I cannot endorse your eating of any mushroom whose identity is uncertain. Yours appear to lack the purple present in the photos linked earlier, but other images of P. radicata (if they are, in fact, P. radicata) also lack those purple tones. Seeing as the description at MycoBank:


makes no mention of purple at all, the specimens in the InBio photo are likely either a Costa Rican color variant or some other species. I would compare microcharacters with that description if you’re intent on confirming this ID.

Also, “as good as European truffles” sounds pretty overhyped. Still, I wouldn’t mind sampling these sometime to see how they stack up.

Estas dos ultimas fotos muestran alguna coloracion parecida, Danny, en tu opinion es la misma especie.? Me refiero a que el tenquique tiene fama de ser equivalente a la trufa europea en sabor, y si es seguro comerlo..?

compare with:


(labelled Fistulina radicata)

lots more purple in these Costa Rican specimens.

Yes, agree. P.radicara was reported in Panama, but if this specimen not is P. radicata is maybe a new Pseudofistulina species, and I cant do the taxonomic work. Another thing that may we use as specie characteristic is an apparent symbiosis with tree species, the P. radicata was reported only in Quercus family, but this specimen grows only in Cassia (Fabaceae) roots.

also a possiblity

and a better match with this hymenium. A. peckianus (as written below) has angular pores. however…

Its [P. radicata’s] distinguishing features, aside from the separated tubes, include its velvety brownish cap surface, its long and rooting stem, and the peculiar way the white pore surface terminates abruptly at the apex of the stem.

these pores/tubes are Merismodes-like, clustered and densly hairy, not separated, not smooth. the termination of the hymenium doesn´t look terribly “abrupt” either…

very promising indeed.

definitely not a perfect match, but a start.

Albatrellus peckianus

Description: Fruitbody multipileate and multiseptate, branched and petaloid, no more than 7 cm wide, up to 10 cm tall; surface squamulose-scaly, brownish yellow on disc, yellow toward margin, white at margin. Context: thin, white. Pleasant odor with strongly fungal taste. Hymenophore: with minute angular pores, white. Spore print white.

Growth habit: Solitary to gregarious.
Habitat: Soil, possibly from buried wood in oak forests.
Season: Throughout rainy season.
Uses: Poisonous.
Distribution: Western North America, Costa Rica, Japan. In Costa Rica in Central Pacific Conservation Area (San Gerardo de Dota).
Observations: Identifiable by the multipileate shape from a common stipe, many petaloid pilei, yellow above and white below.

At least it’s a record that the Albatrellaceae is represented in the region.

But I think it is something different though.

has databases for the following countries in the region:

Fungi of Brazil
Fungi of Chile
Fungi of Cuba
Fungi of the Dominican Republic
Fungi of Puerto Rico
Fungi of Trinidad & Tobago
Fungi of Venezuela

There’s no telling how up to date any of them are, but none has any entries under either Albatrellus or Scutiger, nor is either genus present in Dennis’ Fungus Flora of Venezuela and Adjacent Countries.

Are there Albatrellus/Scutiger species in Panama?

Or something in that vein? This find looks a lot like one of them especially the northern hemisphere S. pes-caprae.

Associated to live Cassia roots. May be inmature..
