Pileus (cap): 
Pileus 10-13 mm broad, conical or convex, 
subviscid, hygrophanous, glabrous, striate, leathery 
brown to ochraceous brown.

Lamellae (Gills): 
Lamellae adnate, semi, grayish brown, at 
times slightly unevenly colored, with white edges. 

Stipe (stem):
Stipe 25-46 mm x 1-2.5 mm, cylindrical, stuffed, 
pale brown, fibrillose bluing occasionally where damaged.

Microscopic features: 
Spores 11.7-15.8 (-16.7) x 7.9-9.2 um, ellipsoidal, germ pore 
distinct, broad.  Basidia 25.8-34.2 x 9.2-12.1 um, 4-spored, 
hyaline, obovate or clavate. Cheilocystidia 22.5-35.9 (-44.2) x 5 -10 um, 
hyaline, long-necked, 6.7-15 um.  Pleurocystidia rare, 17.5-30.4 x 4.6-10 um, 
lageniform, long-necked. Subhymenium subcellular. Trama regular,
pale brown (5% KOH), with hyphae 3.3-15 um broad. Epicutis a layer of 
subgelatinised, encrusted hyphae with brown pigments, 2.5-5 urn broad, clamped. 

Season:
From when the fall rains begin until the first freezes. 
Liberty caps like cool temperatures, around 50 degrees Farenheit and lots of rain. 

Habit, Habitat, and Distribution:
Solitary to subgregarious on cow dung Reported from Western Australia, New Zealand, 
but was described in Tasmania.  

"Predominantly on nutrient-poor grasslands and pastures (Noordeloos 1999, p. 45), rarely on dung, 
 in contrast to the new species. Mating crosses between isolates of P. semilanceata and P. alutacea 
always produced negative pairings. "

Other Notes:
This species shares many macro and micromorphilogical characteristics 
with Psilocybe semilanceata, P. alutacea appears to be close 
to the blueing temperate dung loving species, It has been put into section 
Semilanceatae by Dr. Guzman.
