Remarks (internal):The spores consistently exhibit pedicels that vary in length as the fungus matures; however, climatic conditions may also play a role in the variation observed. The Chihuahuan spores typically have pedicels that are approximately 2 µm long, although longer (? 4 µm) pedicels were also observed. Comparison of the type specimens of Disciseda hyalothrix and D. pedicellata by Moreno et al. (2003) concluded that these species are conspecific. Laferriére & Gilbertson (1992) were the first to report D. hyalothrix from Chihuahua.

Observations - In Mexico, D. hyalothrix has previously been reported from arid zones in Baja California (Ochoa & Moreno 2006) and Sonora (Moreno et al. 2007). It is characterized by large, strongly ornamented spores [(6-) 7-8 µm in diam.] with episporial spines that are apically fused and form flat tipped processes that are easily observed under phase contrast microscopy or (more clearly) under SEM.
