I’ve always thought that Lentinus crinitus was the only species that looks anything like it in my part of FL… and it my be the most common mushroom here in Southwest Florida, growing on dead conifers (as well as the invasive exotic melaleuca tree).

I don’t have that monograph… but I have always gone off of James W. Kimbrough’s description and photo of L. crinitus in Common Florida Mushrooms (published in 2000)(it’s a direct quote from pg. 20):

here’s what is says in the Lentinus key:

“3. Pileus 1-4 cm in diameter, yellowish to reddish-brown, strongly striate, stipe without fibrillar annulus……. Lentinus crinitus (p. 20)”

“13 Lentinus crinitus (Linn.:Fr.)Fr. (inedible)

The pale yellowish-brown to reddish-brown pileus often with a purplish tint is 1.0-4.0cm in diameter, and covered with loose brown fascicles of brown hairs with free ends. The lammellae are deeply decurrent, slightly fusing or appearing almost poroid near the stipe, and with dentate edges. The stipe is 1.0-4.0 × 0.2-0.6 cm, scurfy, and slightly lighter in color than the pileus.

The spores are white in deposit, narrowly cylindric to allantoid, 5.5-7.0 × 1.8-2.7 µm, not turning blue in iodine. Basidia are narrowly clavate, 12.0-14.0 × 4.0-5.0 µm, with four sterigmata.

This species can be recognized from others by its pale stipe, crowded lamellae, and cap margins that are only slightly enrolled. This species is very common on decaying logs throughout Florida"(Kimbrough, pg. 20-21).

like I said below, I do in fact have multiple dried specimens (cracker dry/vacuum-sealed) and many different spore prints (done on sterile foil in front of flowhood or in SAB).

Now it’d be really cool to scope everything and come up with a different species; however, I’m pretty sure that all of my “L. crinitus” OBs are in fact L. crinitus, even despite how many look lighter/darker or big/small.

Do you want me to collect more specimens, take pics and match em, take prints, then mail you a huge collection so you can get it all together!?

I don’t have a scope… maybe a professor can help me with it at school tho.

I’d love to hear what Kimbrough has to say about all this… I wish he was on here lol.

Do you have any idea of what else they could be?

Here are some of my other “L. crinitus” OBs (mostly on pine/melaleuca):

I know I’ve posted more… but I usually ignore these because there are so many of them!!!

cheers from sunny SWFL

An exercise in Lentinus caution given the limited information in this observation. What else it could be, or even what section it might belong in, I can’t really comment on without Pegler’s monograph in front of me, and even then…

Do you have any more photos? A specimen saved?

Why do you change all of my L. crinitus OBs?

If they are not Lentinus crinitus… then what are they?

I have a few spore prints and dried specimens from many different collections in many different areas on many different substrates (and in many different months of the year)…
