Clusterspike False Indigo

Amorpha crenulata, known as clusterspike false indigo or crenulate lead plant, is a critically endangered flowering shrub in the family Fabaceae with a highly restricted distribution confined to Miami-Dade County in southern Florida, USA. This species represents one of North America's rarest plants, with remaining populations numbering in the hundreds of individuals occurring in pine rockland habitat, an ecosystem itself ranked among the most imperiled in the United States. Pine rocklands are fire-dependent communities on exposed oolitic limestone, characterized by an open canopy of slash pine over diverse understory, and have been reduced to less than two percent of their historical extent by urban development in the Miami metropolitan area. Amorpha crenulata produces elongated spikes of small purple flowers typical of the genus and was historically more widespread across the Miami Rock Ridge before land development eliminated most habitat. Current populations exist primarily within Everglades National Park and a few private preserves. Its Critically Endangered status reflects the tiny remaining population, extreme habitat restriction, ongoing threats from urbanization, altered fire regimes, and sea-level rise that threatens low-elevation limestone habitats. Conservation efforts focus on habitat protection, controlled burning to maintain pine rockland structure, and ex situ seed banking.

Common Funnel

<em>Infundibulicybe gibba</em>, commonly known as the common funnel, is a saprotrophic fungus in the family Tricholomataceae. It has been documented in Denmark, Norway, Sweden, and the United States, and is known to occur more broadly across temperate regions of the Northern Hemisphere. The species typically inhabits forest floors and areas with decomposing wood and leaf litter, where it plays a key role in breaking down organic matter and recycling nutrients. <em>Infundibulicybe gibba</em> produces characteristic funnel-shaped fruiting bodies, typically pale buff to pinkish-tan in color, with deeply decurrent gills running down the stipe. It is assessed as Least Concern, reflecting its wide distribution and occurrence across a variety of woodland habitats. The common funnel is a common and recognizable species in temperate forests throughout its range. Biological traits of this species remain poorly documented in the scientific literature. As a saprotroph, it contributes to decomposition processes in forest ecosystems and is often found growing in arcs or rings in leaf litter and grassy clearings within woodland areas.
