Observation 131613: Polyporales sensu lato

When: 2013-04-06

Collection location: Otsego Co. New York, USA [Click for map]

Who: Phil Yeager (gunchky)

Specimen available

Effuse-reflexed fungus on dead haardwood. Caps white, turgid, soft on top with a cottony feel. Caps 10-35mm long x6-17mm wide x6-10mm thick. Pores minute, and becoming tooth-like near some of the decurved margins. THe effused section is 1-4mm thick, and the mycelial base is like a cottony cobweb. The total lenght of this specimen is approx. 21cm long. KOH on pores and cap, light yellowish. Same reaction wih Ammonia and Iron Sulfate on cap and pores, but iron sulfate produces more vivid color on the cap. Don’t know if this should happen, or maybe my chemicals are getting too old. Any opinions? Specimen still spongy after three days inside.

I’ll do some more research on Skeletocutis.

Why eliminate Skeletocutis?

Skeletocutis nivea grows on hardwoods exclusively. Not sure if this is also in America. But I’m sure there are others too.
But it really sounds more like Oligoporus or Tyromyces.
Micro photos would help.

Skeletocutis, because this was found on deciduous wood.

are filamentous and minute, about ten per mm. Cuticle peels easily, is soft, rubbery, and tears easily. Thought it may have been Tyromyces chioneus, but that species grows solitary or in groups. Doesn’t mention fused or resupinate in my literature. No soapy taste, but it is like chewing a leathery substance. Still working on it.

Oligoporus/Postia/Tyromyces. Or Skeletocutis.
