Family 17. MONASCACEAE 

 Schroeter 148 



Mycelium typically well developed, branched and septate, saprophytic, forming 

 conidia; asci sporangium-like, terminal, with an individual hyphal wall; spores many, 

 hyaline to brown. 



Spores many; asci enclosed by interwoven hyphae Monascus S 148 



Family 18. GYMNASCACEAE 



8:820, 10:70, 11:437, 14:824, 16:805, 18:195, 24:1145 



Mycelium more or less well developed, branched and septate, usually sapro- 

 phytic, frequently forming conidia; asci grouped, more rarely scattered, in a more 

 or less regular globoid mycelial weft, sometimes dense and differentiated externally 

 into a rudimentary peridium; asci globose to saccate, typically 8-spored, rarely 

 2-many-spored; spores typically 1-celled and hyaline. 



The weft-like ascoma is typical of this family, but it passes gradually into the 

 denser type with rudimentary peridium, distinguishable with difficulty, if at all, from 

 the fruit-body of such genera of the Myriangiaceae as Elsinoe and Plectodiscella. 

 Penicillium and Penicilliopsis have been included in the Eurotiaceae (Aspergillaceae) 

 by Fischer, but the latter are here regarded as comprising perithecial forms only.
