Dye-maker's False Puffball Pisolithus arhizus (Scopoli) Rauschert    Synonyms: Pisolithus tinctorius.
Kingdom Fungi   >   Phylum Basidiomycota   >   Class Agaricomycetes   >   Order Boletales   >   Family Sclerodermataceae   >   Genus Pisolithus   

Status:

Found solitary or in groups on ground (often in infertile, sandy soil); mycorrhizal, especially with pines and oaks.

Description:

Fruiting body variable in shape, usually oval to club-shaped with a stalk-like rooting base; smooth; yellowish to brown. Outer layer splits irregularly, exposing spore cases embedded in a black gelatinous material; spores at maturity brown, powdery. (J. Solem, pers. comm.)

Relationships:

This species is an important mycorrhizal fungus for newly established pine forests. Like Thelephora, it is often inoculated onto pine roots. The blackish jelly has the capability of staining cloth with a bright olivaceous yellow pigment, which is quite valuable in the wool-dying industry. (L. Biechele, pers. comm.)
