-PSILOCYBE CUBENSIS-

The CAP is 1/2 inch to 4 inches wide. For the first few hours
cone-shaped, quickly becomes convex, then flat and finally edges uplift,
forming a bowl-shaped cap in the mature mushroom (age 24-48 hours after the
rain). The bowl-shaped cap will have an umbo or may become a depression. A
sticky protective film will be observed over the entire cap in fresh
specimens. The color varies widely, from an almost pure white with a gold
center-spot to an overall light-brown still retaining the gold center-spot.
This species becomes translucent when it has absorbed excess water. At this
time the cap (except for the center spot) will appear a dark-olive which is
actually the dark spore color showing through. Both the water-soaked and
normal specimens will dry to a yellow-rust color still retaining the
orange-to-gold center spot.
The GILLS are rather closely spaceed and are light-brown in the young
stages, becoming a deep purple or black with maturity. In early stages the
gills will be connected to the stem but may separate with age.
The STEM will be from 1.5 inches to almost 6 inches tall and up to 1/2
inch thick. The stem base (volva) is many times, although not always,
thickened. The stem will be hollow, fibrous and generally white or at least a
lighter color than the cap. There will usually be a ring of tissue hanging on
the upper portion of the stem (the veil) which usually turns blue with age.
The inside flesh of the broken stem will usually yield the fastest bluingreaction.
The FLESH of this species is white, has little odor and tastes like fresh
grain. It is usually located on cow-manure (although it is located on the
manure of other grain-fed animals as well) or on soil that has been enriched with such manure.
