When: 2008-06-10

Collection location: Big Thicket National Preserve, Polk Co., Texas, USA [Click for map]

Who: Ron Pastorino (Ronpast)

Specimen available

Found in the aptly named Big Sandy Creek Unit of the Big Thicket growing on buried wood and a sclerotium which can be seen in some of the photos. Most everything seems to match the descriptions if not the photos in the references. Lots of sand on the specimens which I should have brushed off more completely.
This species has undergone several name changes in a relatively short time….Lentinus siparius to Panus siparius to Lentinus tephroleucus.

but another/newer/simpler reference for section-level treatment of Panus and Lentinus is still beyond our reach. word has it the Hibbett lab seeks to remedy this with a molecular revival of Lentinus research. there’s also this elusive text..:


it is reportedly available via ProQuest, the successor to University Microfilms.

I dunno about the current name on these…

but they sure are as bristly as all Texas.

I see it in your ob’s photos

so going through the last comment’s steps won’t be necessary, but it’s a good tool to have on hand for general use.

that photograph looks a lot like things I’ve casually called and heard called L. velutinus. I don’t have the monograph in front of me at the moment. I’ll come back to this when I get home.

5. Paste the image url in between exclamation marks anywhere on MO, like so:

this link has spaces between the !s to show the syntax:

to the comments but I did take a photo of the Bessette photo and added it to my group.

Thanks, Ron

I see the description, but Google has kindly blocked the corresponding images. Bessette’s measurements definitely conflict with Pegler’s. No idea who’s “right.” If feasible, you might consider uploading Bassette’s color plate(s).

The description in the Bessette book says
By: Ron Pastorino (Ronpast)

that the stipe can be 1.5-12mm thick.
If you google Lentinus tephroleucus + Bessette, the description will come up from that book.

included this in his sect. Velutini of Lentinus subg. Panus, meaning it ought to have a velutinous stem. sadly, yours are all covered with sand! they also appear to far exceed Pegler’s stipe width limitations of 4mm. I’m curious what your two books’ entries for L. tephroleucus look like…

Another cool Texas Lentinus!
