Radiila obconica and Riccardia sinitata before ; both are rather un- 

 common. Loplwcolca heterophylla showed abundant sporophytes, 

 while PtiUdUini ptilcherrimuni had open capsules fuzzy with brown 

 spores and elaters. In Conacephcdwn conicitm the female receptacles 

 extended up several inches, while Marchantia polyniorpJia, asso- 

 ciated with Riccardia and Sphagnum, showed very numerous male 

 receptacles and very few of their feminine counterparts. In Reboulia 

 heniisplicrica, which grows abundantly close to the Falls, the recep- 

 tacles were just developing. The bases of the trees in a swamp north 

 of the Falls are especially favorable for the growth of Thelia Jiirtella, 

 and this moss was dotted with sporophytes showing the immaculate 

 white peristomes. Dicranwn jidvum (in "fruit"), D. scopariiim, and 

 D. nndulatum were all growing close together. 



The warm days of recent weeks were reflected in the flowering 

 of some of the seed plants, so that the Shadbush was well along; 

 the Gold Thread, Coptis trijoUa, added a touch of color to the 

 marshes with its greenish white flowers ; while the Fringed Milk- 

 wort, Polygala paucijolia, showed buds that were nearly open and 

 in a few instances flowers that had actually expanded. It is of course 

 difficult to make comparisons in phenology even from written 

 records, but most of us felt that these flowering plants wxre dis- 

 tinctly farther along than they were at the time of the trip of last 

 year, which was held on April 28. Apparently w-e are getting back 

 to the warm, dry part of our climatic cycle.

Trip of May 4, 1941, to Chester, N. Y. 



This trip was originally scheduled to visit the colony of Cetraria 

 islandica on Hogencamp Mountain in Palisades Interstate Park 

 near Arden, N. Y. Due to the fire hazard, however, the Governor 

 had declared all state parks closed. A group of twelve members and 

 friends turned up at the Arden station so the group went by auto- 

 mobile to a region near Chester, Orange County, N. Y., where Mr. 

 G. G. Nearing had previously collected lichens. 



Here, on Goat Hill, an outcropping of calcareous shale yielded 

 a number of crustose lichens which were collected for further 

 study. Species such as Acarospora fiiscafa, Rhizocarpon petraemn 

 var. conjcrvoides, and Urccolaria scntposa were common. A yellow,
