Order 5. DACRYOMYCETALES. 



This order is quite closely allied to the last in habit, but differs 

 in the undivided basidia which allv it more closelv with the 



J * 



higher forms of Agaricales. The species are mostly small and 

 comparatively inconspicuous, some are flat and effused, others 

 are elongate and resemble flattened clubs. 



The American genera may be distinguished as follows : 



1. Sessile, depressed or resupinate. 2. 

 Elongate or with a distinct stipe. 4. 



2. Mould-like with a waxy smoothish hymenium. ARRHYTIDIA. 

 Thin, forming a waxy effused crust. CERACEA. 

 Cushion-shaped or globular, gelatinous. 3- 



3. Conidia globular. HoRMOMYCES. 

 Conidia elliptic. DACRYOMYCES. 



4. Hymenium covering only a portion of the fungus. 5- 

 Hymeniurn extending to all parts of the fungus. 6. 



5. Cartilaginous or fleshy, capitate. DITIOLA. 

 Gelatinous or fleshy when dry, spatulate or goblet-shaped. GUF.PINIA. 



6. Capitate ; spores ultimately septate. DACRYOPSIS. 

 Capitate ; spores simple, one on each basidium. COLLYRIA. 

 Awl-shaped, simple or branched. CALOCERA. 



The species of Calocera resemble small species of the club 

 fungi (Clavaria). Guepinia has a common yellow species that 

 grows in the cracks of rails and logs, forming slender spatulate 

 forms a half an inch or more high. Like the members of the 

 preceding order, the species are poorly known.
