Heliogaster Orihara & K. Iwase, in Orihara et al., Mycologia 102(1): 112 (2010)

 

Etymology. Greek, ‘‘helios’’ refers to the characteristic morphology of the basidiospores reminiscent of the symbol of the sun god, and Greek, ‘‘gaster’’ refers to the basidiomal shape.

Basidiomata secotioid to gasteroid, hypogeous to subepigeous, soft, often with rudimentary stipe at the base. Gleba nonpulverulent, whitish, usually discolored when exposed to air, with irregular-shaped, empty, nonglutinous locules. Columella mostly present, more or less dendroid. Basidiospores dextrinoid, thick-walled, with large, conical to pyramidal, more or less striate, spiny ornamentation; ornamentation consisting of more or less continuous exosporium with cavities; perisporium and ectosporium present, hyaline. Basidia clavate to cylindro-clavate, 2-, 3- or 4- spored. Hymenial layer developed, forming glebal locules. Peridium of thin-walled, noninflated filamentous hyphae. Clamp connections absent in all tissues.
