Observation 27999: Lentinus tigrinus var. squamosus
When: 2009-09-19
No herbarium specimen
0 Sequences

Found this growing on large old dead logs in the bottomland of Mingo National Wildlife Refuge (Swamp) during a MOMS Foray. We were fortunate enough to have Dr. Walt Sundberg along who gave us all a nice lesson about this species. Note the gills which have a growth that covers them. Walt explained that this environmentally-induced phenomenon occurs in this species in swampy areas. I’ll post pix with (L. tigrinis var squamosus or Lentodium squamulosum Morgan) and without (L. tigrinis) that growth. Thanks Walt! And if you get the chance to attend his Microscopy class at NAMA in Louisiana this year during the few days before Thanksgiving, don’t miss it.

I found another MO observation. Here is a note from the finder,
who would like a specimen if you saved any:

Summary: Wanted: Alive

Hi Dan,
That is a nice photo of the “secotioid” form of Lentinus tigrinus. It is a naturally-occuring developmental mutant of the typical agaricoid form of this species. It is fascinating because, as Tom Volk says, it looks like an evolutionary intermediate between a hymenomycete and a gasteromycete. I did some work on this years ago (I am a mycologist) and have been wanting to get back to it for some time. If you (or any other MO participant) find this again, I would be grateful to receive some fresh material for culturing—I’ll pay for the express shipping. Here’s my lab website for contact information, etc: http://www.clarku.edu/faculty/dhibbett/
