In 1885 he graduated from the University of Padua, where he studied natural sciences and chemistry with Pier Andrea Saccardo (1845-1920) and Francesco Filippuzzi (1824-1886). For several years, he worked as a librarian in the museum of Padua, afterwards teaching botany at the University of Camerino (1900). Following duties as a professor of botany in Sassari, he relocated to Modena, where from 1903, he served as a professor of botany and as associate director of the botanical garden.[1] During his career, he took numerous scientific trips throughout Europe — travels where he met and studied with scientists that included Jacob Georg Agardh (1813-1901), Alfred Mathieu Giard (1846-1908), Louis Mangin (1852-1937) and Narcisse Théophile Patouillard (1854-1926). He issued the exsiccata work Phycotheca Italica, collezione di alghe Italiane (1886-1889, with David Levi as co-editor) and the series Herbarium Phycologicum, collab. P. Hennings, G. Lagerheim, I. Strafforello (1896).[2]
His earlier work dealt mainly with plant systematics, his later research involved studies in the fields of phytophysiology and phytogeography.[3] In 1889 he began work on "Sylloge algarum omnium hucusque cognitarum", a massive project that was an index of all known algae. In collaboration with Saccardo, he made important contributions to "Sylloge Fungorum hucusque cognitorum" (index of fungi). As a naturalist-historian, he published a work on Leonardo da Vinci, titled "Le piante e gli animali in Leonardo da Vinci" (The plants and animals in (the works of) Leonardo da Vinci).[4]
From 1890, he was editor of the journal "La Nuova Notarisia", a quarterly magazine dedicated to the study of algae.
He was honoured in 1894, in the naming of Detonula, which is a genus of diatoms belonging to the family Thalassiosiraceae.[5] He was also honoured 1934, in Johannesbaptistia is a genus of brackish–freshwater cyanobacteria.[6]
