The fungus is spread between the plants due to the spores produced in the basidiocarp. They are distinguished from other tremelloid species by the lack of a macroscopic basidiocarp. They can be differentiated by their spores and morphology of their basidiocarp. In mycology, trama is the inner, fleshy portion of a mushroom's basidiocarp, or fruit body. This basidiocarp produces basidiospores that will further infect new hosts. "H. hyalinus" specifically attaches to the basidiocarp on the sporocarp (fruiting body) of the fungus. The basidiocarp remains closed until after the spores have been released from the basidia. The basidiocarp has a leathery texture when fresh, but becomes brittle when dry.
