I agree Phil.

Photo #1 appears to well support the claim that the gills are truly forked. Thanks for pointing this out.

Dave, enlarge photo #1 and follow the dichotomus branching to the margin. Does not look like lamellulae to me.

Are the gills truly forked?

Or is it that the lamellulae terminate very close to the longer gills?

I have IDed specimens of P. dryinus which showed little, if any, evidence of a partial veil. I’m certainly not saying this is P. dryinus, but maybe some related tropical species…?

thanks for the explanation.

P.dryinus has a fugacious ring and “frosted” cap. Lentinus levis has a very hairy stem. Both are common summer and fall in the Northeast and Lake States.

From Univ. of Tenn. http://www.bio.utk.edu/...:

“Separation from P. dryinus is difficult, but P. levis seems to be a summer fungus (and subtropical to tropical), while P. dryinus is a fall to early winter fungus more common in northwest United States and adjacent Canada.”

Lentinus levis
By: walt sturgeon (Mycowalt)

is not tropical to subtropical in distribution.

I was referring to L. levis being a look-alike to Pleurotus dryinus and definately not proposing it as an Id. for this obs!.

Hi Walt

I’ve never seen L. levis—just going by macro description and the fact that it is tropical to sub tropical in distribution. To Phil’s point do the forked gills help narrow it down?


Lentinus levis
By: walt sturgeon (Mycowalt)

is common in Northern Ohio and this obs. is not even remotely similar.

L. levis
By: Phil Yeager (gunchky)
2014-05-07 19:42:19 CDT (-0400)

is aka Panus strigosus. I still believe the key to deciphering this species are the gills. How many genera have these particular features?

Lentinus sp.
By: Susanne Sourell (suse)

Yes, definitely no partial veil and distinct ring on the stem. According to the ‘Catalogo de plantas e fungos do Brasil’ there are 12 species of Lentinus in Brazil, but neither L. sajor-caju nor L. levis is listed.

L. sajor-caju has a partial veil and distinct ring on the stem which I don’t see on this obs.

Learned a new one today!

This obs reminded me of P. dryinus too though it lacks the densely hairy cap, partial veil and yellow staining of P. dryinus. According to M. Kuo Lentinus levis (aka Pleurotus levis) is a look alike that appears in warm climates.


Did some research

but have not found any Pleurotus species with this particular pattern of gill branching.

I see

Sharp Dichotomously branched gills with what lookss like a floccose margin and a depressed disc with slight discolorations. Photo reminds me of Pleurotus dryinus, but I have never id one and don’t know if they are in your geographical location. Looking forward to your solution.
