Observation 4260: Parasola plicatilis (Curtis) Redhead, Vilgalys & Hopple

When: 2007-07-31

Collection location: Madison Heights, Pasadena, California, USA [Click for map]

Who: Jason Hollinger (jason)

No specimen available

Notes:
Must be either C. disseminatus or C.
plicatilis
due to the minute stature and pleated, translucent cap. I’ve watched them fruit periodically in a lawn nearby for a month or two now, and they seem completely unassociated with wood or wood debris, just scattered about the lawn. They grow scattered to at most in groups of 3 to 4, hardly what I’d call “densely gregarious” (in Arora’s words). Further, my spores are way too large for C. disseminatus. Actually, they’re too large for either species: (from Arora)

C. d. 7-10×4-5um
C. p. 10-13×6.5-10um
mine 15-16.5×12.5-13.5um

(I will admit it is tough to get a spore print off of one of these things…)

…is the correct name based on the recent (2000) breakup of Coprinus based on DNA evidence.
