The Lichens and Allied Fungi of Mercer County,
New Jersey
Dennis P. waters* and James c. Lendemer2
ABSTRACT. - A checklist of the lichens and allied fungi from Mercer County, New Jersey, is
presented. It was derived from inventories of 14 tracts of preserved and undeveloped land, which yielded 905
collections and 174 taxa. These include 37 new records for New Jersey, two of which, Catinaria neuschildii
and Strangospora pinicola, have been rarely reported from North America. It also includes Agonimia
flabeltiformis, which is newly reported for North America from localities throughout the Appalachian and
Ozark Mountains. Catillaria patteeana is described as new to science as well These inventories demonstrate
that substantial lichen diversity remains undiscovered even in densely populated regions of the Mid-Atlantic
characterized by highly fragmented and disturbed natural landscapes with relatively small areas of unaltered,
contiguous core-natural habitat
KEYWORDS. - Biogeography, Coastal Plain, diabase, floristics, Piedmont, rare species, species-
richness, symbiosis.
Usnea cavernosa Tuck. - C.C. Frost made a collection in 1849 at Five Mile Woods, Lawrence Township,
that he assigned to this species (Frost s.n., MIN[n.v.]). The range of the species is not known to
include New Jersey (Brodo et al. 2001, Waters & Lendemer in press) and the record likely
corresponds to U. trichodea.
Appendix n - description of a new Catillaria Species
Catillaria patteeana D.P. Waters & Lendemer, sp. nov.
Mycobank #829587.
DIAGNOSIS. - Similar to Catillaria lenticularis but differing in the presence of soredia.
TYPE: U.S.A. NEW JERSEY. MERCER CO.: Hopewell Township, Hillman Tract (D&R
Greenway), adjacent Hopewell-Princeton Rd., mixed hardwood forest (Acer, Carya, Fagus) with diabase
boulders, 1 Aug. 2017, on siliceous rock, D.P. Waters 2966 (NY!, holotype).
DESCRIPTION. - Thallus crustose, thin, continuous but frequently cracked, minutely rimose-
areolate, dull, green to green-brown; soralia small, 0,5-0.2 mm in diameter, ellipsoid to elongate and
irregular in outline, forming along the cracks in the thallus and margins of the apothecia; soredia Fine, light
gray-green to green-gray, lighter in color than thallus, 15-30(-50) pm in diameter; apothecia biatorine,
immersed to sessile, plane to slightly convex, 0.2-0.4 mm in diameter; discs brown, epruinose; margins
opaque white to light brown, smooth, epruinose; epihymenium brown, not inspersed with granules; hymenium
hyaline, hypothecium hyaline, exciple hyaline, outer portions paraplectenchymatous; paraphyses simple,
apices abruptly swollen with brown caps; asci Cati1laria-type\ ascospores: 8 per ascus, ellipsoid, hyaline, 1 -
septate, (6ù)8ù9(ù15) x 2-3(-5) pm (Fig. 5). Photobiont coccoid green alga, Trebouxioid, cells globose, 6-
10 pm in diameter.
ETYMOLOGY. - The species is named in honor of Dr. Howard H. Pattee, emeritus professor at the
Thomas J. Watson School of Engineering and Applied Science at Binghamton University, who was DPWÆs
Ph.D. adviser and remains his mentor and friend. Howard is a biophysicist and theoretical biologist who
studies the origin of life and symbolic control of physical systems. A collection of his papers 1967-2007 was
recently published (Pattee & Rqczaszek-Leonardi 2012).
ECOLOGY and DISTRIBUTION. - This species is so far known from a single location in central New
Jersey, in eastern North America. It was found growing on a siliceous outcrop in a mixed hardwood forest
near the top of a south-facing ridge at an elevation of 100 meters (328 ft.). Other taxa collected on the same
outcrop were Caloplaca sideritis and Leprocaidon adhaerens. It is noteworthy that despite the extensive
studies of sorediate crustose lichens in New Jersey and the surrounding region by the second author, this
species was not encountered previously.
DISCUSSION. - Catillaria patteeana is most notably distinguished from other members of the genus
by the combination of its saxicolous habit and the production of soredia (Hertel et al. 2007, Kilias 1981,
McCune 2017). Although the rimose-areolate thallus and apothecia with well-developed pale margins are
somewhat unusual when compared to common taxa such as C. lenticularis (Ach.) Th. Fr. and C. nigroclavata,
the placement of the taxon in Catillaria is logical when considering the Catillaiia-type asci, capitate
paraphyses with brown pigmentation, and small, 2-celled ascospores that lack a gelatinous halo. In eastern
North America, the principal saxicolous species of Catillaria are C. lenticularis on calcareous substrates and
G chalybeia (Borrer) A. Massal. on siliceous substrates (Brodo 2016). Catillaria patteeana more closely
resembles C. lenticularis in thallus and apothecial morphology but differs from both species in the presence
of soredia.
Based on the overall appearance and coloration of the thallus and apothecia, in the field the new
species would be mostly likely to be confused with Halecania or Lecania. Nonetheless, it differs from both
genera in having biatorine apothecia (vs. lecanorine in both Halecania and Lecania). Halecania does share
the Catillaria-uscm type and small, two-celled, hyaline ascospores with the new species. However, in
addition to its different apothecial type, Halecania species differ from G patteeana in typically lacking
demonstrated here, the lichens of central New Jersey have previously been little studied. Furthermore, while
the occurrence of rare or narrowly endemic taxon may seem somewhat improbable given the overall
fragmented natural landscape of the study area, it should be noted that similar taxa have been found on rock
outcrops in northern New Jersey and adjacent Pennsylvania (e.g., Bacidia phyllopsoropsis R.C. Harris &
Lendemer; see Harris & Lendemer 2006).

capitate paraphyses with brown pigmentation and in often producing substances such as argopsin (Coppins
1989, Fryday & Coppins 1996, Mayrhofer 1987). Likewise, Lecania species differ from G patteeana in
having Bacidia-type asci (Ekman 1996; Mayrhofer 1987,1988).
The discovery of the present species in central New Jersey is somewhat surprising given the
attention that has been given to typically sterile, asexually reproducing crustose lichens in fee region by the
second author (e.g., Hodkinson & Lendemer 2012; Lendemer 2013, 2016). Nonetheless, as we have
