' . /'~ This interesting little mushroom is considered a Gastromycete because it has its spores encased inside of a pouch much like the familiar and larger puftballs. In effect, the tiny eggs that one sees resting at the bottom of the small nest could be likened to minia­ ........~ . l-- ture puffballs. I personally like to refer to them as lentils or eggs. .. ... There are two generally encountered genera--Crucibu/um and Middle peece Cyathus. Crucibu/um has a shallow ''nest" which contains white Sheath eggs. Cyathus, on the other hand, has a longer and deeper nest that could be likened to an inverted bell or perhaps a vase. The "eggs" in Cyathus are black or at. least not white. They vary in deeper colors, cream, gray, black, etc. page 1 MEMBERSHIP MEETING Spore Prints Tuesday, May 11, at 7 :30 PM at the Center for Urban Horticulture, is published monthly, September through June by the 3501NE41st Street, Seattle PUGET SOUND MYCOLOGICAL SOCIETY It's May, and the height of morel season-and we are going to Center for Urban Horticulture, Box 3 54115 learn all about matsutake.
