Fleshy Fungi of New Brunswick >> Entoloma luteum

Entoloma luteum Peck

Gregarious (3) among mosses under Abies balsamea, Picea rubens and Vaccinium angustifolium, NW of Lepreau, Charlotte Co., New Brunswick. (27-08-08/05)

Basidiospores pink in spore print, cubical, 8.8-10.4 X 8.6-10.2 μm, D/d = 1.00-1.05 (average[12]: 9.7 X 9.2 μm, D/d = 1.05). Cheilocystidia forming a continuous sterile margin, clavate, with clamp connections. Pileipellis a cutis composed of hyphae with cytoplasmic pigments

Similar to Entoloma quadratum and E. murrayi, E. luteum is recognized by its smoky yellow brown rather than bright orange or yellow pileus. It is less common than E. quadratum but has a North American range extending from Newfoundland down the Appalachian ranges all the way to North Carolina and Tennessee. Maps on MycoPortal also show it occurring in the Great Lakes area of the United States, although there seem to be fewer records from this region.

Collection 27-08-08/05 is a good fit for Hesler's (Entoloma in Southeastern North America, J. Cramer, 1967) description of a collection from Tennessee. Although Hesler stated that his material lacked clamp connections, it is possible these were scattered and simply overlooked.
