further reduced to 4 or 2 in N. Nmjpuyi) . The same fiagellar appendage is also 

 present but usually shorter (Fig-. 17). 



Two other little known genera may either beh)ng here or in the next family. 

 In (Joccidiascus mycelium is absent, the asci develop following isogamous copu- 

 lation, and the spore number is fixed at 8 (Fig. 13, 2). This species has been 

 found in the digestive tract of Brosophila but has not been cultivated. In Mono- 

 sporella both mycelium and copulation are absent. The ascus produces a single 

 acicular spore parthenogenetically (Fig. 13, 3). The members of this genus 

 have also been found in the digestive tract of invertebrates and not cultivated.

Fries, Syst. Orb. Veg. 306, 1825, published a new genus Trichosporum which 

 is spelled Tn'chosponum in the index. No species was attributed to this genus 

 at the time. I can find no mention of the genus in his Sy.stema mycologicum
