Observation 5144: Plicatura crispa (Pers.) Rea
When: 2007-11-21
Herbarium specimen reported

Notes: small shelf fungus on small oak twig (5mm diameter)
CAP: 15mm wide, on bottom of twig, broad funnels opening downward, brown to tan, zoned, hairy, white fuzzy growing margin
FLESH: v thin (much less than 1mm), white?, toughish
GILL: irregularly conspicuously wrinkled surface, grayish maybe a bit bluish, white near margin, 3 wrinkles per mm
SPORE: didn’t yield a detectable spore print despite being fresh
The wrinkled fertile surface suggests to me Merulius or Serpula (taken from the Stereaceae key in Demystified). Darvin showed me Plicaturopsis crispa (= Trogia crispa), very compelling.

Recognized by sight: Trogia is restricted to the tropics. By molecular sequencing and morphology this species is now known to fit well within the concept of Plicatura (e.g. close to Plicatura nivea) and thus Plicaturopsis is gone. See— I’m helping to reduce the number of fungal genera. No matter what you call it, it’s a very cool fungus.
