Having never seen F. Macount I can only quote Austin’s 
description of its spores: ‘Sports parviusculis subopacis den-

the table near F. Wrighti2. 
It is hoped that collectors will send in material illustrating 
more fully the distribution of this interesting genus. The 
Species all grow in sandy or clayey soil, closely creeping, and

Noted for Spores and report any modifications necessary in 
been figured in accessible works, e. g. Not. pro Fl. et Faun.
