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 Jelly Spot

<em>Dacrymyces stillatus</em>, commonly known as the common jelly spot, is a saprotrophic fungus in the family Dacrymycetaceae. It is classified as Least Concern on the IUCN Red List, with records from five European countries and North America. The species typically grows on damp, dead, or decaying wood, particularly coniferous timber, forming small, gelatinous, orange-yellow cushions or pustules on the substrate surface. As a saprotrophic wood-decay fungus, it contributes to nutrient cycling and the decomposition of woody material in temperate forest ecosystems. The bright gelatinous fruiting bodies make it a conspicuous species when encountered on wet wood in cool, humid conditions. Diet information for this species is not available in current records. Biological traits of this species remain poorly documented in the scientific literature.
