EXPLANATIONS OF FIGURES IN PLATE XXIV. 
Illustrating Mr. Petcb’s Paper on the genus Endocalyx. 
Endocalyx melanoxanthus (B. & Br.) 
Fig. 1. An unopened pustule of yellow hyphae. x 20. 
Fig. 2. Open pustule, viewed from above, showing the yellow ring and black disk of spores, 
x 20. 
Fig. 3. A similar pustule viewed laterally, raised by the upturned cuticle of the substratum, 
x 20. 
Fig. 4. An old weathered pustule : the loose scales of the ring blown or washed away, x 20. 
Fig. 5. The same, viewed laterally, x 20. 
Fig. 6. A recently opened pustule, with a very irregular granular ring, x 40. 
Fig. 7. Vertical section through an open pustule: column of sporophores and spores in the 
centre, surrounded by a zone of agglutinated yellow hyphae, which appears as a ring at the surface : 
the outer layer of hyphae in contact with the substratum is blackened, x 40. 
Fig. 8. The perfect columnar form, surrounded at the base by the upturned cuticle and a ring 
of yellow fragments, x 20. 
Fig. 9. The columnar form without a basal ring : this shows a constriction which probably 
indicates a temporary cessation of growth : the lower part of the cylinder is split longitudinally. X 20. 
Fig. 10. Vertical section through a fructification of the type of Fig. 8, showing the basal 
yellow zone, only the inner layers of which are produced to form the wall of the column, x 40. 
Fig. 1 1 . Part of a sporophore, with immature spores, x 300. 
Fig. 12. Spores, x 300. 
Fig. 13. A fragment of the yellow wall, x 300. 
Endocalyx cinctus , Petch. 
Fig. 14. Fructification with abruptly expanding funnel, x 20. 
Fig. 15. Fructification with gradually expanding funnel. X 20. 
Fig. 16. Longitudinal section of fructification ; the conidiophores and external hyphae of the 
funnel are continued through the black cylinder into the substratum, x 40. 
Fig. 17. Spores, x 300. The single hyaline immature spore is x 600. 
Endocalyx Thwaitesii, B. & Br. 
Fig. 18. Copy of Berkeley and Broome’s figure. The substratum is Oncosperma , and should be 
fluted and tomentose. The cup at the base ought to be an annulus, through which the stalk passes 
loosely. The whole fungus should be minutely roughened (? normal), not floccose as in the figure, 
x about 50. 
Fig. 19. Spores, x 300. 
N.B. — In Figs. 7, 10, 16, the spores are represented diagrammatically as far as their size is 
concerned.
