erythrospora
Erythrospora is a historical taxonomic name that has appeared in various biological literatures to describe organisms associated with red-colored spores or sporangial structures. The term derives from the Greek erythros meaning red and spora meaning seed or spore. Because it has been applied inconsistently across different groups and time periods, Erythrospora is not retained as a single, widely accepted genus in modern taxonomy.
In older mycological and phycological works, some authors assigned red-spored forms to a genus called Erythrospora.
Because the name lacks a stable, well-defined circumscription, there is no universal morphological or ecological profile
