TYLOSTOMATACEAE 157 



granulosum represented in D. Saccardo's Mycotheca italica, No. 424, and find them 

 to be smaller and smoother than those of the American plant. In one plant (Path. 

 & Myc. Herb.) the spores are spherical to slightly irregular, smooth or nearly so, 

 3.7 4.4/u thick; in the specimen at the New York Botanical Garden the spores are 

 spherical to oval. 3.7-4.2p thick or if oval up to 5.5/i long. 



The southern representative of T. campestre has been named T. Berkeleyii by Lloyd, 

 and while the differences are not great we are retaining the name (see that species for 

 comparison). Lloyd is right in considering T. punctatitm Pk. only a form of T. cam- 

 pesire. A part of the type collection at the New York Botanical Garden, noted below, 

 is similar and with identical spores, minutely roughened, 5-6.5/1 thick.

 Colorado. Harkness, coll. (N. Y. Bot. Gard. Herb., as T. fimbrialum) . Spores nearly spherical, 



minutely warted with elongated warts, 5— 7.2/x thick. Capillitium threads septate, swollen 



at the joints, usually up to about 6/x thick, up to 8m or 9ji at the joints: walls irregularly 



thickened, closing the lumen in places.

Tylostoma Berkeleyii Lloyd 



Plates 83 and 119 



Spore case subglobose, 1—1.7 cm. thick; outer peridium as in T. campestre, wearing 

 away slowly but with traces nearly always remaining as small, inherent flecks on the 

 grayish to ochraceous tan inner peridium; the basal portion persistent as a closely 

 applied, sandy cup. Mouth as in T. campestre. Stem about 2.5-3 cm. long, rather 

 slender, with a deep brown spongy or flaky superficial layer, not so scaly as in T. cam- 

 pestre, apparently smooth in No. 8707 from Porto Rico, sulcate when dry, base with a 

 small bulb. 



Spores (of plant from Folly Island, S. C.) spherical to oval, distinctly warted and 

 partially reticulated, 4.5-6/n thick or if oval up to 7.2^ long. Capillitium sparingly 

 septate, swollen at the joints, branched, irregular, 4-9/u thick, larger at the swollen 

 joints. 



This is the southern representative of T. campestre. The spores of the present 

 species differ only in having slightly more prominent warts which are distinctly more 

 elongated so as to form a partial reticulum. The stem is less scaly (in plants seen); 

 there is more color in the denuded inner peridium, and the size averages smaller.
