Fructificationes circiter 1 mm. diametro, gregariae, erumpentes, haud confluentes, convexae, genus Peziculam in mentem referentes, margine libero, haud incurvo, infra brunneo. Hymenium convexum, pruinatum, ex alutaceo roseo-cinnamomeum. Basidia juvenilia clavata, intus granulata, 75-80(-200) x 12-16 µ. Paraphyses (acanthophyses) elongatae, supra vix incrassatae, apice aculeatae, 4-6 µ diametro. Sporae non visae. Hyphae hyalinae, dense intertextae, vix distinguendae, crasse tunicatae, non nodosae, 4-4.5 µ diametro, accretionibus mineralibus magnis subglobosis intermixtis.

In habit the species recalls A. Farlowii Burt and A. Grantii Lloyd. From the former it differs in the more slender paraphyses, aculeate only at the apex, and from the latter in the microscopic characters, in so far as they were indicated by the author. The flesh is remarkably firm for the genus and the elements difficult to distinguish. Scattered throughout the subhymenial tissue are large globose clusters of mineral matter, reaching up to 30 µ in diameter.

Resupinatus, effusus, arcte adnatus, tenuis, mollis, circiter 10 cm. longus, 1-2 cm. latus, margine indeterminato aurantiaco. Hymenium miniatum, poroso-reticulatum, sicco facile e subiculo separandum. Contextus 140-160 µ crassus, ex hyphis hyalinis, 2-4 µ diametro, tenuiter tunicatis, non nodoso-septatis, laxe intertextis, compositus. Basidia clavata, 4-sterigmatica, 15-18 x 5 µ. Sporae hyalinae, allantoideae, 5-6 x 1-1.5 µ. Gloeocystidia cylindrica vel fusiformia, 40-60 x 5-7 µ, tenuiter tunicata, succo rubido repleta, e plicis ad 20 µ emergentia.

In general appearance this species recalls Poria taxicola (Pers.) Bres. and Merulius Ravenelii, but the colour is brighter than in either. From Poria taxicola it differs in the narrower basal hyphae and from M. Ravenelii in the presence of thin-walled gloeocystidia, with coloured contents, on the folds of the hymenium.
