Acarospora chlorophana [image of equals Pleopsidium chlorophanum (Wahlenb.) Zopf] - local reports of this taxon are referable to A. schleicheri. See discussion in Hafellner (1993b).

Acarospora glaucocarpa - cited from St. Louis Co. by Berry (1937) [as A. glaucocarpa var. verrucosa]; this report is the basis for the literature report in Gier & Kendrick (1972) [as var. verrucosa]. The specimen on which these reports are based, Berry 605, supposedly at US, could not be located. Three Missouri collections determined by Berry as A. glaucocarpa var. verrucosa, Berry 247 (F), Boone Co., and Hubricht B103 and B104 (both US), both from Franklin Co., are A. schleicheri. Gier & Kendrick (1972) also erroneously attribute a literature report of the typical variety to Berry (1937), and cite a specimen [as var. verrucosa] from Vernon Co. The specimen on which the Vernon Co. report is based, Kendrick s.n. 20 March 1971 (MCJ 11043), is Aspicilia contorta.

Anaptychia galactophylla [¸ Heterodermia galactophylla (Tuck.) W. L. Culb.] -local reports of this species are referable to Heterodermia echinata, although some early collections from elsewhere in the Midwest that were originally labelled A. galactophylla are Heterodermia speciosa.

Arthonia complanata -cited from Lincoln Co. by Berry (1937); this is the basis for the literature report in Gier & Kendrick (1972). The specimen upon which Berry's report is apparently based, Hubricht 780 (F), consists only of Hysterium pulicare Pers., a nonlichenized fungus.

Arthopyrenia sp. - cited from the Salt River basin by MBG (1974a, 1974b) and Seaward (1978). Taxonomic revisions within this group render the disposition of this report even to genus impossible without seeing the specimen.

Arthopyrenia lapponina - reported from Emma by Fink (1900) [as Pyrenula punctiformis var. fallax], and from Missouri by Fink (1935) [as Polyblastiopsis fallax]. These reports presumably form the basis for the literature reports by Gier & Jones (1954) and Gier & Kendrick (1972) [both, inexplicably, as Pannaria fallax], although the latter paper mistakenly attributes the report to Nelson (1911). These reports are presumably based on 2 specimens at MICH, both originally determined as Pyrenula punctiformis var. fallax: Demetrio 40 (1898) is referable to Mycoglaena meridionalis and Demetrio 62 (1900) is referable to Mycoglaena quercicola.

Arthopyrenia punctiformis - reported from Missouri by Fink (1910, 1935); these reports presumably are the basis for the literature reports by Gier & Jones (1954) and Gier & Kendrick (1972), although the latter reference mistakenly attributes the citation to Fink (1900). This taxon was also cited from Pike Co. by Pech (1866) [as Verrucaria punctiformis]. No confirming specimens have been located, and local reports are almost certainly based on misidentifications.

ARTHOTHELIUM A. Massal.

Arthothelium sp. image of caratWetmore (1992a): Taney Co.

Arthothelium hallii - cited by Berry (1937) from St. Louis Co.; this forms the basis for the literature report in Gier & Kendrick (1972). The specimen on which these reports are apparently based, Hubricht 815 (F)- originally determined by Berry - is a nonlichenized fungus. The only other Berry determination of this taxon located, Hubricht B121 (US), Franklin Co., is also nonlichenized.

Arthothelium ruanum - cited from Taney Co. by Wetmore (1992a), but a specimen originally determined as this species from the study area, Wetmore 69119 (NY), is Mycoporum pycnocarpoides.

Arthothelium spectabile A. Massal. image of caratLadd et al. (1994): cited from 7 cos. S1/2 Mo. See Pertusaria pustulata.

ASPICILIA A. Massal.

Aspicilia calcarea (L.) Mudd image of caratLadd (1996): Phelps Co. Note: this species is also cited Boone Co. by Berry (1936), but the specimen on which this report is based, Berry 330B (UMO), is L. valesiaca.

See Acarospora glaucocarpa.

Aspicilia laevata reported from Missouri by Fink (1935) [as Lecanora laevata] and a literature report by Gier & Jones (1954) [as Lecanora "laevigata"]. Gier & Kendrick (1972) exclude what they cite as the Engelmann Botanical Club (1911) [= Nelson (1911)] report of Lecanora "laevigata", rejecting it as a typographical error or unconfirmed synonym, but Nelson (1911) does not mention of any Lecanora. Gier & Kendrick (1972) do not mention the undocumented report in Gier & Jones (1954). If reference to a Missouri specimen of L. "laevigata" exists in the literature, it is likely to be a misspelled reference to L. laevata, and perhaps best referred to the related Aspicilia verrucigera.
