Pisolithus Arhizus

Common Names: Black Jelly Roll, Dyeball, Dog Turd Fungus









Pisolithus arhizus, commonly known as the Dyemaker's Puffball or the Dog Turd Fungus, is a distinctive fungus notable for its peculiar appearance and ecological role. This species is found widely distributed across various continents including North America, Europe, and Australia, thriving in sandy soils and often in disturbed areas alongside roadsides and in open fields. The mushroom emerges from the soil as a dark, globular mass that may initially be mistaken for animal droppings. As it matures, the outer skin cracks to reveal a complex interior filled with powdery spores that range in color from yellow-brown to dark brown. The mature fruit bodies can reach up to 15 centimeters in diameter, making them quite conspicuous in their natural habitat. Ecologically, Pisolithus arhizus is a mycorrhizal fungus, forming beneficial associations with the roots of various tree species, especially pines and eucalypts. This symbiotic relationship enhances the host tree’s ability to absorb water and nutrients from the soil, particularly in poor soil conditions, thereby improving the plant's growth and survival rates. While not considered edible due to its bitter taste and tough texture, Pisolithus arhizus is valued in other fields. It is used in the dyeing of textiles, giving rich brown and gold hues, and is researched for its potential in bioremediation projects due to its ability to tolerate and thrive in contaminated environments. This robust mushroom is a fascinating example of nature’s complexity and adaptability.



Pisolithus arhizus is not typically consumed for its flavor, and when tasted, it is often described as bland or neutral.



The interior of the Pisolithus arhizus can have a gelatinous consistency, especially in its younger stages.


As the mushroom matures, it can develop a more rubbery texture.



Being a ground-growing mushroom, it has a natural earthy aroma.


It has a typical mushroom scent, especially when fresh.

  • Chemical analysis, moisture-preserving, and antioxidant activities of polysaccharides from Pholiota nameko by fractional precipitation

  • This study explored Pholiota nameko (P. nameko) polysaccharide fractions, PNP-40, PNP-60, and PNP-80, purified by gradient concentrations of ethanol (40%, 60%, and 80% (v/v)). The physicochemical properties, functional group composition, moisture-preserving, and antioxidant ability were determined. The results indicate that the polysaccharide contents of PNP-40, PNP-60, and PNP-80 are 45.12%, 78.04%, and 72.22%, respectively, while the β-glucan, protein, and uronic acid contents are 20.20%, 12.20%, and 10.15%, respectively; 11.24%, 14.53%, and 26.94%; and 5.99%, 7.73%, and 3.78%. Furthermore, PNP-60 has better moisture absorption, while PNP-80 has better antioxidant ability and H2O2-injury resistance activity

  • In May 1950 my husband undertook a pilgrimage to remote Serignan to see the Fabre water-colors, and he picked out more than a dozen for our book. Two years later, finding himself again in Paris, he called once more on Professor Heim, who by now had become the Director of the Museum National, a worthy successor in that great post to the illustrious Buffon. Indeed, he sits at Buffon's very table, in Buffon's very room, where the elegant i8th century furnishings have remained unchanged, the walls adorned with the graceful i8th century oils of Jean-Jacques Bachelier, depicting the birds of the several continents.


  • THIS book is addressed to those who love mushrooms, who love the whole rich world of wild mushrooms in the same way that many love the flowers of the field and the birds of the air. Our public is certainly one of the smallest in the English-speaking world, but no matter. We invite all to share our joys, and if few respond, we are not less happy for being few to savor the secret.
