Holotype of Asaphomyces cholevae

UNITED STATES • “ Asaphomyces cholevae , slide from FH, #3980, barcode 00313725, holotype, on elytra of Choleva terminalis Lec. [as Clove terminalis , typing error?], from Kittery Point , Maine, York County ( USA), 07-1906, leg. R. Thaxter ”; FH [ 00313725 ]. [consists of four mature thalli in fair condition ( Fig. 19E )]

Remarks

First record from Denmark. Separation of A. cholevae and A. tubanticus has been widely discussed ( Majewski 1994b; Santamaria 2003). Tavares (1985) questioned the presence of A. cholevae in Europe, and separated it from A. tubanticus because of the broad perithecium with tapering neck and slender apex of the latter species, whereas a broad apex and a ± cylindrical perithecium were reported for A. cholevae . Synonymy has been suggested by Rossi & Máca (2006) after examining abundant material occurring on the same host of the type series, i.e., Sciodrepoides fumatus subsp. terminans (LeConte) from the USA. We agree with this opinion because we had the opportunity to study a large series of thalli in which the morphological variation cannot be explained in terms of separate species supported by habitus, nor by habitat or distribution. At first, A. tubanticus was restricted to larger thalli, bearing more perithecia and appendages, but between the two extremes there is a large number of intermediate forms, without discontinuities. Also, to support this idea, we have studied the type from FH (see above under other material examined) which include small thalli ( Fig. 19E ).
