Trappea phillipsii
Mycotaxon 38: 7. 1990
Common Name: none
Basionym: Hysterangium phillipsii Harkn.
For descriptions see Siegel et al. & Castellano
Hypogeous in dryer woodlands; mountains, coast, and foothills. Widely distributed but very rare.
Unknown.
Trappea phillispsii can be distinguished by its dark to bright green gleba with a sterile whitish band near the peridium and its whitish gleba that quickly stains bright pink to pinkish brown when handled. Trappea darkeri is similar, but stains orange-brown, yellow-brown to brown rather than pink. Hysterangium species are similar but can be distinguished by a lack of a persistent layer of sterile locules located just within the peridium and its smooth and typically larger spores.
