Observation 5793: Lentinus bertieri (Fr.) Fr.
When: 2007-12-26
Herbarium specimen reported
0 Sequences

small mushroom on tamarind stump (Tamarindus indica), solitary
ST: 20×2-2.5mm, central, straight, even to slightly clubbed, fuzzy like cap at base becoming less so near top
CAP: 20mm wide, depressed, strongly inrolled, extremely fuzzy (hairs 2mm long and very dense), rich deep brown, almost smooth and blackish in center
FLESH: v thin, light brown
GILL: decur, light brown, turns into pores/reticulation on stem, somewhat close, 1.5mm deep

Yet another small mushroom I’ve failed to get a spore print off of.

I had considered Lentinus briefly (I should have mentioned the erose gill margins), but ruled it out based on the reticulation where the gills meet the stalk (the photo shows it well). I don’t see this feature in the one reported by Ron Pastorino in Texas.

this thing is a total deadringer for L. bertieri, gill color and all. Others are proving to be a bit hairier… metaphorically speaking.

Happy to be of help :)

Nicely done!

Lovely to get to the bottom of this thing. Pretty common in the Florida Keys. (Although that might just be because the fruiting bodies last forever in that dry climate…) Thanks, Danny.

I’ve just gotten my first look at Pegler’s 1983 monograph. According to him, L. crinitus is restricted to tropical America, its margin is “inflexed but not involute or only slightly so,” and its pileal surface is described as “closely radially striate to strigose, not distinctly squamose, sun glabrescent and silky shining in the centre…”.

Here’s M.J. Berkley’s 1851 illustration of the type specimen (referred to by Pegler in his L. crinitus comments):

figs. 1a, 1b, 1c & 1d.


A man after my own heart, Pegler laments the “almost universal tendency to regard L. crinitus as a single, highly polymorphic species, ranging from forms with a densely villose pileus, forms with a squamose pileus, to forms with a glabrous pileus…” It seems that, among other characters, the patchy baldness of the true L. crinitus plus its pronounced striations should easily set it apart. What that makes the oodles of other Lentinus on MO, erroneously IDed as L. crinitus simply for being some degree of “hairy,” is another matter altogether.

consensus confusion

L. crinitus still wins here because CureCat’s vote for the misspelt L. crinitis is internally counted toward L. crinitus.

Lentinus critterus!

It looks like Lentinus crinitus rather than Paxillus to me. Any thoughts?
