is probable that several other species exist in our district but from

GENUS 82. PHYSARUM.* P. 
Peridium simple, membranaceous, naked, smooth, bursting irre- 
gularly, columella none. 
1.—Physarum nutans v aureum. P. Grey. t 124. On rotten

Peridium Membranaceous, opening by a longitudinal fissure ; 
flocci adherent to the peridium on all sides, reticulate, flat, ending 
above in an inner peridium.
