that he could be dragged to even the most informal social affairs by his family. 

 He derived the keenest pleasure from his botanical correspondence and seemed 

 to feel his lichen friendships were a haven and refuge from all the sordid and 

 petty insincerities of common day dealings. He detested "bluff " and insincerity 

 and was very quick to detect the hypocrisies of ordinary social intercourse. 

 The old soldiers cherished a warm affection for him — "the old Dutch Doc" — 

 feeling sure of his absolute sincerity in caring for their interests. How keenly 

 the city of Santa Monica felt the loss of their old doctor' was beautifully shown 

 on the day of his funeral by the lowering of the city flag to half mast in his mem- 

 ory. This tribute is the more interesting when it is borne in mind that Dr. 

 Hasse had practically no conception of "politics," and had never been "prom- 

 inent" in the usually accepted meaning of this word. It was an unlooked for 

 tribute to his quarter century of being a good neighbor in the fullest sense. 



Possibly the only papers ever written by Dr. Hasse besides his "The Lichen 

 Flora of Southern California " are his articles in the Bryologist, nearly all 

 also on Southern California lichens. It is gratifying to learn that these, along 

 with other notes on the lichens of this part of California, are likely to be pub- 

 lished — possibly in the form of a supplementary bulletin. 



He became a member of the Sullivant Moss Society in 1905; in 1913 he 

 became curator of the Society's Lichen Herbarium. During the three years 

 while he was its curator 1120 additional specimens were added to the herbar- 

 ium; of this number 397 are from Southern California, collected by Doctor 

 Hasse himself. During his twenty years of lichen study Doctor Hasse discovered 

 many a new and undescribed specimen; many of them were described by himself, 

 but quite a number were named for him, and the specific name ^'hassei" can be 

 observed in a number of California specimens. Dr. Zahlbruckner further 

 honored him by naming a new genus of lichens — Hassea. 



Besides being a member of the Sullivant Moss Society he was also a member 

 of the Sierra Club and of the Southern California Academy of Sciences. 



Dr. Hasse left behind him a fine library consisting of medical and botanical 

 works, and quite a large herbarium.^ It would indeed be fortunate for Southern 

 California if this fine collection could be kept intact and retained in that part 

 of the state. The botanical works are in the main lichenological.
