First records of Hygrophoraceae from Panama including a new species of Camarophyllus and a new veiled species in Hygrocybe section Firmae

Abstract

Six species of Hygrophoraceae were collected on Barro Colorado Island, representing the first fully documented records for the family from Panama. A species with a pink pileus and stipe, a glutinous partial veil, and dimorphic spores and basidia, Hygrocybe roseopallida Lodge & Ovrebo sp. nov. is described in H. section Firmae from Panama, and a more strongly pigmented form is also reported from Costa Rica. Hyphae of the outer veil are connected to the appendiculate pileipellis margin while those of the inner veil emanate from the lamellar edge. Partial veils have not been previously reported in Hygrocybe s.s. (i.e., excluding Camarophyllus). Additionally, four other species of H. section Firmae are newly reported here from Panama: Hygrocybe batistae, H. hypohaemacta, H. chloochlora and H. cf. earlei. The latter species differs from the type of H. earlei by having a white stipe and larger spore Q. Finally, we describe a second new species, Camarophyllus panamensis Lodge & Ovrebo sp. nov., which resembles C. ferrugineoalbus (Singer) Singer, but differs in having an orange stipe and much larger spores.
