Book Description
Athanasiadis, Athanasios, and David L. Ballantine. Anatomy and Classification of the Mesophyllaceae (Corallinales, Rhodophyta), based on Phylogenetic Principles. Smithsonian Contributions to Botany, number 118, xx + XXX pages, 83 figures, 2024. - A phylogenetic analysis shows the Mesophyllaceae to comprise the subfamilies Clathromorphoideae Athanas. et D. L. Ballant., subfam. nov., Protomesophylloideae Athanas. et D. L. Ballant., subfam. nov., and Mesophylloideae Athanas. et D. L. Ballant., subfam. nov., the last one including the main core of species previously assigned to Mesophyllum and Leptophytum. The Clathromorphoideae comprise the genera Clathromorphum, Neopolyporolithon, Callilithophytum, and the monotypic Clathmoroa Athanas. et D. L. Ballant., gen. nov. based on C. tubiformis (Y. M. Chamb., R. E. Norris et G. W. Maneveldt) Athanas. et D. L. Ballant., comb. nov. from South Africa. Protomesophylloideae is monotypic, based on Protomesophyllum ameleteton Athanas. et D. L. Ballant., sp. nov. from southern Australia-New Zealand-Chatham. The Mesophylloideae comprise the tribes Amphithallieae Athanas. et D. L. Ballant., trib. nov., Melyvonneeae Athanas. et D. L. Ballant., trib. nov., and the Magnephyceae Athanas. et D. L. Ballant., trib. nov. Amphithallieae include the genera Amphithallia, Synarthrophyton, Carlskottsbergia, Capensia, and the monotypic Kerguelena Athanas. et D.L. Ballant., gen. nov. (type: K. dickiei Athanas. et D.L. Ballant., comb. et nom. nov.) and Masoniana Athanas. et D.L. Ballant., gen. nov. (type: M. kraftii Athanas. et D.L. Ballant., comb. et nom. nov. from southern Australia). Melyvonneeae include the genera Phragmope, Mesophyllum, Melyvonnea, Perithallis, Thallis, Sunesonia, Printziana (comprising the type and P. insignis (Foslie) Athanas. et D.L. Ballant., comb. nov. from New Zealand), and the new monotypic Macroblastum Athanas. et D.L. Ballant., gen. nov. based on the Mediterranean M. dendrospermum Athanas. et D.L. Ballant., comb. et nom. nov. Magnephyceae include the genera Kvaleya, Leptophytum, Leptothallia Athanas. et D.L. Ballant., gen. nov. (based on L. acervata (Foslie) Athanas. et D.L. Ballant., comb. nov. from South Africa), Macedonis Athanas. et D.L. Ballant., gen. nov. (including the Aegean generitype M. tethygenis Athanas. et D.L. Ballant., comb. et nom. nov., and the NW Pacific M. julieae (Athanas. et W.H. Adey) Athanas. et D.L. Ballant., comb. nov., M. lamellicola (Athanas. et W.H. Adey) Athanas. et D.L. Ballant., comb. nov., and M. kymatodis (Athanas.) Athanas. et D.L. Ballant., comb. nov.), Hyperandri Athanas. et D.L. Ballant., gen. nov. (including the generitype from Pacific Mexico H. dawsonii Athanas. et D.L. Ballant., comb. et nom. nov., the Canarian-Caribbean H. bisporum (Foslie) Athanas. et D.L. Ballant., comb. nov., and the Thai H. siamense (Foslie) Athanas. et D.L. Ballant., comb. nov.), the monotypic Ectocarpa Athanas. et D.L. Ballant., gen. nov. (based on E. capverdensis Athanas. et D.L. Ballant., comb. et nom. nov.), Magnephycus Athanas. et D.L. Ballant., gen. nov. (including the Caribbean generitype M. ornatus (Foslie et M. Howe) Athanas. et D.L. Ballant., comb. nov., the southern Australian M. engelhartii (Foslie) Athanas. et D.L. Ballant., comb. nov., and the Indo-Pacific M. simulans (Foslie) Athanas. et D.L. Ballant., comb. nov.), Mastophoropsis, and Phymatolithopsis (the last genus as incertae sedis). As outgroups are selected two genera of Melobesiaceae: Melobesia (Melobesioideae) and Orthocarpa Athanas. et D.L. Ballant., gen. nov. (type: O. epicklonia Athanas. et D.L. Ballant., sp. nov. from southern Australia, placed in the Orthocarpoideae Athanas. et D.L. Ballant., subfam. nov.). These share production of a fusion cell/gonimoblast just below the carpogonia and development of both lateral and orthostichous carposporangia, whereas the Mesophyllaceae develop carposporangia mainly laterally and produce a fusion cell/gonimoblast at the level of supporting cells. A further character distinguishing the Mesophyllaceae is the development of a cell tube - a prerequisite to transfer the zygote beyond the hypogynous cell to the subtending supporting (auxiliary) cell
