very like them, though the writer has often found it safest to 

 call them simply C. squamosa, occur in the Hudson Highlands, 

 and the Catskills where they grow very robust, up to three or 

 four inches in height. Students who would determine all the 

 possible forms in our range are referred to Dr. Evans' Mono- 

 graph and Notes, and the Robbins and Blake paper. 



25. C. delicata (Ehrh.) Floerke. (PI. 3, f. 1.) A small, pretty 

 species, on decaying logs and tops of stumps in woods, probably 

 fairly common, but overlooked because so tiny. Occurs in Frank- 

 lin Clove, N. J., and in Wawayanda Cedar Swamp, and prob- 

 ably in similar swampy woods elsewhere in our area. Repre- 

 sented in our range by f. quercina (Pers.) Vainio. 



26. C. caespiticia (Pers.) Floerke, (PI. 3., f. 5.) Fairly com- 

 mon on the ground among hardwoods, sometimes on logs, and 

 once found by the writer ten feet high on a living red maple 

 in Wawayanda Cedar Swamp. Probably overlooked because 

 of the sessile, brown apothecia, much like the color of dead 

 leaves. 



27. C. floridana Vainio. (PI. 3, f. 2.) Low, rather densely 

 branching, not common, to be looked for in open, sandy woods, 

 in the Pine Barrens and on eastern Long Island. Yellow reaction 

 with KOH is helpful in identifying it. 



28. C. apodocarpa Robbins. Common in open hardwoods, 

 often in quite large colonies; may be taken for some other Cla- 

 donia in an immature, unfruited condition, as its apothecia are 

 extremely rare. Yellow reaction with KOH on the white under- 

 sides of the rather large squamules distinguishes it. 



29. C. turgida (Ehrh.) Hoffm. (PI. 3, f. 6.) Not common. 

 F. scyphifera, with small, flat cups, reported from Green 

 Pond, N. J., by Leon W. Bowen; f. corniculata, with large 

 primary squamules and rather robust podetia, with olive-tinted 

 subulate tipped branches, reported in Connecticut by Evans; 

 occurs in Adirondacks and may be looked for in Hudson High- 

 lands or Catskills. 



30. C. mitrula Tuck. (PI. 3, f. 3.) On earth in old fields, 

 woods, and banks along old woodroads, fairly common through- 

 out our area, except in higher Catskills. The usual form is f. 

 imbricatula (Nyl.) Vain., with large brown apothecia, wider 

 than the diameter of the podetia; with it sometimes occurs f. 

 pallida Robbins, with flesh colored apothecia; also f. MICRO-
