Statioiies. Ad terrain humosam muscosque locis apricis 

 subapricisque in rupibus et saxis, ad terram humosam muscosam- 

 que, aut rarius etiam ad terram nudam arenosam, in silvis siccis 

 rarioribus praesertimque piniferis et in campis apricis. 



Oonidia in t hallo primario zonam continuam infra stra- 

 tmn corticale formantia, globosa, diametro circiter 0,oo8— 0,oi6 

 millim., membrana tenui, circiter 0,ooo5— 0,ooi millim. crassa, in 

 podetiis maculas majores minoresve infra stratmn corticale et 

 glomerulos sparsos, hyphis obductos, in parte extcriore et inter- 

 dum etiam in parte interiore strati medullaris myelohyphici for- 

 mantia. 



Obs. 1. Formae, supra indicatae, hujus speciei valde in- 

 constantes et distincte polyphyleticae sunt, ex iisdem podetiis na- 

 scentes, et saepe in eodem caespite, cujus podetia ejusdem origi- 

 nis sunt, provenientes. Lusus intermedii earum fere aeque nu- 

 merosi sunt, quam lusi typici, quare hae formae bene limitari 

 non possunt, et veras formas systematicas vix constituunt. 



Obs. 2. Ad formas supra indicatas et ad earum lusos in- 

 termedios etiam sequentes pertinent:
