txiv hmab txiv ntoo txhua xyoo, nyob rau hauv daim ntawv ntawm convex sessile caps ntawm daim duab peb sab, ib leeg los yog fused nrog ib leeg, semicircular los yog raum-puab, mus txog 12 cm ntev thiab mus txog rau 8 cm dav, nrog ib tug ntse, qee zaum me ntsis wavy ntug; pib dawb los yog dawb, tom qab yellowish los yog brownish, feem ntau nrog tsaus dots; Qhov saum npoo yog pib softly velvety, tom qab liab qab, nyob rau hauv lub hnub nyoog laus npog nrog wrinkled daim tawv nqaij. Qee zaum muaj daim ntawv prostrate kiag li.
Hymenophore tubular, dawb, me ntsis yellowing nrog lub hnub nyoog thiab thaum ziab, xyaum tsis hloov xim nyob rau hauv qhov chaw ntawm kev puas tsuaj. Tubules txog li 8 hli ntev, pores los ntawm puag ncig los yog angular mus rau elongated thiab txawm labyrinthine, nyias-walled, 3-5 ib hli.
spore luam tawm dawb.
Pulp dawb, mos, ntom, fleshy thiab watery thaum tshiab, tawv, me ntsis fibrous thiab nkig thaum qhuav, muaj ntxhiab (qee zaum tsis muaj qab ntxiag qaub-qab zib tsw), tsis muaj suab nrov lossis nrog me ntsis iab.
Microscopic kos npe:
Spores 4-5 x 1.5-2 µm, du, cylindrical los yog allantoid (me ntsis nkhaus, sausage-puab), non-amyloid, hyaline hauv KOH. Cystids tsis tuaj, tab sis spindle-shaped cystidiols tam sim no. Lub hyphal system yog dimitic.
Kev siv tshuaj lom neeg:
Cov tshuaj tiv thaiv nrog KOH ntawm qhov chaw ntawm lub hau thiab ntaub yog qhov tsis zoo.

Nceb inedible.
Daus-dawb thyromyces yog sab nraud zoo ib yam li lwm yam dawb thyromycetoid tinder fungi, feem ntau rau cov neeg sawv cev dawb ntawm genera Tyromyces thiab Postia (Oligoporus). Qhov kawg ua rau xim av rot ntawm ntoo, tsis dawb. Nws yog qhov txawv los ntawm tuab, daim duab peb sab-section caps, thiab hauv lub xeev qhuav los ntawm cov tawv nqaij daj thiab cov nqaij tawv tawv heev - thiab los ntawm cov cim microscopic.
