Marthanella

Marthanella States & Fogel 1999, in Satest & Fogel, MYCOTAXON-ITHACA NY, 71, 423-430 (1999).

Etymology: Named in honor of Dr. Martha Christensen, mentor and distinguished American mycologist.

Diagnosis: Basidiomata hypogeous, unevenly globose to subglobose. Peridium triplex, the outer layer deciduous in age, composed of loosely interwoven, thin-walled hyaline hyphae that intergrade with thick-walled hyphae of the medial layer below. Medial layer membranous and pliant composed of compactly interwoven, thick-walled ochraceous hyphae.. Innermost layer cellular (pseudoparenchymatous) mixed with swollen hyphal elements (prosenchyma), weakly gelatinized at maturity, layers separable as a unit from the gleba. Gleba white to light gray with occasional olivaceous tints, firm and somewhat gelatinous when young becoming granular and subpulverulent but remaining intact at maturity, composed of small peridioles that when sectioned cause the gleba to appear mottled; columella and capillitium absent. Basidia ventricose and 8-spored. Spores subglobose to mostly ellipsoid, hyaline to light yellow olivaceous in mass and viewed in refracted light, with a short pedicel.
