This
beautiful and distinct mushroom will be treated as "Rozites caperata"
in many older field guides, but DNA studies (see below) have determined that it
is actually a Cortinarius.
The species
can be recognized by its colors; the pasted-Kleenex texture of its young cap
surface; its thick, white ring; and its rusty brown spore print.
Cortinarius
caperatus is often given the common name "Gypsy Mushroom," for
reasons I cannot discover. The species was originally named in Europe, but when
I conjure up memories of European gypsies I have seen in Portugal and Greece,
no immediate parallels come to mind.
Ecology:
Mycorrhizal with conifers, hardwoods, and bushes in the blueberry family;
growing alone or, more often, gregariously; summer and fall; widely distributed
in northern and eastern North America.
Cap: 5-15
cm; convex, becoming broadly convex, flat, or somewhat bell-shaped; dry;
usually wrinkled; when young with a grayish to whitish, Kleenex-like coating of
fibers, especially over the center; pale yellowish at first, but soon yellowish
brown, often with a pale margin.
Gills:
Attached to the stem; close; pale at first, becoming brown or cinnamon brown;
the faces sometimes somewhat mottled or striped; covered by a white partial
veil when young.
Stem: 5-13
cm long; 1-2.5 cm thick at the apex; equal or slightly swollen at the base;
dry; usually rough or shaggy near the apex; whitish or pale tan; with a thick
white ring at the midsection; sometimes with a whitish covering near the base.
Flesh:
Whitish, grayish, or pale lilac.
Odor: Not
distinctive.
Spore
Print: Rusty brown.
Microscopic
Features: Spores 10-15 x 7-10 µ; ellipsoid or nearly amygdaliform; moderately
verrucose. Cheilo- and pleurocystidia absent. Pileipellis a cutis.
"Fries
was not far wrong," wrote Alexander Smith in 1949, "when he placed
Rozites caperata in Cortinarius" (468). Since so many Friesian divisions
have been mutilated by genetic analysis, it is nice that Fries's Cortinarius
caperatus is once again the correct name for this mushroom--after going through
one (human) generation as Pholiota caperata and another generation as Rozites
caperata.
A 2002
study by Peintner and others vindicated the old Swede (for once), finding
Rozites, Cuphocybe, and Rapacia to be synonymous with Cortinarius. A subsequent
publication made the taxonomic transfers.
