Corynophoron (NYL.) DUVIGN. Lejeunia, Mem. no. 14: 44 (1956) (see Note 21). Spores fusiform-cylindric, 3-7-septate (rarely up to 16-septate). Apothecia not hypophysate. Cephalodia sacculate or protosacculate, smoothly globose to commonly indentedscrobiculate or rarely cristate, with uniform or dimorphous cortex. Type species, St. ramulosum (Sw.) RAUSCH. Other species: St. argus HOOK. F. et TAYL. em. TH. FR., St. atlanticum (LAMB) LAMB, St. colensoi BAB., St. corticatulum NYL., St. crambidiocephalum LAMB, St. delisei BORY, St. didymicum LAMB, St. dusenii LAMB, St. fronduliferum LAMB, St. halei LAMB, St. implexum TH. FR., St. melanopotamicum LAMB, St. meyeri B. STEIN, St. microcarpurn M~~LL. ARG., St. novogranatense LAMB, St. pachycephalum VAIN., St. philippinense RAS., St. pseudomassartianum LAMB, St. rubiginosum PERS., St. rugulosum LAMB, St. salazinum (BORY) F ~E, St. staufferi LAMB, St. stenospermum (LAMB) LAMB, St. trachyphloeum LAMB, St. wadei LAMB. Subsect. C. Dactyloideum (LAMB) LAMB (n. stat.) Syn. Stereocaulon subgen. Holostelidium sect. Dactyloideum LAMB, Canad. J. Bot. 29: 565 (1951). Spores vermiform, (7-) 8-13-septate. Apothecia not hypophysate. Cephalodia protosacculate, finally digitately divided (dactylae form), with uniform cortex. Hypothecium pigmented (dark brown). Type and only known species, St. strictum TH. FR. (see Note 22). Sect. 2. Redingeria LAMB Canad. J. Bot. 29: 565 (1951). - Gymnocaulon DUVIGN. Lejeunia, Mem. no. 14: 14, 41, 46, 50 (1956) (see Note 23). Pseudopodetia simple or sparingly branched; no phyllocladioid branchlets developed; cephalodia sacculate (sometimes indistinctly so). Type species, St. caespitosum RED. Other species: St. gregarium RED., St. loricatum LAMB. Supplementary Notes 1. Stereocaulon subgen. Platycladium DUVIGN. Nom. inval., no Latin diagnosis given. No type species designated by DUVIGNEAUD. 2. Stereocaulon subgen. Pilophoropsis DUVIGN. (non Stereocaulon subgen. Pilophoropsis (LAMB) LAMB). Nom. inval., no Latin diagnosis given. St. sphaerophoroides TUCK. (in the sense of St. azoreum (SCHAER.) NYL.) designated by DUVIGNEAUD as type species of his subgen. Pilophoropsis. 3. Stereocaulon subgen. Eustereocaulon sect. Paschalia JATTA. Sectional name spelt with small initial letter by JATTA. NO type species designated, but St. paschaale (L.) H<strong>OF</strong>FM. listed among other species. 4. Stereocaulon subgen. Enteropodium sect. Eustereocaulon ser. Granulata DUVIGN. St. paschale (L.) H<strong>OF</strong>FM. designated by DUVIGNEAUD as type species of ser. Granulata. 5. St. dactylophyllum FLORKE. Position in this section somewhat doubtful; it may possibly belong to sect. Denudata subsect. Botryoideum, although this would seem unlikely for phytogeographical reasons. 6. St. esterhuysenae LAMB. Position in this section somewhat doubtful. 7. St. supervestiens MAGN. Position in this section doubtful.
I. MACKENZIE LAMB: A Conspectus of Stereocaulon 199 Stereocaulon subgen. Eustereocaulon sect. Denudata JATTA. Sectional name spelt with small initial letter by JATTA. NO type species designated by JATTA, but St. vesuvianum PERS. listed among other species. We here lectotypify it on St. vesuvianum (lectotypif. nov.). Stereocaulon subgen. Enteropodium sect. Eustereocaulon ser. Umbilicata DUVIGN. St. denudatum FLORKE (syn. St. vesuvianum var. nodulosum (WALLR.) LAMB) designated by DUVIGNEAUD as type species. Lecanocaulon NYL. Now lectotypified by us on St. scutelligerum TH. FR. ("Stereocaulon salazinum" sensu NYL.), lectotypif. nov. NYLANDER, loc. cit., cited the following 3 species under Lecanocaulon, without designating a type: St. Iecanoreum NYL. (=St. strictum TH. FR.), St. salazinum (BORY) (in the sense of St. scutelligerum TH. FR., as plainly shown by NYLANDER'S figure), and St. pityrizans NYL. VAINIO, in making the combination Stereocaulon subgen. Lecanocaulon (NYL.), did not mention any species. Stereocaulon subgen. Cylindrocladium sect. Lecanocaulon (NYL.) DUVIGN. Comb. inval., no basionym indicated. Wrongly typified by DUVIGNEAUD on St. ramulosum (SW.) RAUSCH., a species not included in the protologue of Lecanocaulon. Stereocaulon subgen. Holostelidium sect. Ecephalodiata LAMB. St. virgatum ACH. designated by LAMB as type species of sect. Ecephalodiata. St. lavicola MAGN. Position in this section doubtful. St. verruciferum NYL. Syn. St. speciosum LAMB. Stereocaulon subgen. Lecidocaulon sect. Verruculata SAT6 St. exutum NYL. designated by SAT^ as type species of sect. Verruculata. Published 3 months later than sect. Botryoideum G. T. JOHNS. St. exile ASAH. Position in this subsection doubtful. Subgen. Pilophoropsis (LAMB) LAMB. None of the material of the only species, St. curtum (Rxs.) LAMB, seen to date shows the earliest stages of development necessary to determine conclusively whether the origin of the pseudopodetia is holostelideous or enteropodious, but the former seems more probable. Stereocaulon subgen. Cylindrocladium DUVIGN. Nom. inval., no Latin diagnosis given. No type species designated by DUVIGNEAUD. Stereocaulon subgen. Rhopalophoron DUVIGN. St. sorediiferum HUE designated by DUVIGNEAUD as type species of subgen. Rhopalophoron. St. nesaeum NYL. (in the sense of St. massartianum HUE) designated as type species of ser. Protoclavulifera, and St. piluliferum TH. FR. as type species of ser. Euclavulifera. There is an error here, because one of the two series would have to be based on St. sorediiferum HUE and called ser. Rhopalophoron. St. paradoxum LAMB is doubtfully placed in subsect. Holostelidium pending discovery of fertile specimens. Stereocaulon subgen. Cylindrocladium sect. Corynophoron (NYL.) DUVIGN. Comb. inval., no basionym indicated. St. strictum TH. FR. Syn. St. explanaturn LAMB, St. lecanoreum NYL., St. peladense VAIN., St. substrictum HUE. Gymnocaulon DUVIGN. Nom. inval., no Latin diagnosis supplied. Chlorocaulum CLEMENTS. Based on Lichen salazinus BORY (in the sense of St. scutelligerum TH. FR.).
