Tieghemiomyces

TIEGHEMIOMYCES R.K. Benjamin, 1959 (Aliso 4:390).

Sporangiophores erect, unbranched or branched, bearing fertile hyphae laterally. Fertile hyphae septate, branched subverticellately, bearing many multicelled fertile branches bearing 2-spored merosporangia. Sporangiospores subglobose to ellipsoid; dry at maturity. Zygospores globose, wall thin and ornamented; suspensors hyphoid. Haustorial parasites of Mucorales.

Type species: T. californicus.

Species of Tieghemiomyces:
T. californicus R.K. Benjamin, 1959 (Aliso 4:390).
T. parasiticus R.K. Benjamin, 1961 (Aliso 5:11).

Benjamin (1959) reported that T. californicus could be grown on many culture media on numerous mucoralean hosts. He also said that T. californicus could be grown on MEYE agar without a host and it would reproduce normally, both sexually and asexually. Sporangiophores of mature T. californicus separate readily at a zone immediately below the spore-forming region. A second species, T. parasiticus, was isolated from mouse dung collected in Illinois (Benjamin, 1961).
