Longispora

Longispora is a genus of fungi belonging to the family Parmulariaceae. This genus was first described in 1970 by mycologist Hans Sydow. Fungi in the genus Longispora are characterized by their distinctive ascocarps, which are typically small and spherical, often developing on the surface of plant tissues. The name "Longispora" itself refers to the elongated ascospores produced within these structures.

These fungi are primarily found in tropical and subtropical regions. They are often observed as leaf spot pathogens or as endophytes, meaning they live within plant tissues without causing apparent harm. Their host range can vary, and they are known to infect a diverse array of plant species, including various trees and shrubs. Research into the specific ecological roles and life cycles of Longispora species is ongoing, with much of the current understanding derived from taxonomic descriptions and observations of their occurrence on host plants. The genus currently contains a limited number of described species, and further molecular and morphological studies may lead to revisions in its classification.
