PSORA CRENATA. FROM MRS. JOSEPH CLEMENS. 

 TEXAS (Fig. 1018). Determined by Prof. Bruce Fink. When I 

 first saw it I thought it was a very novel 

 fungus, but when I sectioned it I found 

 it was a lichen. I sent it to Prof. Fink, 

 who is our best authority on the lichens, 

 and he determined it as above. I 

 often receive lichens for fungi, and 

 can usually tell them at a glance, but 

 this one deceived me. It grew on the 

 bare ground, and its general resem- 

 blance to a fungus is very close. We 

 apologize to our readers for presenting 

 in "Mycological" Notes a figure of a 

 lichen, but the species may puzzle others, 

 as it puzzled me. 



IRPEX SAEPIARIA, FROM DR. J. B. CLELAND. AUSTRA- 

 LIA (Fig. 1019). Resupinate with reflexed pileus. Pileus coriaceous, 

 dark brown (Brussels) 

 smooth. Context con- 

 colorous. Teeth dense, 

 2-3 mm. long, concol- 

 orous, irregular. Hy- 

 menium white. Setae 

 densely covering the 

 teeth, projecting 20-30 

 mic. Spores globose, 5 mic., smooth. 



In Mycological Notes, page 633, we noticed a very similar plant, 

 trpex iyoensis from Japan. To the eye they are much alike, but the 

 setae characters are different. There occurs in the Handbook a 

 record of Irpex tabacinus, an American species, in Australia. The 

 probabilities are the record was based on this same plant, but Irpex 

 tabacinus, while somewhat similar, is quite different. All these 

 plants belong to a section of Irpex corresponding to "Hymenochaete." 

 There is no "generic" name for this section now, although they are 

 included with others under the generic term "Hydnochaete." We 

 considered this "genus" in Myc. Notes, page 559, but there restricted 

 it to species with granular or tubercular hymenium. 



PHYSALACRIA INFLATA, FROM REV. C. TORREND, 

 BRAZIL (Fig. 1020). We gave in Myc. Notes (old Spec. Series, 

 page 4) a full account and history of this unique 

 and rare little species. We are much pleased to 

 have it come in to us from Brazil. I believe the 

 plant has been reported from the Philippines, 

 but I have only heretofore known it from the 

 United States. 



There has been recently a species (Physalacria

rugosa) named from Brazil, which I judge from the description is the 

 same as our United States' species.
