Nummularia luzonensis Yates, ined.

PHILIPPINES: Luzon, Province of Tayabas, Mt. Cadig, XII.1916, Yates, H. S. 25760, bamboo culms, as Nummularia luzonensis Yates, n. sp. (GZU-Petrak 1459; K 36393).

Possibly a loculoascomycete. Miller (1961) mentioned that this fungus is close to Hypoxylon nummularioides Rehm, but has a hyaline sheath surrounding the ascospore. Despite the similarities in the stromatal morphology and ascospore shape, Hypoxylon nummularioides and N. luzonensis have several major differences and do not appear closely related. Nummularia luzonensis differs from H. nummularioides in lacking an ascospore germ slit, in having a thickening on the ascus tip where an apical ring is apparently lacking, and in having a thick hyaline sheath surrounding the ascospore. This fungus should be excluded from the Xylariaceae as suspected by Laessøe and Spooner (1994). It should be noted that most of the ascospores in the material of N. luzonensis have become distorted and changed in shape.
