Description:Albatrellus subrubescens (Murr.) Pouz., Ceska Mykol. 26:196, 1972. - Scutiger subrubescens Murr., Bull. Torrey Bot. Club 67:277, 1940. - Albatrellus similis Pouz., Folia Geobot. Phytotaxon. 1:274-276, 1966.
Basidiocarps stipitate, single or confluent, pileus 3-7 cm in diam, upper surface pale buff, glabrous to minutely tomentose, smooth at first but becoming rugose or cracking and becoming squamulose on drying, pore surface greenish-yellow or with pale reddish-orange tints in some areas, the pores angular, 2-4 per mm, with thin dissepiments, tube layer 1-2 mm thick, separated from context by a dark layer in dried specimens, strongly decurrent, stipe central to eccentric, 2-3 cm long and 0.7-1.5 cm in diam, vinaceous to buff with pale reddish-orange or brownish-orange areas on dried specimens, minutely pubesecent, context cream-colored, drying to yellowish- buff, azonate, brittle and easily sectioned when fresh, rigid and difficult to section after drying.
Hyphal system monomitic, contextual hyphae highly variable in diam, from 2-40 µm, with frequent branching, simple-septate, readily discernible in fresh specimens but becoming collapsed and agglutinated on drying, especially the lower dark layer next to the tubes, tramal hyphae similar but smaller in diam and slightly amyloid in Melzer's reagent, becoming agglutinated on drying: gloeoplerous hyphae present.
Cystidia or other sterile hymenial elements absent.
Basidia clavate, 4-sterigmate, 24-28 x 6-7 µm, simple-septate at the base. Basidiospores 3.5-4.5 x 2.5-3.5 µm, subglobose to ovoid, usually flattened on one side, hyaline, smooth, distinctly amyloid in Melzer's reagent, with a small but prominent apiculus.
Type of rot. - Terrestrial, apparently not a wood-rotting fungus. Cultural characteristics. - Unknown.
Sexuality. - Unknown.
Substrata. - On soil in pine forests. In Arizona associated with ponderosa pine (Canfield and Gilbertson, 1971).
Distribution. In North America in the Southeast and Arizona. Also known in Europe.
