'I scanned the forest floor around me. I couldn't yet see fungi, but I could smell them. Lowering my nose to the ground, I inhaled a distinctive fungal funk. I rolled over some bark and there they were!' This book is about fungi, and the photography of fungi. The title - Funga Obscura - unites the two. Beginning in elemental landscapes of ice and rock, the book traces the evolutionary path of fungi as enablers of life on land, and creators of soils and forests. Crossing continents and ecosystems, we navigate lichen-covered landscapes, crawl in the fungal undergrowth, scale glacial extremes and duck between rainforest shadows.
