Specimen examined.
UNITED STATES. New York: Hamilton County, Raquette Lake, Silver Beach Bog, Sphagnum substrate under Tsuga , Larix , 550 m, 28 Jul 1982, A. Sabol AS30 (CORT 007356).
Discussion.
This species is known only from a single basidiome collected in New York. The description is drawn from the original collection notes. It is closely related to H. subconnatum but differs from it by the smaller spore size, shorter stipe, and association with Sphagnum . It is recorded from the same locality and habitat as H. quebecense but differs from that species by ITS sequence and smaller spores. We refrain from describing the taxon as new until confirmed by additional collections and sequence data.
