Family 45. CALICIACEAE 

 Rehm 388, Zahlbruckner 95 (80) 



Mycelium inconspicuous and saprophytic, or parasitic on algae, forming a 

 powdery, crustose, foliose or fruticose thallus; apothecia sessile or stalked, cup- to 

 top-shaped, opening more or less completely, asci disappearing very early and the 

 disk then covered with a persistent mass of spores and paraphyses. i.e. a mazaedium; 

 exciple prosenchymic, horny, proper or thalline. 



A. Mycelium saprophytic, at least not forming a 



thallus 



1. Spores 1-cclled, globose or globoid, rarely ellip- 



soid 



a. Spores hyaline or subhyalinc 



(1) Algae present but not forming a thallus 



(2) Algae lacking 



b. Spores dark or at least brownish 



(1) Spores globoid, smooth, dark 



(a) Apothecia black, nearly sessile 



(b) Apothecia bright-colored, with a slender 



stalk 



(2) Spores ellipsoid, reticulate, brownish; apo- 



thecia nearly sessile 



2. Spores typically 2-x-celled 



a. Spores 2-celled 



(1) Apothecia sessile 



(2) Apothecia with a slender stalk 



b. Spores x-celled 



B. Mycelium forming a thallus with algae 

 1. Thallus crustose 



a. Spores 1-celled, typically globose to globoid
