Inside light-sealed boxes, Howalt has cultivated spores from selected fungal species directly onto unexposed analog photographic paper. As the fungi feed on the paper’s gelatin surface, they consume parts of the photographic emulsion, leaving behind traces that only appear once the paper is developed in the darkroom. The result is a series of photogram images created by the fungi themselves—organic compositions that reveal the delicate mycelium networks through the gradual deterioration of the paper. Other spores have been carefully grown in Petri dishes and scanned in high resolution, producing images that unveil a vivid, microscopic world of fungal forms and colors that normally remain unseen. In another process, Howalt grows fungi into paper-thin layers and leaves them to dry over several months. Once dried, these fragile, translucent sheets are used as unique fungal negatives in the darkroom.

Each image unfolds as a quiet dialogue between human intention and non-human agency: traces of life briefly lived on light-sensitive paper, marks formed through nourishment and erosion, fragile imprints of growth and decay, presence and disappearance.

At a time when fungi are increasingly recognised as key to the future of ecological balance, medicine, and sustainable innovation, the book gathers Howalt’s experimental works into a poetic and tactile volume, designed by the award-winning Rasmus Koch Studio and printed by Narayana Press, with accompanying texts by author Morten Søndergaard and mycologist Henning Knudsen.

Fungi is neither a scientific catalogue nor a botanical manual, but rather a poetic and visual meditation on fungi and their role in shaping life and matter. More than a mere recording of specimens, Howalt makes the fungi an integral part of the artistic exploration in a direct, tangible and co-creative way. The work crosses boundaries between science and art and touches upon questions relating to existential ecology, time and the phenomenology of photography, as well as the history of mycology. A reflection on transformation, coexistence, processes of image-making, and the unpredictable aesthetics of living organisms.
