P. microsporus, Brefeld, “Bot. Unters.,” iv., 70, pi. 4., f. 16, 19-22

Stem slender, elongated; swelling ovoid; basal reservoir 
roundish, generally concealed; spores pale yellow or nearly 
colourless, equal, elliptic, 8-10 x 5-6,“. (PI. iv., fig. 16.) 
Stem 5-7 mm, high. Basal reservoir sometimes intercalary. 
Sporange black above, sometimes marked with hexagonal reticulations 
in white, one hexagon at the top, surrounded by a circle of others. 
Columella conical, dingy. Spores with no distinct epispore, not ger¬ 
minating in water, but only in a nutrient solution, somewhat flattened 
at the sides, having a greenish tinge in the mass. I have met with 
this species in company with P. Kleinii, each retaining its proper 
characters. Yan Tieghem’s contention, that the presence of the 
hexagonal reticulations is a specific character, is unfounded. 
On all kinds of dung; common. Paler than P. Kleinii.
