 line south of Black Beach Anchorage, I. Santa Maria, nos. 34-221 A

LOBOGOLAX Howe, 1914 

 Lobocolax deformans Howe 



Plants parasitic on Prionitis, on the surface forming irregular lumps 

 to 1-5 mm broad and nearly as high; structurally largely a medulla of 

 very delicate and very densely intricate filaments surrounded by a narrow 

 cortex of anticlinal sparingly branched rows of cells about 5 fx diam. near 

 the surface but a little deeper nearly 7 ix diam., appearing nearly square, 

 the outer cuticle when intact thick and lamellate. 



Howe 1914, p. 91, text-figs. 20-39, pi. 32, fig. A, pis. 64, 65 ; DeToni 

 6, p. 82; Kylin 1941, p. 13; Smith 1944, p. 247, pi. 56, fig. 3. 



The appearance of a parasite which seems identical in general features 

 to Howe's Peruvian plant, on a different species of Prionitis and in the 

 northern hemisphere, is very interesting. Unfortunately the material is 

 sterile and the identification based on vegetative characters alone. The 

 cortex was commonly lost from the material found and the exposed 

 medulla infiltrated with filamentous endophytes. The ordinal and family 

 relationships of this genus are not satisfactorily established, as DeToni 

 has pointed out. Smith's record (loc. citj, appearing while this was in 

 manuscript, carries the species still farther north, to the Monterey Penin- 

 sula, California. 



Mexico: Baja California, frequent on Prionitis filiformis at South 

 Bay, I. Cerros, no. 34-634, 10 Mar. 1934. 



Kallymeniaceae 



Plants foliaceous or divided, strap shaped, bushy; structurally the 

 medulla loosely filamentous or apparently parenchymatous, more or less 

 infiltrated with rhizoidal filaments, the cortex narrow, of a few cell layers, 

 not in conspicuous anticlinal rows ; sporangia tetrapartite, formed in the 

 inner cortex; carpogenic branches formed on inner cortical cells, three 

 celled, one or more on a common supporting auxiliary cell which may also 

 bear lateral cells; sterile nutritive filaments intermixed with carpospore 

 masses in the mature cystocarp, which is completely immersed or some- 

 what projecting.
