37. Spores remaining within the peridium or in the hymenial cavities

38. Basidia uniformly distrilmted through the peridium or forming skein-

39. Hymenial cavities remaining together within the peridium, their

39. Hymenial cavities (sporangioles) separating at maturity from the

40. Remaining lleshy until the maturity of the spores; no capillitium.

Setaria italica (L) Beauv. July 1-4, L. H. Pammel. 

 Hordeum vulgare L. July 14, L. H. Pammel. 

 Fagopyrum esculentum Moench. July 4, E. L. Fullmer. 

 Chclidonium majus L. June 2S, L. H. Pammel. 

 Melilotus officinalis (L.) Lam. July 13, E. L. Fullmer. 

 Verbascum blattaria L. July 4, E. L. Fullmer. 

 Galinsoga parviflora Cav. July 19, L. H. Pammel. 



These plants with the exception of Chelidonium majus were 

 collected at or near the resort and were probably introdticcd in 

 grass seed or in packing material. A single plant of Chelidonium 

 majus was found on the bay .side about one half mile from the 

 resort. The seed from which this plant grew may have been 

 carried by a bird or it may ha\'c been carried across the Bay on 

 drift material.
