A Synopsis of Plant Fliyla 35 



Order Auric ulariales. Reduced and degraded Basidiospo- 

 reac, related to the families of the Hynicnomyccialcs ; basidia di- 

 vided by transverse partitions. 



Family 132. Auriculariaceae. Hymenium exposed; spore- 

 fruits from irregular foliose to loose and vague aggregations of 

 basidia; more or less gelatmous. Platygloca, Anricnlana. (Pf. 

 I, I*-; 83.) 



Family 133. Pilacraceae. Spore-fruits capitate, stalked, closed, 

 filled with basidia. Pilacrc, Pilacrclla. ( Pf. I, i**, 86.) 



Order Tremellales. Reduced and degraded Basidiosporcac 

 related to the families of the Hyiiuiioiiiycctalcs ; basidia divided 

 by vertical partitions. 



Family 134. Sirobasidiaceae. Spore-fruits gelatinous, open, 

 the basidia in serial rows, spores sessile. Sirobasidiiiin. (Pf. I, 

 I**, 89.) 



Family 135. Tremellaceae. Spore-fruits gelatinous, open, ex- 

 panded to foliose and cup-shaped ; basidia collateral, elongated. 

 Exidia, TrcmcUa. ( Pf. I, i*"^, 90.) 



Family 136. Hyaloriaceae. Spore-fruits capitate, stalked, 

 closed, the basidia developed in a circular subterminal zone. Hy- 

 aloria. (Pf. I, i*'', 95.) 



FUNGI IMPERFECTI. Here are collected from 10.000 to 

 12,000 species of fungi with regard to which our knowledge is 

 quite imperfect. We do not know their ascigerous states, if in- 

 deed they have any, but it is generally assumed that they are the 

 conidial states of Ascosporcac, and that possibly in some cases 

 they have lost all else through excessive degeneration. For the 

 present they must be grouped here, and treated as though they 

 were autonomous. They are mostly parasitic. 



Order SpHAERorsiDALES. Conidia developed in pycnidia. i. e. 

 perithecium-like *' fruits."' 



Family 137. Sphaerioidaceae. Pycnidia more or less spher- 

 ical, cuticular, leathery or carbonaceous, black. PhyUosticta, 

 Phoma, SpJiacropsis, Ascochvta. Darluca, Diplodia, Scptoria.
