed, even, close to subdistant, ranging from white to rusty to light brown to dark purple brown. Fluoresces raspberry red in 365 nm UV along the gill edges. The stipe is (1) 2–7 (9) mm broad, 15–55 (64) mm long, central, smooth, fibrillose-striate, cylindric, equal, somewhat sub-bulbous, base sometimes hypogeous, whitish to sorrel brown, solid or hollow, with white radiating rhizomorphs at the base. Annulus membraneous, white, thick, persistent or very rarely evanescent, blueing with age. Context whitish to sorrel brown, bluing once cut. Odor is lightly farinaceous. Spore print is dark purplish-brown in color. Spores come in two distinct morphologies, the first being the rhomboid to subrhomoid shape you see in other closely related species but this species also produces a high proportion of uniquely shaped apically cleft or "heart-shaped" spores.


Taxonomy[edit]

The species was first collected in April of 2019 by Scott Ostuni and Andrew Chambers at the holotype location in Jupiter, Florida and officially described March 26th, 2024 in the journal McIlvainea. The name niveotropicalis comes from the latin niveo meaning snow-white and tropicalis referring to its tropical distribution.
