Scopinella from Argentina
Romina Sánchez, 23-09-2011 19:16

Dear Dr. Malloch,
we saw in the forum your chat with Pimpek and we're interested in Scopinella's papers, too.

We have found a specimen of Scopinella on leaves of Cortaderia selloana (Poaceae) and we think it could be a new species. However we haven't got bibliographic material about S. gallicola and S. pleiospora.

We attached a plate. The ascospores are 7.5-9.5 x 5.5-8.5 µm.

Best wishes,
Lucrecia, Virginia and Romina

Re : Scopinella from Argentina
hello

(if I may "chip in") nothing on S. pleiospora, but this the description of S. gallicola (from "Scopinella gallicola, a new species from rust galls of Endocronartium harknessii on Pinus contorta" A . TSUNEDA AND Y . HIRATSUKA (CJB vol. 59)


TYPUS: In gallis Endocronartii harknessii (J. P. Moore) Y . Hiratsuka in Pinus contorta Dougl . var. latifolia Engelm. , CF B 20831.


Ascocarps nonstromatic, superficial; bases globose, at first hyaline and semitransparent, then becoming dark brown to black, 80-230 p.m diameter, with thick-walled peridial hyphae, hyaline, brown at the base, up to 150 x 5 p.m; necks straight or slightly bent, dark brown to black, pale or hyaline at the apices, slightly tapering toward the apices, mostly 230-370 u.m long, (18—)30— 45(-55) p,m wide; ostiolar hyphae rarely present.


Ascocarp peridium, dark brown to black, two- to five-layered, 9-25 p-m thick. Peridial cells isodiametric in surface view, 3-17 p.m diameter, 2- 7 p.m thick, with moderately thick walls 1-2 p.m thick. Paraphyses moniliform, 2.5-8.0 p,m diameter. Asci lining sides of the centrum wall , hyaline, 2- to 4-spored, clavate, usually short-stipitate, soon becoming evanescent, 12 - 26 x 5.0-7.5 p.m. Ascospores unicellular, barrel-
shaped, pale brown, brown to black in mass, hyaline at the ends, smooth, 3.5-8.0 x 2.9-6.5 p.m. ?


clearly a different taxon to what you have found


un cordial saludo! / best wishes

Re : Scopinella from Argentina

Hello Chris,


you're right, S. gallicola has nothing to do with our species. Thank you very much for the information!!!

Regard to S. pleiospora, we found it in the Index Fungorum (www.indexfungorum.org) list of Scopinella's species and we don't know when it was rejected as a member of the genus.

Cordialement,
